1. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

Business—Fortinet, Inc. (“Fortinet”) was incorporated in Delaware in October 2000 and is a leading provider of network security appliances and Unified Threat Management (UTM) network security solutions to enterprises, service providers and government entities worldwide. Fortinet’s solutions are designed to integrate multiple levels of security protection, including firewall, virtual private networking, antivirus, intrusion prevention, web filtering, antispam and WAN acceleration.

Basis of Presentation and Preparation—The condensed consolidated financial statements include the accounts of Fortinet and its wholly owned subsidiaries (collectively, the “Company,” “we,” “us” or “our”). All intercompany transactions and balances have been eliminated in consolidation. The accompanying condensed consolidated balance sheet as of March 31, 2010, the condensed consolidated statements of operations for the three months ended March 31, 2010 and March 29, 2009, and the condensed consolidated statements of cash flows for the three months ended March 31, 2010 and March 29, 2009 are unaudited. The condensed consolidated balance sheet data as of December 31, 2009 was derived from the audited condensed consolidated financial statements which are included in our Annual Report on Form 10-K (“Form 10-K”). The accompanying statements should be read in conjunction with the audited condensed consolidated financial statements and related notes contained in our Form 10-K.

The accompanying unaudited interim condensed consolidated financial statements for the three months ended and as of March 31, 2010 and March 29, 2009 have been prepared on the same basis as the audited condensed consolidated statements and reflect all adjustments, consisting of normal recurring adjustments which are, in the opinion of management, necessary for a fair presentation of our financial position, results of operations, and cash flows for the interim period presented. The statements have been prepared in accordance with accounting principles generally accepted in the United States of America (“U.S. GAAP” or “GAAP”) pursuant to the rules and regulations of the Securities and Exchange Commission (“SEC”). Accordingly, certain information and footnote disclosures normally included in financial statements prepared in accordance with U.S. GAAP have been condensed or omitted pursuant to such rules and regulations. The results of operations for the three months ended March 31, 2010 are not necessarily indicative of the operating results for any subsequent quarter, for the full fiscal year or any future periods.

Until the second quarter of fiscal 2009, we had a 52- to 53-week year ending on the Sunday closest to December 31 of each year. Commencing in the third quarter of fiscal 2009, we began operating and reporting financial results on a calendar quarter and year basis. Our first quarter of fiscal 2009 ended on March 29, 2009. The first quarters of 2010 and 2009 comprised of 90 days and 91 days, respectively.

Use of Estimates—The preparation of condensed consolidated financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities at the date of the condensed consolidated financial statements and the reported amounts of revenues and expenses during the reporting period. Such management estimates include implicit service periods for revenue recognition, litigation and settlement costs and other loss contingencies, sales returns and allowances, reserve for bad debt, inventory write-offs, reserve for warranty costs, valuation of deferred tax assets, and tangible and intangible assets. We base our estimates on historical experience and also on assumptions that we believe are reasonable. Actual results could differ from those estimates.

Certain Significant Risks and Uncertainties—We are subject to certain risks and uncertainties that could have a material adverse effect on our future financial position or results of operations, such as the following: changes in level of demand for our products and services, seasonality, the timing of new product introductions, price and sales competition and our ability to adapt to changing market conditions and dynamics, changes in the expenses caused, for example, by fluctuations in foreign currency exchange rates, management of inventory, internal control over financial reporting, market acceptance of our new products and services, demand for UTM products and services in general, failure of our channel partners to perform, the quality of our products and services, general economic conditions, challenges in doing business outside of the United States of America, changes in customer relationships, litigation, or claims against us based on intellectual property, patent, product regulatory or other factors (Note 7), product obsolescence, and our ability to attract and retain qualified employees.

FORTINET, INC. AND SUBSIDIARIES

NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS—(Continued)

(Unaudited)

We rely on sole suppliers and independent contract manufacturers for certain of our components and one third-party logistics company for distribution of some of our products. The inability of any of these parties to fulfill our supply and logistics requirements could negatively impact our future operating results.

Concentration of Credit Risk—Financial instruments that subject us to concentrations of credit risk consist primarily of cash, cash equivalents, investments, and accounts receivable. We maintain our cash and cash equivalents in fixed income securities with major financial institutions, which our management assesses to be of high credit quality, in order to limit the exposure of each investment. Deposits held with banks may exceed the amount of insurance provided on such deposits.

Credit risk with respect to accounts receivable in general is diversified due to the number of different entities comprising our customer base and their location throughout the world. We perform ongoing credit evaluations of our customers and generally do not require collateral on accounts receivable. We maintain reserves for estimated potential credit losses.

At March 31, 2010 and December 31, 2009, one distributor customer accounted for 11% and 15%, respectively, of net accounts receivable.

During the quarters ended March 31, 2010 and March 29, 2009, one distributor customer accounted for 11% and 12%, respectively, of total net revenues.

Fair Value of Financial Instruments—Accounting Standards Codification (ASC) 825 (formerly referred to as Financial Accounting Standards Board Statement No. 107, Disclosures about Fair Value of Financial Instruments) requires disclosure of fair value information about financial instruments, whether or not recognized in the balance sheet, for which it is practicable to estimate that value. Due to their short-term nature, the carrying amounts reported in the condensed consolidated financial statements approximate the fair value for cash and cash equivalents, accounts receivable, and accounts payable.

Comprehensive Income—ASC 220 (formerly referred to as FASB Statement No. 130, Reporting Comprehensive Income) establishes standards for the reporting and displaying of comprehensive income and its components. Comprehensive income includes certain changes in equity from non-owner sources that are excluded from net income. Specifically, cumulative foreign currency translation adjustments and unrealized gains and losses are included in comprehensive income. Comprehensive income has been reflected in the condensed consolidated statements of stockholders’ equity and comprehensive income.

Foreign Currency Translation—Assets and liabilities of foreign subsidiaries are translated into U.S. dollars using the exchange rates in effect at the balance sheet dates and revenue and expenses are translated using average exchange rates during the period. The resulting foreign translation adjustments are recorded in accumulated other comprehensive income (loss). Foreign currency transaction gains and (losses) of $(0.3) million and $0.5 million, are included in other income (expense), net for the quarter ended March 31, 2010 and March 29, 2009, respectively.

Cash, Cash Equivalents and Investments—We consider all highly liquid investments, purchased with original maturities of three months or less, to be cash equivalents. Cash and cash equivalents consist of cash on-hand, balances with banks, and highly liquid investments in money market funds, commercial paper, government securities, certificates of deposit, and corporate debt securities.

We classify our investments as available-for-sale at the time of purchase since it is our intent that these investments are available for current operations, and include these investments on our balance sheet as either short-term or long-term investments depending on their maturity at the time of purchase. Investments with original maturities greater than three months that mature less than one year from the condensed consolidated balance sheet date are classified as short-term investments. Investments with maturities greater than one year from the condensed consolidated balance sheet date are classified as long-term investments.

FORTINET, INC. AND SUBSIDIARIES

NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS—(Continued)

(Unaudited)

Investments are considered to be impaired when a decline in fair value is judged to be other-than-temporary. We consult with our investment managers and consider available quantitative and qualitative evidence in evaluating potential impairment of our investments on a quarterly basis. If the cost of an investment exceeds its fair value, we evaluate, among other factors, general market conditions, the duration and extent to which the fair value is less than cost, and our intent and ability to hold the investment. Once a decline in fair value is determined to be other-than-temporary, an impairment charge is recorded and a new cost basis in the investment is established.

Inventory—Inventory is recorded at the lower of cost (using the first-in, first-out method) or market, after we give appropriate consideration to obsolescence and inventory in excess of anticipated future demand. In assessing the ultimate recoverability of inventory, we are required to make estimates regarding future customer demand, the timing of new product introductions, economic trends and market conditions. If the actual product demand is significantly lower than forecasted, we could be required to record additional inventory write-downs, which could have an adverse impact on our gross margins and profitability.

Deferred Cost of Revenues—Deferred cost of revenues represent the unamortized cost of products associated with ratable products and services revenue, which is based upon the actual cost of the hardware sold and is recognized over the service periods of the arrangements. Deferred cost of revenue associated with short-term deferred revenue is classified as short-term and deferred cost of revenue associated with long-term deferred revenue is classified as long-term.

Property and Equipment—Property and equipment are stated at cost. Depreciation is computed using the straight-line method over the estimated useful lives of the assets, generally one to three years. Evaluation units are transferred from inventory at cost and are amortized over one year from the date of transfer. Leasehold improvements are amortized over the shorter of the estimated useful lives of the improvements or the lease term.

Impairment of Long-Lived Assets—We evaluate events and changes in circumstances that could indicate carrying amounts of long-lived assets, including intangible assets, may not be recoverable. When such events or changes in circumstances occur, we assess the recoverability of long-lived assets by determining whether the carrying value of such assets will be recovered through undiscounted expected future cash flows. If the total of the future undiscounted cash flows is less than the carrying amount of those assets, we record an impairment charge in the period in which we make the determination. If such assets are considered to be impaired, the impairment to be recognized is measured by the amount by which the carrying amount of the assets exceeds the fair value of the assets.

Deferred Revenue—Deferred revenue consists of amounts that have been invoiced but that have not yet been recognized as revenue.

Income Taxes—We record income taxes using the asset and liability method, which requires the recognition of deferred tax assets and liabilities for the expected future tax consequences of events that have been recognized in our financial statements or tax returns. In estimating future tax consequences, generally all expected future events other than enactments or changes in the tax law or rates are considered. We assess the likelihood that some portion or all of our deferred tax assets will be recovered from future taxable income within the respective jurisdictions, and to the extent we believe that recovery does not meet the “more-likely-than-not” standard, based solely on its technical merits as of the reporting date, we establish a valuation allowance. We consider many factors when evaluating and estimating our tax positions and tax benefits, which may require periodic adjustments and which may not accurately anticipate actual outcomes.

We operate in various tax jurisdictions and are subject to audit by various tax authorities. We provide for tax contingencies whenever it is deemed more likely than not that a tax asset has been impaired or a tax liability has been incurred for events such as tax claims or changes in tax laws. Tax contingencies are based upon their technical merits, relevant tax law and the specific facts and circumstances as of each reporting period. Changes in facts and circumstances could result in material changes to the amounts recorded for such tax contingencies.

Advertising Expense—Advertising costs are expensed when incurred and are included in operating expenses in the accompanying condensed consolidated statements of operations. Our advertising expenses were not significant for any periods presented.

Stock-Based Compensation—Effective January 2, 2006, we adopted ASC 718 (formerly referred to as SFAS 123R). For our stock option grants made subsequent to January 2, 2006, we have accounted for such stock-based awards to employees in accordance with ASC 718, which requires compensation expense related to share-based transactions, including employee stock options, to be measured and recognized in the financial statements based on fair value. Under ASC 718, the fair value of each option award is estimated on the grant date using the Black-Scholes option pricing model.

FORTINET, INC. AND SUBSIDIARIES

NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS—(Continued)

(Unaudited)

Research and Development Costs—Research and development costs are expensed as incurred.

Software Development Costs—The costs to develop software have not been capitalized as we believe our current software development process is essentially completed concurrent with the establishment of technological feasibility.

Revenue Recognition—We derive revenue from sales of products, including appliances and software, and services, including subscription, support and other services. Our appliances include operating system software that is integrated into the appliance hardware and is deemed essential to its functionality. As a result, we account for revenue in accordance with ASC 985-605 (formerly referred to as Statement of Position 97-2 (SOP 97-2) Software Revenue Recognition), and all related interpretations.

No revenue can be recognized until all of the following criteria have been met:

•

Persuasive evidence of an arrangement exists. Binding contracts or purchase orders are generally used to determine the existence of an arrangement.

•

Delivery has occurred. Delivery occurs when we fulfill an order and title and risk of loss has been transferred or upon delivery of the service contract registration code.

•

The fee is fixed or determinable. We assess whether the fee is fixed or determinable based on the payment terms associated with the transaction. In the event payment terms differ from our standard business practices, the fees are deemed to be not fixed or determinable and revenue is recognized when the payments become due, provided the remaining criteria for revenue recognition have been met.

•

Collectability is probable. We assess collectability based primarily on creditworthiness as determined by credit checks and analysis, as well as payment history. Payment terms generally range from 30 to 90 days from invoice date.

For arrangements which include customer acceptance criteria, no revenue is recognized prior to acceptance. We recognize product revenue on sales to distributors that have no right of return and end-customers upon shipment of the appliance, once all other revenue recognition criteria have been met. We also make sales through distributors under agreements that allow for rights of returns. We recognize product revenue on sales made through such distributors upon sale by the distributor to the end-customer, at which time the rights of return lapse. Substantially all of our products have been sold in combination with services which consist of subscriptions and/or support. Subscription services provide access to our antivirus, intrusion prevention, web filtering, and anti-spam functionality. Support services include rights to unspecified software upgrades, maintenance releases and patches, telephone and internet access to technical support personnel, and hardware support.

We commence our subscription and support services on the date the customer registers the appliance. The customer is then entitled to service for the stated contractual period beginning on the registration date.

We use the residual method to recognize revenue when an arrangement includes one or more elements to be delivered at a future date and vendor-specific objective evidence (“VSOE”) of the fair value of all undelivered elements exists. Under the residual method, the fair value of the undelivered elements is deferred and the remaining portion of the contract fee is recognized as product revenue. In cases where VSOE of fair value of the undelivered elements does not exist, it is typically due to a lack of VSOE on the subscription and support services for that specific arrangement; revenue for the entire arrangement is recognized ratably over the performance period of the undelivered elements. Revenue related to these arrangements is included in ratable product and services revenue in the accompanying condensed consolidated statements of operations. VSOE of fair value for elements of an arrangement is based upon the pricing for those services when sold separately. Revenue for professional services and training is recognized upon completion of the related services.

We offer certain sales incentives to channel partners. We reduce revenue for estimates of sales returns and allowances. Additionally, in limited circumstances we may permit end-customers, distributors and resellers to return our products, subject to varying limitations, for a refund within a reasonably short period from the date of purchase. We estimate and record reserves for sales incentives and sales returns based on historical experience.

Accounts Receivable—Trade accounts receivable are recorded at the invoiced amount, net of allowances for doubtful accounts and sales returns and allowances. The allowance for doubtful accounts is based on our assessment of the collectability of customer accounts. We regularly review the allowance by considering factors such as historical experience, credit quality, age of the accounts receivable balances and current economic conditions that may affect a customer’s ability to pay. The reserve for sales returns and allowances is based on specific criteria including agreements to provide rebates and other factors known at the time, as well as estimates of the amount of goods shipped that will be returned. To determine the adequacy of the sales returns and allowances, we analyze historical experience of actual rebates and returns as well as current product return information.

Warranties—We generally provide a one-year warranty on hardware products and a 90-day warranty on software. A provision for estimated future costs related to warranty activities is recorded as a component of cost of product revenues when the product revenues are recognized, based upon historical product failure rates and historical costs incurred in correcting product failures. In the event we change our warranty reserve estimates, the resulting charge against future cost of sales or reversal of previously recorded charges may materially affect our gross margins and operating results.

Accrued warranty activities are summarized as follows (in thousands):


	For The 3 Months Ended And As Of March 31, 2010			For The Year Ended And As Of December 31, 2009
Accrued warranty balance—beginning of the period	$	2,257		$	2,882

Recent Accounting Pronouncements

In January 2010, the FASB issued revised guidance on disclosures related to fair value measurements. This guidance requires new disclosures about significant transfers in and out of Level 1 and Level 2 and separate disclosures about purchases, sales, issuances, and settlements with respect to Level 3 measurements. The guidance also clarifies existing fair value disclosures about valuation techniques and inputs used to measure fair value. The new disclosures and clarifications of existing disclosures are effective for us beginning in the first quarter of 2010, except for the disclosures about purchases, sales, issuances, and settlements relating to Level 3 measurements, which will be effective for us in the first quarter of 2011. We do not expect the adoption to have a material impact on our financial statements.

In September 2009, the EITF reached a consensus on ASC 605-25 (formerly referred to as EITF 08-1, Revenue Arrangements with Multiple Deliverables). ASC 605-25 eliminates the criterion for objective and reliable evidence of fair value for the undelivered products or services. Instead, revenue arrangements with multiple deliverables should be divided into separate units of accounting if the deliverables meet both of the following criteria:

•

The delivered items have value to the customer on a stand-alone basis

•

If the arrangement includes a general right of return relative to the delivered items, delivery or performance of the undelivered items is considered probable and substantially in the control of the vendor.

FORTINET, INC. AND SUBSIDIARIES

NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS—(Continued)

(Unaudited)

ASC 605-25 eliminates the use of the residual method of allocation and requires, instead, that arrangement consideration be allocated, at the inception of the arrangement, to all deliverables based on their relative selling price (i.e., the relative selling price method). When applying the relative selling price method, a hierarchy is used for estimating the selling price for each of the deliverables. The hierarchy establishes that the method for determining estimated selling price should be chosen in the following order of priority:

•

VSOE of the selling price;

•

Third-party evidence (TPE) of the selling price – prices of the vendor’s or any competitor’s largely interchangeable products or services, in standalone sales to similarly situated customers; and

Best estimate of the selling price.

In September 2009, the FASB reached a consensus on ASC 985-605 (formerly referred to as EITF 09-3, Certain Revenue Arrangements That Include Software Elements). Arrangements to sell joint hardware and software products where the software and non-software components function together to deliver the product’s essential functionality will no longer be scoped into software accounting rules, but will be subject to non-software multiple element accounting guidance (ASC 605-25). ASC 985-605 and ASC 605-25 provide a list of items to consider when determining whether the software and non-software components function together to deliver a product’s essential functionality. ASC 985-605 must be adopted for arrangements entered into beginning January 1, 2011, and may be early-adopted. We plan to adopt ASC 985-605 and ASC 605-25 in the first quarter of 2011, and are currently evaluating the impact of adoption on our consolidated financial statements.

Fair Value Accounting—We adopted ASC 820 (formerly referred to as FASB Statement No. 157, Fair Value Measurement) effective January 1, 2008. ASC 820 establishes a valuation hierarchy for disclosure of the inputs to fair value measurement. This hierarchy prioritizes the inputs into three broad levels as follows:

Level 1—Inputs are unadjusted quoted prices in active markets for identical assets or liabilities.

Level 2—Inputs are quoted prices for similar assets and liabilities in active markets or inputs that are observable for the assets or liabilities, either directly or indirectly through market corroboration, for substantially the full term of the financial instruments.

Level 3—Inputs are unobservable inputs based on our own assumptions used to measure assets and liabilities at fair value. The inputs require significant management judgment or estimation.

The following table presents the fair value of our financial assets as of March 31, 2010 and December 31, 2009 using the ASC 820 input categories:


	March 31, 2010						December 31, 2009
	Aggregate Fair Value		Quoted Prices in Active Markets For Identical Assets		Significant Other Observable Remaining Inputs		Aggregate Fair Value		Quoted Prices in Active Markets For Identical Assets		Significant Other Observable Remaining Inputs

Total cash, cash equivalents and available-for-sale securities	$	280,937					$	260,314

We classify investments within Level 1 if quoted prices are available in active markets.

We classify items in Level 2 if the investments are valued using observable inputs to quoted market prices, benchmark yields, reported trades, broker/dealer quotes or alternative pricing sources with reasonable levels of price transparency.

We did not hold financial assets or liabilities which were recorded at fair value using inputs in the Level 3 category as of March 31, 2010 and December 31, 2009.

5. INCOME (LOSS) PER SHARE

Basic net income (loss) per share is computed by dividing net income attributable to common stockholders by the weighted-average number of common shares outstanding during the period. Diluted net income (loss) per share is computed by dividing net income attributable to common stockholders by the weighted-average number of common shares outstanding, plus the dilutive effects of stock options and warrants.

In November 2009, all of our outstanding convertible preferred stock converted into common stock in connection with our initial public offering. For periods that ended prior to such conversion, net income per share information is computed using the two-class method. The convertible preferred shares were entitled to receive annual non-cumulative dividends of $0.02, $0.05, $0.12, $0.12 and $0.30 per share for Series A, B, C, D, and E, respectively, payable prior and in preference to holders of common stock. After the payment of such dividends, convertible preferred shares were further entitled to receive a proportionate amount of any dividends paid on common stock on an if-converted basis. As a result of such dividend rights, the convertible preferred shares are considered to be participating securities. Under the two-class method of computing earnings per share, net income attributable to common stockholders is computed by an adjustment to subtract from net income the portion of current year earnings that the preferred shareholders would have been entitled to receive pursuant to their dividend rights had all of the year’s earnings been distributed. No such adjustment to earnings is made during periods with a net loss, as the holders of the convertible preferred shares had no obligation to fund losses. Accordingly, in the first quarter of 2009, we did not apply the two-class method. Basic net income (loss) per share is computed by dividing net income attributable to common stockholders by the weighted-average number of common shares outstanding during the period. Diluted net income (loss) per share is computed by using the weighted-average number of common shares outstanding, plus, for periods with net income attributable to common stock, the dilutive effects of stock options.

Net income per share information for the quarter ended March 29, 2009 gives effect to the repurchase of convertible preferred shares (Note 8). The excess of the fair value of the consideration paid for such preferred stock over the carrying value of the preferred stock represents a return to the preferred stockholders and is treated in a manner similar to the treatment of dividends paid to the holders of preferred stock in the computation of earnings per share. As a result, the premium paid is subtracted to derive net income attributable to common stockholders in determining earnings per share.

7. COMMITMENTS AND CONTINGENCIES

Leases and Minimum Royalties—We lease our facilities under various noncancelable operating leases, which expire through 2014. Rent expense was $1.7 million and $1.4 million for the three months ended March 31, 2010 and March 29, 2009, respectively. Rent expense is recognized using the straight-line method over the term of the lease.

We entered into a Settlement and Patent License Agreement with Trend Micro in January 2006 (see Litigation section below). The aggregate future noncancelable minimum rental payments on operating leases and minimum royalties payable if we continued paying under the Trend Micro Settlement and License Agreement as of March 31, 2010 are as follows (in thousands):

Total	$	19,351	$	7,000

Contract Manufacturer Commitments—Our independent contract manufacturers procure components and build our products based on our forecasts. These forecasts are based on estimates of future demand for our products, which are in turn based on historical trends and an analysis from our sales and marketing organizations, adjusted for overall market conditions. In order to reduce manufacturing lead times and plan for adequate component supply, we may issue purchase orders to some of our independent contract manufacturers which may not be cancelable. As of March 31, 2010, we had $19.1 million of open purchase orders with our independent contract manufacturers that may not be cancelable.

Litigation —In May 2004, Trend Micro Incorporated filed a complaint against us alleging that we infringed a Trend Micro patent related to antivirus software. In January 2006, we settled the lawsuit with Trend Micro. Pursuant to the settlement and license agreement, we initially paid Trend Micro $15.0 million. The settlement and license agreement provides for additional quarterly royalty payments, not expected to exceed 1% of our total revenue each quarter, through 2015. In November 2008, we filed a complaint against Trend Micro in the United States District Court for the Northern District of California alleging, among other claims, that the patents that are the basis for the ongoing royalty payments are invalid and consequently that we have no contractual obligation to pay the royalties.

(Unaudited)

Trend Micro moved to dismiss the case, and, in June 2009, the court dismissed the case without prejudice on procedural grounds, and we appealed the dismissal in July 2009. Based on the dispute, we have ceased paying royalties under the settlement and license agreement. In August 2009, Trend Micro filed a complaint against us in the Superior Court of the State of California for Santa Clara County alleging breach of contract and seeking a declaratory judgment that we are obligated to make certain royalty payments to Trend Micro. In December 2009, we withdrew our appeal of the June 2009 dismissal by the United States District Court for the Northern District of California and filed a new complaint against Trend Micro in the United States District Court for the Northern District of California alleging, among other claims, that the patents that are the basis for the ongoing royalty payments are invalid and consequently that we have no contractual obligation to pay royalties. We have continued to accrue expense based on the quarterly royalties provided for in the settlement and license agreement. In February 2010, Trend Micro filed demurrers in the state Superior Court action regarding Fortinet’s affirmative defenses that Fortinet has no obligation to pay royalties because the Trend Micro patents are invalid or unenforceable. In March 2010, Trend Micro filed a motion to dismiss our new complaint that we filed in the United States District Court for the Northern District of California. On May 3, 2010, the state court denied Trend Micro’s demurrer in its entirety. On May 12, 2010, the United States District Court for the Northern District of California denied Trend Micro’s motion to dismiss without prejudice and stayed the action before that court pending the conclusion of the state court action.

In January 2009, we filed a complaint against Palo Alto Networks, Inc., in the United States District Court for the Northern District of California alleging, among other claims, patent infringement. In September 2009, Palo Alto Networks filed a counterclaim against us alleging patent infringement. In May 2009, Enhanced Security Research, LLC (“ESR”) a non-practicing entity, filed a complaint in the United States District Court for the District of Delaware alleging patent infringement by us and other defendants. In August 2009, ESR filed a substantially similar complaint against us in the same court alleging infringement of the same patents. In September 2009, Deep Nines, Inc. filed, but did not serve us with, a complaint against us in the United States District Court for the Eastern District of Texas alleging that our products infringe certain of their patents. The Palo Alto Networks and ESR cases are currently at an early stage of the litigation process. The Deep Nines case has not yet been served.

In April 2010, an individual, a former stockholder of Fortinet, filed a class action lawsuit against us in the Superior Court of the State of California for the County of Los Angeles alleging violation of various California Corporate Code sections and related tort claims alleging misrepresentation and breach of fiduciary duty regarding the 2009 repurchase by Fortinet of shares of its stock while we were a privately-held company as discussed in Note 8 immediately below, “Stockholders’ Equity—Stock Repurchase”.

In addition to the above matters, we are subject to other litigation in the course of business. Although no assurance may be given, we believe that we are not presently a party to any litigation the outcome of which will individually or in the aggregate be reasonably expected to have a material adverse effect on our business, operating results, cash flows, or financial condition.

Indemnification—Under the indemnification provisions of our standard sales contracts, we agree to defend our customers against third-party claims asserting infringement of certain intellectual property rights, which may include patents, copyrights, trademarks, or trade secrets, and to pay judgments entered on such claims. Our exposure under these indemnification provisions is generally limited to the total amount paid by our customer under the agreement. However, certain agreements include indemnification provisions that could potentially expose us to losses in excess of the amount received under the agreement. To date, there have been no claims under such indemnification provisions.

8. STOCKHOLDERS’ EQUITY

Stock Repurchase—While we were a privately-held company, during the first six months of fiscal 2009, our board of directors approved a stock repurchase authorization. This repurchase authorization allowed us to repurchase up to $20.0 million of our convertible preferred and common stock at $4.25 per share through June 17, 2009. This repurchase authorization expressly excluded our board members and senior management. We repurchased 704,632 shares of common stock and 3,004,165 shares of convertible preferred stock for a total consideration of $15.7 million, out of which 416,177 shares of common stock and 1,476,000 shares of convertible preferred stock were repurchased in the first quarter of 2009 for total consideration of $8.0 million.

9. STOCK PLANS

2000 Stock Plan—During 2000, we adopted the 2000 Stock Option Plan, which was amended and restated in April 2006 and further amended in March 2008 (the “Amended and Restated 2000 Stock Plan”). The Amended and Restated 2000 Stock Plan includes both incentive and non-statutory stock options. Under the Amended and Restated 2000 Stock Plan, we may grant options to purchase up to 21,500,000 shares of common stock to employees, directors and other service providers at prices not less than the fair market value at date of grant for incentive stock options and not less than 85% of fair market value for non-statutory options. Options granted to a person who, at the time of the grant, owns more than 10% of the voting power of all classes of stock shall be at no less than 110% of the fair market value and expire five years from the date of grant. All other options generally have a contractual term of 10 years. Options generally vest over four years.

2008 Stock Plan—On January 28, 2008, our board of directors approved the 2008 Stock Plan (the 2008 Plan) and French Sub-Plan, which includes both incentive and non-statutory stock options. The maximum aggregate number of shares which may be subject to options and sold under the 2008 Plan and the French Sub-Plan is 5,000,000 shares, plus any shares that, as of the date of stockholder approval of the 2008 Plan, have been reserved but not issued under the 2000 Plan or shares subject to stock options or similar awards granted under the 2000 Plan that expire or otherwise terminate without having been exercised in full or that are forfeited to or repurchased by us.

Under the 2008 Plan and the French Sub-Plan, we may grant options to employees, directors and other service providers. In the case of an incentive stock option granted to an employee, who at the time of grant, owns stock representing more than 10% of the total combined voting power of all classes of stock, the exercise price shall be no less than 110% of the fair market value per share on the date of grant and expire five years from the date of grant, and options granted to any other employee, the per share exercise price shall be no less than 100% of the fair market value per share on the date of grant. In the case of a nonstatutory stock option and options granted to other service providers, the per share exercise price shall be no less than 100% of the fair market value per share on the date of grant.

2009 Equity Incentive Plan—On November 17, 2009, our board of directors approved the 2009 Equity Incentive Plan (the 2009 Plan) and French Sub-Plan, which includes awards of stock options, stock appreciation rights, restricted stock, restricted stock units, and performance units or performance shares. The maximum aggregate number of shares that may be issued under the 2009 Plan is 9,000,000 shares, plus any shares subject to stock options or similar awards granted under the 2008 Stock Plan and the Amended and Restated 2000 Stock Plan that expire or otherwise terminate without having been exercised in full and shares issued pursuant to awards granted under the 2008 Stock Plan and the Amended and Restated 2000 Stock Plan that are forfeited to or repurchased by the Company, with the maximum number of shares to be added to the 2009 Plan pursuant to such terminations, forfeitures and repurchases not to exceed 21,000,000 shares. The shares may be authorized, but unissued or reacquired common stock. The number of shares available for issuance under the 2009 Plan will be increased on the first day of each fiscal year beginning with the 2011 fiscal year, in an amount equal to the lesser of (i) 7,000,000 shares, (ii) five percent (5%) of the outstanding shares on the last day of the immediately preceding fiscal year, or (iii) such number of shares determined by the board of directors.

Under the 2009 Plan and the French Sub-Plan, we may grant awards to employees, directors and other service providers. In the case of an incentive stock option granted to an employee who, at the time of the grant, owns stock representing more than 10% of the voting power of all classes of stock, the exercise price shall be no less than 110% of the fair market value per share on the date of grant and expire five years from the date of grant, and options granted to any other employee, the per share exercise price shall be no less than 100% of the fair market value per share on the date of grant. In the case of a non statutory stock option and options granted to other service providers, the per share exercise price shall be no less than 100% of the fair market value per share on the date of grant. Options granted to individuals owning less than 10% of the total combined voting power of all classes of stock generally have a contractual term of seven years and options generally vest over four years.

Stock-based compensation under ASC 718—Effective January 1, 2006, we adopted ASC 718, which requires compensation costs related to share-based transactions, including employee stock options, to be recognized in the financial statements based on fair value. Under ASC 718, the fair value of each option award is estimated on the grant date using the Black-Scholes option pricing model. We determined weighted-average valuation assumptions as follows:

Valuation method—We estimate the fair value of stock options granted using the Black-Scholes valuation model.

Expected Term—The expected term represents the period that our stock-based awards are expected to be outstanding. As we do not have sufficient historical experience for determining the expected term of the stock option awards granted, we have based our expected term on the simplified method available under ASC 718-10 (formerly referred to as Staff Accounting Bulletin 110).

Expected Volatility—The computation of expected volatility for the periods presented is based on the historical and implied stock volatility of comparable companies from a representative peer group selected based on industry and market capitalization data as we did not have sufficient trading history to calculate it directly.

Fair Value of Common Stock—The fair value of the shares of common stock that underlie the stock options we have granted has historically been determined by our board of directors. Because there has been no public market for our common stock, prior to our initial public offering in November 2009, our board has determined the fair value of our common stock at the time of grant of the option by considering a number of objective and subjective factors, our sales of preferred stock to unrelated third parties, our operating and financial performance, the lack of liquidity of our capital stock and trends in the broader network security and computer networking market.

Risk-Free Interest Rate—We base the risk-free interest rate used in the Black-Scholes valuation model on the implied yield available on U.S. Treasury zero-coupon issues with an equivalent remaining term.

Expected Dividend—The expected dividend weighted-average assumption is based on our current expectations about our anticipated dividend policy.

The following table summarizes the weighted-average assumptions relating to our stock options as follows:

At March 31, 2010, total compensation cost related to unvested stock-based awards granted to employees under our stock plans but not yet recognized was $22.5 million, net of estimated forfeitures. This cost is expected to be amortized on a straight-line basis over a weighted-average period of 2.66 years. Future option grants will increase the amount of compensation expense to be recorded in these periods.

The total fair value of awards vested under our stock plans was $3.3 million and $0.8 million for the three months ended March 31, 2010 and March 29, 2009, respectively. The weighted-average fair value of options granted during the first quarter of 2010 was $6.28 per share.

Non-employees—During the quarter ended March 31, 2010, we issued options to purchase 9,400 of common stock, at an exercise price of $16.86 per share, to non-employees in exchange for services. No options were granted to nonemployees in exchange for services during the quarter ended March 29, 2009. These options vest over periods of up to 48 months, and in accordance with ASC 505-50 (formerly referred to as Emerging Issues Task Force Issue No. 96-18, Accounting for Equity Instruments that are Issued to Other Than Employees for Acquiring, or in Conjunction with Selling Goods or Services), we accounted for these options as variable awards. The options were valued using the Black-Scholes option pricing model with the following weighted-average assumptions:

The effective tax rate was 37.3% for the three months ended March 31, 2010, compared with an effective tax rate of 14.9% for the three months ended March 29, 2009. The provision for income taxes for March 31, 2010 is comprised of foreign income taxes, U.S. federal and state taxes, and withholding tax. The provision for income taxes for March 29, 2009 is comprised primarily of foreign income taxes, U.S. federal alternative minimum tax and state income taxes, and withholding tax.

As of March 31, 2010 and December 31, 2009, unrecognized tax benefits determined in accordance with authoritative guidance on accounting for uncertainty in income taxes, approximated $3.4 million for both periods. There were no significant changes in the unrecognized tax benefits for this period. The total amount of unrecognized tax benefits, if recognized, would favorably affect the effective tax rate.

It is our policy to classify accrued interest and penalties related to unrecognized tax benefits in the provision for income taxes. For the three months ended March 31, 2010, interest and penalties related to unrecognized tax benefits were immaterial. We do not expect any material unrecognized tax benefits to expire within the next twelve months.

11. EMPLOYEE BENEFIT PLAN

We have established a 401(k) tax-deferred savings plan (the “401(k) Plan”) which permits participants to make contributions by salary deduction pursuant to Section 401(k) of the Internal Revenue Code. We are responsible for administrative costs of the 401(k) Plan and have made no contributions to the 401(k) Plan since inception.

12. CERTAIN RELATIONSHIPS AND RELATED PARTY TRANSACTIONS

During the three months ended March 29, 2009, we paid compensation of $44,000 to two employees who are directly related to a former board member. This individual ceased being a board member as of October 2009.

In February 2008, we entered into a 23-month non-cancelable facility lease agreement with an entity affiliated with one of our board members. Under the terms of the agreement, in 2008, we paid approximately $284,000 for tenant improvements and $316,000 for a refundable deposit. For the quarter ended March 29, 2009 we paid $249,000 for office rent and operating expenses. The lease expired on December 31, 2009.

13. SEGMENT INFORMATION

ASC 280 (formerly referred to as SFAS No. 131, Disclosures about Segments of an Enterprise and Related Information) establishes standards for reporting information about operating segments. Operating segments are defined as components of an enterprise about which separate financial information is available that is evaluated regularly by the chief operating decision maker in deciding how to allocate resources and in assessing performance. Our chief operating decision maker is our chief executive officer. Our chief executive officer reviews financial information presented on a consolidated basis, accompanied by information about revenue by geographic region for purposes of allocating resources and evaluating financial performance. We have one business activity, and there are no segment managers who are held accountable for operations, operating results and plans for levels or components below the consolidated unit level. Accordingly, we are considered to be in a single reportable segment and operating unit structure.

Business Overview

We are a leading provider of network security appliances and the market leader in UTM network security solutions. We provide broad, integrated and high performance protection against dynamic security threats while simplifying the IT security infrastructure for enterprises, service providers and government entities worldwide. As of March 31, 2010, we had shipped over 550,000 appliances to more than 5,000 channel partners and to more than 90,000 end-customers worldwide, including a majority of the 2009 Fortune Global 100.

Our core UTM product line of FortiGate appliances ships with a set of security and networking capabilities, including firewall, VPN, antivirus, intrusion prevention, Web filtering, antispam and WAN acceleration functionality. We derive a substantial majority of product sales from our FortiGate appliances, which range from the FortiGate-30, designed for small businesses and branch offices, to the FortiGate-5000 series for large enterprises and service providers. On an annual basis for each of the last three fiscal years, sales of FortiGate products have generally been balanced across entry-level (FortiGate-30 to -100 series), mid-range (FortiGate-200 to -800 series) and high-end (FortiGate-1000 to -5000 series) models with each product category representing approximately one-third of FortiGate sales. For the first quarter of 2010 the percentage of our FortiGate related billings from the high-end category was 27% versus 21% for the first quarter of 2009, while the mid-range category decreased from 38% to 33% over the same period, and entry-level remained flat. Our UTM solution also includes our FortiGuard security subscription services, which end-customers can subscribe to in order to obtain access to dynamic updates to the antivirus, intrusion prevention, Web filtering and antispam functionality included in our appliances. End-customers can also choose to purchase FortiCare technical support services for our products. We complement our core FortiGate product line with other appliances and software that offer additional protection from security threats to other critical areas of the enterprise, such as messaging, Web-based traffic and databases, and employee computers or handheld devices. During the current quarter, we extended and enhanced our FortiGate, FortiWeb, FortiMail, and FortiManager appliance families, and also introduced a new family of FortiAP secure access point appliances that address the demand for secure mobility in the enterprise.

We are a global, geographically diversified business, with more than 60% of our total revenue generated outside of the Americas region. For the first quarter of 2010, $23.8 million, or 34%, of our total revenue was generated from the Americas, representing an increase of 24% over the first quarter of 2009. EMEA generated $27.1 million, or 39%, of our total revenue during the current quarter, representing an increase of 30% over the same period of the prior year. APAC generated $18.9 million or 27% of our total revenue during the current quarter, representing an increase of 32% compared to the same period of the prior year. We sell globally in U.S. dollars, while our international expenses are denominated in local currencies.

Total revenue was $69.8 million for the first quarter of 2010, an increase of 29% compared to the first quarter of 2009. Product revenue was $27.1 million, an increase of 40% compared to the first quarter of 2009. Services revenue was $38.6 million, an increase of 22% compared to the first quarter of 2009. Services revenue provides a source of recurring revenue for us, representing about 55% and 58% of total revenue for the first quarter of 2010 and 2009, respectively, and is important to our future revenue and profitability. Ratable product and services revenue was $4.1 million, an increase of 23% compared to the first quarter of 2009.

Our Business Model

Our sales strategy is based on a distribution model whereby we primarily sell our products and services directly to distributors who sell to resellers and service providers, who, in turn, sell to our end-customers. In certain cases, we sell directly to government-focused resellers, large service providers and major systems integrators, who have significant purchasing power and unique customer deployment requirements. Typically, FortiGuard security subscription services and FortiCare technical support services are purchased along with our appliances. We invoice at the time of our sale for the total price of the products and subscription and support services, and the invoice generally becomes payable within 30 to 90 days. We generally recognize product revenue up-front but defer revenue for the sale of new and renewal subscription and support services contracts. We recognize the related services revenue over the service period, which is typically one year from the date the end-customer registers for these services (the date on which the services can first be used by the customer). As a result, our sales of new and renewal services increase our deferred revenue balance, which contributes significantly to our positive cash flow from operations.

Key Metrics

We monitor the key financial metrics set forth below to help us evaluate growth trends, establish budgets, measure the effectiveness of our sales and marketing efforts and assess operational efficiencies. Our total deferred revenue increased by $9.6 million from $201.9 million at December 31, 2009 to $211.5 million at March 31, 2010. Revenue recognized plus the change in deferred revenue from the beginning to the end of the period is a useful metric that management identifies as billings. Billings for services drive deferred revenue, which is an important indicator of the health and visibility of our business, and has historically represented a majority of the quarterly revenue that we recognize. We also ended the first quarter of 2010 with $280.9 million in cash, cash equivalents and investments and have had positive cash flow from operations every fiscal year since 2005. We discuss revenue, gross margin, and the components of operating income and margin below under “—Components of Operating Results,” and we discuss our cash, cash equivalents, and investments under “—Liquidity and Capital Resources.” Deferred revenue and cash flow from operations are discussed immediately below the table.

(2) The increase in total deferred revenue is the change from the beginning of the period to the end of the period.
(3) Free cash flow is a non-GAAP financial measure, which we define as cash flow from operations minus capital expenditures, as further described below.

Deferred revenue. Our deferred revenue consists of amounts that have been invoiced but that have not yet been recognized as revenue. The majority of our deferred revenue balance consists of the unamortized portion of services revenue from subscription and support service contracts. We monitor our deferred revenue balance because it represents a significant portion of revenue to be recognized in future periods. We also assess the increase in our deferred revenue balance plus revenue we recognized in a particular period as a measure of our sales activity for that period.

Cash flow from operations. We monitor cash flow from operations as a measure of our overall business performance. Our cash flow from operations is driven in large part by advance payments for both new and renewal contracts for subscription and support services. Monitoring cash flow from operations enables us to analyze our financial performance without the non-cash effects of certain items such as depreciation, amortization and stock-based compensation expenses, thereby allowing us to better understand and manage the cash needs of our business. Our cash flow from operations was $21.8 million in the first quarter of 2010 and $15.6 million in the first quarter of 2009. In the first quarter of 2010, free cash flow (a non-GAAP measure, described in the “Non-GAAP Financial Measures” below) was $20.8 million, compared to $12.9 million in the first quarter of 2009.

Non-GAAP Financial Measures

To supplement our condensed consolidated financial statements presented in accordance with U.S. GAAP, we consider certain financial measures that are not prepared in accordance with GAAP, including non-GAAP gross margin, non-GAAP income from operations and operating margin, non-GAAP operating expenses, non-GAAP net income and free cash flow. These non-GAAP measures are not based on any standardized methodology prescribed by GAAP and are not necessarily comparable to similar measures presented by other companies. Non-GAAP gross margin is gross margin as reported on our condensed consolidated statements of operations, excluding the impact of stock-based compensation expense, which is a non-cash charge. Non-GAAP income from operations is operating income, as reported on our condensed consolidated statements of operations, excluding the impact of stock-based compensation expense. Non-GAAP operating margin is non-GAAP income from operations divided by revenue. Non-GAAP operating expenses exclude the impact of stock-based compensation expense. Non-GAAP net income is net income plus stock-based compensation expense, less the related tax effects. Free cash flow, an alternative non-GAAP measure of liquidity, is defined as net cash provided by operating activities less capital expenditures.

We believe that these non-GAAP financial measures are appropriate to enhance an overall understanding of our past financial performance, as they help illustrate underlying trends in our business that could otherwise be masked by the effect of the expenses that we exclude in these non-GAAP financial measures. Furthermore, we use many of these measures to establish budgets and operational goals for managing our business and evaluating our performance. We believe that the expenses that we exclude in these non-GAAP financial measures are not reflective of these underlying business trends or useful measures for determining our operational performance and overall business strategy. By excluding these expenses, we believe that our management and investors can better compare our recurring core business operating results over multiple periods.

These non-GAAP financial measures should not be considered in isolation from, or as a substitute for, financial information prepared in accordance with GAAP. There are a number of limitations related to the use of these non-GAAP financial measures versus the nearest GAAP equivalent of these financial measures. First, these non-GAAP financial measures exclude certain recurring, non-cash charges such as stock-based compensation expense. Stock-based compensation has been, and will continue to be for the foreseeable future, a significant recurring expense in our business and is an important part of our employees’ compensation that impacts their performance. Second, the expenses that we exclude in our calculation of these non-GAAP financial measures may differ from the expenses, if any, that our peer companies may exclude when they report their results of operations. We compensate for these limitations by providing the nearest GAAP equivalents of these non-GAAP financial measures and describing these GAAP equivalents in our Results of Operations below.

The following tables reconcile GAAP gross margin, income from operations, operating margin, certain operating expenses and net income as reported on our condensed consolidated statements of operations to non-GAAP gross margin, non-GAAP income from operations, non-GAAP operating margin, certain non-GAAP operating expenses and non-GAAP net income for the first fiscal quarters of 2010 and 2009.

Components of Operating Results

Revenue

We derive our revenue from sales of our products and subscription and support services. We recognize our revenue in accordance with the guidance in ASC 985-605-25 (formerly referred to as Statement of Position, or SOP 97-2, Software Revenue Recognition and SOP 98-9, Modification of SOP 97-2, Software Revenue Recognition, With Respect to Certain Transactions) which is discussed in further detail in “—Critical Accounting Policies and Estimates—Revenue Recognition” below. According to ASC 985-605-25, revenue is recognized when persuasive evidence of an arrangement exists, delivery has occurred, the price is fixed or determinable and collectability is probable.

Our total revenue is comprised of the following:

•

Product revenue. Product revenue is generated from sales of our appliances and software. The substantial majority of our product revenue has been generated by our FortiGate line of appliances, and we do not expect this to change in the foreseeable future. Product revenue also includes revenue derived from sales of FortiManager, FortiAnalyzer, FortiSwitch, FortiMail, FortiDB, FortiWeb, FortiAP and FortiScan appliances, and our FortiClient and virtual domain, or VDOM, software. We generally recognize revenue for products sold to distributors through the “sell-in” method upon shipment to the distributor and, for “sell-through” distributors, upon sale to their end-customer. As a percentage of total revenue, we expect our product revenue may vary from quarter-to-quarter based on seasonal and cyclical factors discussed below under “—Quarterly Results of Operations” but generally may remain at comparable levels or decline modestly, as services revenue becomes a larger portion of our business as we renew existing services contracts and expand our customer base.

•

Services revenue. Services revenue is generated primarily from FortiCare technical support services for software updates, maintenance releases and patches, Internet access to technical content, telephone and Internet access to technical support personnel and hardware support and FortiGuard security subscription services related to antivirus, intrusion prevention, Web filtering and antispam updates. We recognize revenue from subscription and support services over the service performance period. Our typical contractual support and subscription term is one year from the date of registration. We also generate a small portion of our revenue from professional services and training services, and we recognize this revenue as service is provided. As a percentage of total revenue, we expect our services revenue to remain at comparable levels or increase as we renew existing services contracts and expand our customer base.

•

Ratable product and services revenue. Ratable product and services revenue is generated from sales of our products and services in cases where the fair value of the services being provided cannot be segregated from the value of the entire sale. In these cases, the value of the entire sale is deferred and recognized ratably over the life of the service performance period. See “—Critical Accounting Policies and Estimates—Revenue Recognition.” In fiscal 2008 and fiscal 2009, ratable product and service revenue represented approximately six percent of total revenue and we do not expect this percentage to change significantly in the near future.

Cost of revenue

Our total cost of revenue is comprised of the following:

•

Cost of product revenue. A substantial majority of the cost of product revenue consists of third-party manufacturing costs. Our cost of product revenue also includes product testing costs, write-offs for excess and obsolete inventory, royalty payments, amortization and any impairment of applicable acquired intangible assets, warranty costs, shipping and allocated facilities costs, stock-based compensation costs, and personnel costs associated with logistics and quality control. Personnel costs include cash-based personnel costs such as salaries, benefits and bonuses. Royalties reflect amounts related to Trend Micro since 2006, which Trend Micro claims are owed through 2015, as discussed in “Item 1—Legal Proceedings.” For fiscal 2008 and fiscal 2009, this royalty represented approximately one percent of total revenue and we do not expect this percentage to increase substantially in the foreseeable future.

•

Cost of services revenue. Cost of services revenue is primarily comprised of cash-based personnel costs associated with our FortiGuard Labs team and our technical support, professional services and training teams, as well as depreciation, supplies, data center, data communications, facility-related costs and stock-based compensation costs. We expect our cost of services revenue will increase as we continue to invest in subscription and support services to meet the needs of our growing customer base.

•

Cost of ratable product and services revenue. Cost of ratable product and services revenue is comprised primarily of deferred product costs and services-related costs.

Gross profit. Gross profit as a percentage of revenue, or gross margin, has been and will continue to be affected by a variety of factors, including the average sales price of our products, any excess inventory write-offs, manufacturing costs, the mix of products sold and the mix of revenue between products and services. We believe our overall gross margin for the near term may decline modestly or be relatively flat compared to that achieved in fiscal 2009 as we do not anticipate in the near term any significant change in the factors positively influencing gross margin.

Services revenue has increased as a percentage of total revenue since inception, and this trend has had a positive effect on our total gross margin given the higher services gross margins compared to product gross margins. Our services gross margins have been increasing, but we do not expect these margins to increase, in a meaningful way, in the future as we continue to invest in our support infrastructure.

Operating expenses. Our operating expenses consist of research and development, sales and marketing and general and administrative expenses. Personnel costs are the most significant component of operating expenses and consist of cash-based personnel costs such as salaries, benefits, bonuses and, with regard to the sales and marketing expense, sales commissions. They also include non-cash charges, specifically, stock-based compensation. We expect personnel costs to continue to increase in absolute dollars as we hire new employees.

•

Research and development. Research and development expense consists primarily of cash-based personnel costs. Additional research and development expenses include ASIC and system prototypes and certification-related expenses, depreciation of capital equipment, facility-related expenses and stock-based compensation expenses. The majority of our research and development is focused on both software development and the ongoing development of our hardware platform. We record all research and development expenses as incurred, except for capital equipment which is depreciated over time. Our development teams are primarily located in Canada, China, and California. We expect our spending for research and development to increase in absolute dollars but intend for research and development expenses to remain comparable to recent periods as a percentage of total revenue.

•

Sales and marketing. Sales and marketing expense is the largest component of our operating expenses and primarily consists of cash-based personnel costs. Additional sales and marketing expenses include stock-based compensation, promotional and other marketing expenses, travel, depreciation of capital equipment and facility-related expenses. We intend to hire additional personnel focused on sales and marketing and expand our sales and marketing efforts worldwide in order to add new customers and increase penetration within our existing customer base. Accordingly, we expect sales and marketing expenses to increase in absolute dollars and to continue to be our largest operating expense.

•

General and administrative. General and administrative expenses consist of cash-based personnel costs as well as professional fees, stock-based compensation, depreciation of capital equipment and software, and facility-related expenses. General and administrative personnel include our executive, finance, human resources, information technology and legal organizations. Our professional fees principally consist of outside legal, auditing, accounting, information technology and other consulting costs. We expect that general and administrative expense will increase in absolute dollars as we hire additional personnel, make improvements to our information technology infrastructure and incur significant additional costs for the compliance requirements of operating as a public company, including the costs associated with SEC reporting, Sarbanes-Oxley Act compliance and insurance.

Interest income. Interest income consists of income earned on our cash, cash equivalents and investments. We have historically invested our cash in money market funds, commercial paper, corporate debt securities and U.S. government debt securities.

Other income (expense),net. Other income (expense), net consists primarily of foreign exchange gains and losses. Foreign exchange gains and losses relate to transactions denominated in currencies other than the functional currency of the associated entity.

Provision for income taxes. Our income tax provision is based on our worldwide estimated annualized effective tax rate. We are subject to tax in the United States as well as other tax jurisdictions or countries in which we conduct business. Earnings from our non-U.S. activities are subject to local country income tax and may be subject to current U.S. income tax. Our effective tax rates differ from the statutory rate primarily due to foreign income subject to different tax rates than the U.S., research and development tax credits, withholding tax, and nondeductible compensation.

Critical Accounting Policies and Estimates

Our discussion and analysis of our financial condition and results of operations are based upon our financial statements, which have been prepared in accordance with U.S. GAAP. These principles require us to make estimates and judgments that affect the reported amounts of assets, liabilities, revenue and expenses, cash flow and related disclosure of contingent assets and liabilities. Our estimates include those related to revenue recognition, stock-based compensation, valuation of inventory, warranty liabilities and accounting for income taxes. We base our estimates on historical experience and on various other assumptions that we believe to be reasonable under the circumstances. Actual results may differ from these estimates. To the extent that there are material differences between these estimates and our actual results, our future financial statements will be affected.

We believe the accounting policies and estimates discussed under Item 7, “Management’s Discussion and Analysis of Financial Condition and Results of Operations” in our Annual Report on Form 10-K for the fiscal year ended December 31, 2009 reflect our more significant judgments and estimates used in the preparation of the condensed consolidated financial statements. There have been no material changes to the critical accounting policies and estimates as filed in such report.

Total revenue	$	69,795	100.0	%	$	54,194	100.0	%	$	15,601	28.8	%

Total revenue increased $15.6 million, or 28.8%, in the first quarter of 2010 compared to the first quarter of 2009, partly due to growth in product revenue. The APAC and EMEA regions contributed the largest portion of this growth. Product revenue increased $7.8 million, or 40.3%, compared to the first quarter of 2009. The increase in product revenue was primarily driven by higher product sales volume across all regions with a comparable product mix and average sales price. Services revenue increased $7.1 million, or 22.3%, in the first quarter of 2010 compared to the first quarter of 2009 due to recognition of revenue from our growing deferred revenue balance consisting of subscription and support contracts sold to a larger customer base. The growth in ratable product and services revenue was due to a slight decrease in the weighted-average service period over which such revenue was recognized, due to a decrease in the average contractual term of support contracts for arrangements in which we recognized product and services revenue ratably over the performance period.

Total gross margin		72.2			73.0			(0.8	)

Total gross margin decreased 0.8 percentage points in the first quarter of 2010 primarily due to a higher mix of product revenue compared to the first quarter of 2009. Product gross margin increased 1.3 percentage points in the first quarter of 2010 compared to 2009 primarily due to flat warranty-related return costs combined with higher product revenue. The 0.7 percentage point decrease in services gross margin was primarily due to investments in our support organization. Services cost increased by $1.4 million primarily due to $0.8 million of higher cash-based personnel costs, a significant portion of which related to headcount increases in our Americas support organization. Travel, depreciation, and occupancy-related costs increased a combined $0.4 million and stock-based compensation increased $0.1 million. Ratable product and services gross margin was comparable to the prior period.

Research and development expense

Research and development expense increased $2.1 million, or 20.8%, in the first quarter of 2010 compared to the first quarter of 2009 primarily due to an increase of $1.6 million in cash-based personnel costs as a result of increased headcount to support continued enhancements of our products. We also had an increase of $0.2 million in stock-based compensation expense. An 18% increase in the Canadian dollar exchange rate against the US dollar significantly contributed to the increase in research and development expense.

Sales and marketing expense

Sales and marketing expense increased $5.0 million, or 22.8%, in the first quarter of 2010 compared to the first quarter of 2009 primarily due to increased cash-based personnel costs of $4.1 million based on increased headcount primarily in the U.S., a $0.5 million increase in promotional and other marketing-related expenses and a $0.2 million increase in stock-based compensation expense. As a percentage of revenue, sales and marketing expenses decreased 1.9 percentage points.

General and administrative expense

In the first quarter of 2010, general and administrative expense increased $0.4 million, or 8.3%, compared to the first quarter of 2009. The increase was primarily due to increased cash-based personnel costs of $0.3 million, and a $0.1 million increase in stock-based compensation.

The $0.4 million decrease in interest income in the first quarter of 2010 compared to the first quarter of 2009 was due to lower interest rates earned, despite higher balances of cash, cash equivalents and investments. The decrease in other income (expense), net for the first quarter of 2010 when compared to the first quarter of 2009 was the result of a foreign exchange gain in 2009.

The effective tax rate was 37.3% for the quarter ended March 31, 2010, compared with an effective tax rate of 14.9% for the quarter ended March 31, 2009. The provision for income taxes for March 31, 2010 is comprised of foreign income taxes, U.S. federal and state taxes, and withholding tax. The provision for income taxes for the quarter ended March 31, 2009 is comprised primarily of foreign income taxes, U.S. federal alternative minimum tax and state income taxes, and withholding tax. The increase in the effective tax rate for the quarter ended March 31, 2010, compared with the same period in the prior year, is attributable to the use of net operating loss carryforwards to reduce our tax rate in 2009, prior to releasing our valuation allowance at the end of fiscal 2009, as well as the fact that the U.S. research and development tax credit expired on December 31, 2009 and has not yet been extended by the U.S. Congress. The valuation allowance was released at the end of fiscal 2009.

At March 31, 2010, our cash, cash equivalents, and short-term investments of $248.2 million were held for working-capital purposes and were invested primarily in money market funds, commercial paper, corporate debt securities and U.S. government debt securities. We do not enter into investments for trading or speculative purposes. We believe that our cash from operations together with existing cash and cash equivalents will be sufficient to meet our anticipated cash needs for at least the next twelve months. Our future capital requirements will depend on many factors including our growth rate, the timing and extent of spending necessary to support development efforts, the expansion of sales and marketing activities, the introduction of new and enhanced products and services offerings, the costs to ensure access to adequate manufacturing capacity and the continuing market acceptance of our products. In the event that additional financing is required from outside sources, we may not be able to raise it on terms acceptable to us or at all. If we are unable to raise additional capital when desired, our business, operating results and financial condition would be adversely affected.

Operating Activities

In the first quarter of 2010, operating activities provided $21.8 million in cash as a result of net income of $4.2 million, reduced by non-cash items such as an excess tax benefit from employee stock option plans of $0.8 million, increased by stock-based compensation amounts of $2.1 million, depreciation and amortization amounts of $1.4 million, and amortization of investment premiums of $1.1 million. Changes in operating assets and liabilities provided $13.8 million in cash. Sources of cash totaled $15.4 million and were related to a $9.6 million increase in deferred revenue which was attributable primarily to increased sales of our subscription and support services, a $0.4 million decrease in deferred cost of revenue, a $3.2 million decrease in accounts receivable, a $0.8 million increase in accrued payroll and compensation primarily related to increased headcount, and a $1.4 million increase in taxes payable. Uses of cash totaled $1.6 million and were related to a $0.5 million increase in prepaid expenses and other assets, and a $1.1 million decrease in accounts payable and accrued liabilities, respectively, related to timing of payments.

In the first quarter of 2009, operating activities provided $15.6 million in cash as a result of net income of $3.8 million, increased by non-cash items such as depreciation and amortization amounts of $1.4 million and stock-based compensation amounts of $1.6 million. Changes in operating assets and liabilities provided $8.6 million in cash. Sources of cash totaled $12.0 million and were related to a $6.0 million increase in deferred revenue which was attributable to increased sales of our subscription and support services, a $5.5 decrease in accounts receivable, and a $0.3 million increase in accounts payable due to timing of payments. Uses of cash totaled $3.4 million and were related to a $2.2 million decrease in accrued liabilities and accrued payroll and compensation, $0.6 million increase in prepaid expenses and other assets, and $0.3 decrease in income tax payable, related to the timing of payments.

Investing Activities

Our investing activities during the first quarter of 2010 consisted primarily of purchases and sales of investments and capital expenditures. The $61.0 million of cash used by investing activities was due primarily to net purchases of investments of $60.0 million. Additionally, we used cash of $1.0 million for capital expenditures.

Our investing activities during the first quarter of 2009 consisted primarily of purchases and sales of investments and capital expenditures. The $15.1 million of cash used by investing activities was due primarily to net purchases of investments of $12.4 million. Additionally, we used cash of $2.6 million for capital expenditures.

Financing Activities

Our financing activities in the first quarter of 2010 resulted in net cash provided of $1.3 million as a result of receiving proceeds of $1.4 million from the exercise of stock options to purchase our common stock and an excess tax benefit from employee stock option plans of $0.8 million, all partially offset by $0.9 million issuance cost paid in connection with our initial public offering, which had been accrued as of December 31, 2009.

Our financing activities in the first quarter of 2009 resulted in net cash used of $7.3 million as a result of $8.0 million used to repurchase our preferred and common stock, partially offset by proceeds of $0.7 million, as a result of exercises of stock options to purchase our common stock.

(1)	Consists of contractual obligations from non-cancelable office space under operating leases.

(2)	Consists of minimum purchase commitments with independent contract manufacturers.

(3)	Consists of minimum royalties claimed by Trend Micro to be owed, which are subject to dispute. See “Part II: Item 1—Legal Proceedings.”

(4)

No amounts related to ASC 740-10 (FIN 48) are included. As of March 2010, we had approximately $3.4 million of tax liabilities, including interest, related to uncertain tax positions. Because of the high degree of uncertainty regarding the settlement of these liabilities, we are unable to estimate the years in which future cash outflows may occur.

Off-Balance Sheet Arrangements

During the first quarter of 2010, we did not have any relationships with unconsolidated organizations or financial partnerships, such as structured finance or special purpose entities that would have been established for the purpose of facilitating off-balance sheet arrangements or other contractually narrow or limited purposes.

Recent Accounting Pronouncements

See Note 1 of Notes to Condensed Consolidated Financial Statements for recent accounting pronouncements that could have an effect on us.

ITEM 3.

Quantitative and Qualitative Disclosures about Market Risk

Interest Rate Fluctuation Risk

The primary objectives of our investment activities are to preserve principal, provide liquidity and maximize income without significantly increasing risk. Some of the securities we invest in are subject to market risk. This means that a change in prevailing interest rates may cause the principal amount of the investment to fluctuate. To minimize this risk, we maintain our portfolio of cash, cash equivalents, short- and long-term investments in a variety of securities, including commercial paper, money market funds, government and corporate debt securities and certificates of deposit. The risk associated with fluctuating interest rates is limited to our investment portfolio. A 10% decrease in interest rates during the first fiscal quarter of 2010 and 2009 would have resulted in a decrease in our interest income of approximately $27,000 and $71,000, respectively. As of March 31, 2010, our cash, cash equivalents and short- and long- term investments were in money market funds, commercial paper, corporate debt securities and U.S. government debt securities.

Foreign Currency Exchange Risk

Our sales contracts are primarily denominated in U.S. dollars and therefore substantially all of our revenue is not subject to foreign currency risk. However, a substantial portion of our operating expenses incurred outside the U.S. are denominated in foreign currencies and are subject to fluctuations due to changes in foreign currency exchange rates, particularly changes in the Canadian dollar, Euro, and British Pound. Additionally, fluctuations in foreign currency exchange rates may cause us to recognize transaction gains and losses in our condensed consolidated statements of operations. We recognized other expense, net of $(0.3) million in the first quarter of 2010 due to foreign currency transaction losses.

We use foreign exchange forward contracts to partially mitigate the impact of fluctuations in foreign currency rates on certain balance sheet accounts. We do not use these contracts for speculative or trading purposes. These contracts typically have maturities between one and two months, and we record gains and losses from these instruments in other income (expense), net.

Inflation Risk

Our monetary assets, consisting primarily of cash, cash equivalents and short-term investments, are not affected significantly by inflation because they are short-term. We believe the impact of inflation on replacement costs of equipment, furniture and leasehold improvements will not materially affect our operations. The rate of inflation, however, affects our cost of revenue and expenses, such as those for employee compensation, which may not be readily recoverable in the price of products and services offered by us.

ITEM 4.

Controls and Procedures

Evaluation of Disclosure Controls and Procedures

Our management, with the participation of our chief executive officer and chief financial officer, evaluated the effectiveness of our disclosure controls and procedures (as defined in Rules 13a-15(e) or 15d-15(e) under the Securities Exchange Act of 1934, as amended (the “Exchange Act”)) as of March 31, 2010. In designing and evaluating the disclosure controls and procedures, management recognized that any controls and procedures, no matter how well designed and operated, can provide only reasonable assurance of achieving the desired control objectives. In addition, the design of disclosure controls and procedures must reflect the fact that there are resource constraints and that management is required to apply its judgment in evaluating the benefits of possible controls and procedures relative to their costs.

Based on that evaluation, our chief executive officer and chief financial officer concluded that our disclosure controls and procedures were effective as of March 31, 2010 to provide reasonable assurance that information we are required to disclose in reports that we file or submit under the Exchange Act is recorded, processed, summarized and reported within the time periods specified in the Securities and Exchange Commission rules and forms, and that such information is accumulated and communicated to our management, including our chief executive officer and chief financial officer, as appropriate, to allow timely decisions regarding required disclosure.

Changes in Internal Control over Financial Reporting

There were no changes in our internal control over financial reporting (as defined in Rules 13a-15(f) or 15d-15(f) under the Exchange Act) during our first fiscal quarter that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

Part II

ITEM 1.

Legal Proceedings

In May 2004, Trend Micro Incorporated filed a complaint against us alleging that we infringed a Trend Micro patent related to antivirus software. In January 2006, we settled the lawsuit with Trend Micro. Pursuant to the settlement and license agreement, we initially paid Trend Micro $15.0 million. The settlement and license agreement provides for additional quarterly royalty payments, not expected to exceed 1% of our total revenue each quarter, through 2015. In November 2008, we filed a complaint against Trend Micro in the United States District Court for the Northern District of California alleging, among other claims, that the patents that are the basis for the ongoing royalty payments are invalid and consequently that we have no contractual obligation to pay the royalties. Trend Micro moved to dismiss the case, and, in June 2009, the court dismissed the case without prejudice on procedural grounds, and we appealed the dismissal in July 2009. Based on the dispute, we have ceased paying royalties under the settlement and license agreement. In August 2009, Trend Micro filed a complaint against us in the Superior Court of the State of California for Santa Clara County alleging breach of contract and seeking a declaratory judgment that we are obligated to make certain royalty payments to Trend Micro. In December 2009, we withdrew our appeal of the June 2009 dismissal by the United States District Court for the Northern District of California and filed a new complaint against Trend Micro in the United States District Court for the Northern District of California alleging, among other claims, that the patents that are the basis for the ongoing royalty payments are invalid and consequently that we have no contractual obligation to pay royalties. We have continued to accrue expense based on the quarterly royalties provided for in the settlement and license agreement. In February 2010, Trend Micro filed demurrers in the state Superior Court action regarding Fortinet’s affirmative defenses that Fortinet has no obligation to pay royalties because the Trend Micro patents are invalid or unenforceable. In March 2010, Trend Micro filed a motion to dismiss our new complaint that we filed in the United States District Court for the Northern District of California. On May 3, 2010, the state court denied Trend Micro’s demurrer in its entirety. On May 12, 2010, the United States District Court for the Northern District of California denied Trend Micro’s motion to dismiss without prejudice and stayed the action before that court pending the conclusion of the state court action.

In January 2009, we filed a complaint against Palo Alto Networks, Inc., in the United States District Court for the Northern District of California alleging, among other claims, patent infringement. In September 2009, Palo Alto Networks filed a counterclaim against us alleging patent infringement. In May 2009, Enhanced Security Research, LLC, or ESR, a non-practicing entity, filed a complaint in the United States District Court for the District of Delaware alleging patent infringement by us and other defendants. In August 2009, ESR filed a substantially similar complaint against us in the same court alleging infringement of the same patents. In September 2009, Deep Nines, Inc. filed, but did not serve us with, a complaint against us in the United States District Court for the Eastern District of Texas alleging that our products infringe certain of their patents. The Palo Alto Networks and ESR cases are currently at an early stage of the litigation process. The Deep Nines case has not yet been served.

In April 2010, an individual and former stockholder of Fortinet filed a class action lawsuit against us in the Superior Court of the State of California for the County of Los Angeles alleging violation of various California Corporate Code sections and related tort claims alleging misrepresentation and breach of fiduciary duty regarding the 2009 repurchase by Fortinet of its stock while we were a privately-held company, as discussed in “Note 8—Stockholders’ Equity” above.

In addition to the above matters, we are subject to other litigation in the ordinary course of business. The results of legal proceedings cannot be predicted with certainty. If we do not prevail in any of these legal matters, our operating results may be materially affected. At this time, we are unable to estimate the financial impact these actions will likely have on the company.

ITEM 1A.

Risk Factors

Investing in our common stock involves a high degree of risk. You should carefully consider the following risks and all other information contained in this 10-Q, including our condensed consolidated financial statements and the related notes, before investing in our common stock. The risks and uncertainties described below are not the only ones we face. Additional risks and uncertainties that we are unaware of, or that we currently believe are not material, also may become important factors that affect us. If any of the following risks materialize, our business, financial condition and results of operations could be materially harmed. In that case, the trading price of our common stock could decline, and you may lose some or all of your investment.

Risks Related to Our Business

Our quarterly operating results are likely to vary significantly and be unpredictable.

Our operating results have historically varied from period to period, and we expect that they will continue to do so as a result of a number of factors, many of which are outside of our control and may be difficult to predict, including:

•

the level of demand for our products and services, and the timing of channel partner and end-customer orders;

•

the timing of shipments, which may depend on many factors such as inventory levels and logistics, our ability to ship new products on schedule and accurately forecast inventory requirements, and possible increases in the time for the manufacture of products;

•

the mix of products sold, the mix of revenue between products and services and the degree to which products and services are bundled and sold together for a package price;

•

the budgeting cycles and purchasing practices of our channel partners and end-customers;

•

seasonal buying patterns of our end-customers;

•

the timing of revenue recognition for our sales, which may be affected by both the mix of sales by our “sell-in” versus our “sell-through” channel partners, and by the extent to which we bring on new distributors;

•

the accuracy and timing of point of sale reporting by our sell-through distributors, which impacts our ability to recognize revenue;

•

the level of perceived threats to network security, which may fluctuate from period to period;

•

changes in end-customer, distributor or reseller requirements or market needs;

•

changes in the growth rate of the network security or UTM markets;

•

the timing and success of new product and service introductions by us or our competitors or any other change in the competitive landscape of our industry, including consolidation among our competitors or end-customers;

•

deferral of orders from end-customers in anticipation of new products or product enhancements announced by us or our competitors;

•

decisions by potential end-customers to purchase network security solutions from larger, more established security vendors or from their primary network equipment vendors;

•

price competition;

•

changes in customer renewal rates for our services;

•

changes in the length of services contracts sold;

•

insolvency or credit difficulties confronting our customers, affecting their ability to purchase or pay for our products and services;

•

any disruption in our channel or termination of our relationship with important channel partners;

•

insolvency or credit difficulties confronting our key suppliers, which could disrupt our supply chain;

•

general economic conditions, both domestically and in our foreign markets;

•

future accounting pronouncements or changes in our accounting policies; and

•

increases or decreases in our expenses caused by fluctuations in foreign currency exchange rates, as a significant portion of our expenses are incurred and paid in currencies other than the U.S. dollar.

Any one of the factors above or the cumulative effect of some of the factors referred to above may result in significant fluctuations in our quarterly operating results, including both financial statement results and other important metrics. This variability and unpredictability could result in our failing to meet our revenue and other expected metrics and our other operating results expectations or those of securities analysts or investors for any period. If we fail to meet or exceed such expectations for these or any other reasons, the market price of our shares could fall substantially and we could face costly lawsuits, including securities class action suits. In addition, a significant percentage of our operating expenses are fixed in nature and based on forecasted revenue trends. Accordingly, in the event of revenue shortfalls, we are generally unable to mitigate the negative impact on margins in the short term.

Reliance on a concentration of shipments at the end of the quarter could cause our revenue to fall below expected levels.

As a result of customer-buying patterns and the efforts of our sales force and channel partners to meet or exceed quarterly quotas, historically we have received a substantial portion of a quarter’s sales orders and generated a substantial portion of a quarter’s revenue during the last two weeks or last days of the quarter. If expected revenue at the end of any quarter is delayed for any reason, including the failure of anticipated purchase orders to materialize, our or our logistics partners’ inability to ship products prior to quarter-end to fulfill purchase orders received near the end of the quarter, our failure to manage inventory properly in a way to meet demand, or our inability to release new products on schedule, our revenue for that quarter could fall below our expectations or those of securities analysts and investors, resulting in a decline in our stock price.

We have a history of losses and may not maintain profitability, and our revenue growth may not continue.

We have incurred net losses in most fiscal years since our inception, including net losses of $21.8 million in fiscal 2007, $5.3 million in fiscal 2006, $14.2 million in fiscal 2005 and $59.0 million in fiscal 2004. As a result, we had an accumulated deficit of $55.8 million at March 31, 2010. Although we were profitable in fiscal 2008, fiscal 2009, and the first quarter of fiscal 2010, we may not be able to sustain profitability in future periods if we fail to increase revenue or deferred revenue, manage our cost structure, or are subject to unanticipated liabilities. Revenue growth may slow or revenue may decline for a number of possible reasons, including slowing demand for our products or services, increasing competition, a decrease in the growth of our overall market, or if we fail for any reason to continue to capitalize on growth opportunities. Any failure by us to maintain profitability and continue our revenue growth could cause the price of our common stock to materially decline.

We rely significantly on revenue from subscription and support services which may decline, and, because we recognize revenue from subscriptions and support services over the term of the relevant service period, downturns or upturns in sales are not immediately reflected in full in our operating results.

Our services revenue accounted for 55% and 58% of our total revenue for the first quarters of fiscal 2010 and 2009, respectively. Sales of new or renewal subscription and services contracts may decline and fluctuate as a result of a number of factors, including end-customers’ level of satisfaction with our products and services, the prices of our products and services, the prices of products and services offered by our competitors or reductions in our customers’ spending levels. If our sales of new or renewal subscription and services contracts decline, our revenue and revenue growth may decline and our business will suffer. In addition we recognize subscription and service revenue monthly over the term of the relevant service period, which is typically one year but has been as long as five years. As a result, much of the revenue we report each quarter is the recognition of deferred revenue from subscription and services contracts entered into during previous quarters. Consequently, a decline in new or renewed subscription or service contracts in any one quarter will not be fully reflected in revenue in that quarter, but will negatively affect our revenue in future quarters. Accordingly, the effect of significant downturns in new or renewed sales of our subscriptions or services is not reflected in full in our results of operations until future periods. Our subscription and service revenue also makes it difficult for us to rapidly increase our revenue through additional service sales in any period, as revenue from new and renewal service contracts must be recognized over the applicable service period. Furthermore increases in the average term of services contracts would result in revenue for services contracts being recognized over longer periods of time.

Managing inventory of our products and product components is complex. Insufficient inventory may result in lost sales opportunities or delayed revenue, while excess inventory may harm our gross margins.

Our channel partners may increase orders during periods of product shortages, cancel orders if their inventory is too high, return product or take advantage of price protection (if any), or delay orders in anticipation of new products. They also may adjust their orders in response to the supply of our products and the products of our competitors that are available to them and in response to seasonal fluctuations in end-customer demand. Furthermore if the time required to manufacture certain products or ship products increases for any reason, this could result in inventory shortfalls. Management of our inventory is further complicated by the significant number of different products that we sell and the fact that we sell models that must meet regulatory requirements, such as the European Union’s Restriction of the Use of Certain Hazardous Substances in Electrical and Electronic Equipment Directive, or the EU RoHS.

In addition, for those channel partners that have rights of return, inventory held by such channel partners affects our results of operations. Our inventory management systems and related supply chain visibility tools may be inadequate to enable us to effectively manage inventory. Inventory management remains an area of focus as we balance the need to maintain inventory levels that are sufficient to ensure competitive lead times against the risk of inventory obsolescence because of rapidly changing technology and customer requirements. If we ultimately determine that we have excess inventory, we may have to reduce our prices and write-down inventory, which in turn could result in lower gross margins. For example, in the third and fourth quarters of fiscal 2007 we had excess inventory, resulting in significant inventory write-offs. Alternatively, insufficient inventory levels, may lead to shortages that result in delayed revenue or loss of sales opportunities altogether as potential end-customers turn to competitors’ products that are readily available. If we are unable to effectively manage our inventory and that of our distribution partners, our results of operations could be adversely affected.

We rely on third-party channel partners to generate substantially all of our revenue. If our partners fail to perform, our ability to sell our products and services will be limited, and, if we fail to optimize our channel partner model going forward, our operating results will be harmed.

Substantially all of our revenue is generated through sales by our channel partners, which include distributors and resellers. We depend upon our channel partners to generate sales opportunities and manage the sales process. To the extent our channel partners are unsuccessful in selling our products, or we are unable to enter into arrangements with, and retain a sufficient number of high quality channel partners in each of the regions in which we sell products, and keep them motivated to sell our products, our ability to sell our products and operating results will be harmed. The termination of our relationship with any important channel partner may also adversely impact our sales and operating results.

We provide sales channel partners with specific programs to assist them in selling our products, but there can be no assurance that these programs will be effective. In addition, our channel partners may be unsuccessful in marketing, selling and supporting our products and services. Our channel partners generally do not have minimum purchase requirements. They may also market, sell and support products and services that are competitive with ours, and may devote more resources to the marketing, sales and support of such products. They may have incentives to promote our competitors’ products to the detriment of our own. They may cease selling our products altogether. We cannot assure you that we will retain these channel partners or that we will be able to secure additional or replacement partners. The loss of one or more of our significant channel partners or the failure to obtain and ship a number of large orders each quarter through them could harm our operating results. During fiscal 2007, 2008, and 2009, Alternative Technology, Inc., a subsidiary of Arrow Electronics, Inc., was our most significant channel partner, accounting for 12% of our total revenue in each of the periods. During the first quarter of 2010, Alternative Technology, Inc. accounted for 11% of our total revenue. Any new sales channel partner will require extensive training and may take several months or more to achieve productivity. Our channel partner sales structure could subject us to lawsuits, potential liability and reputational harm if, for example, any of our channel partners misrepresent the functionality of our products or services to end-customers or our channel partners violate laws or our corporate policies. If we fail to manage existing sales channels, our business will be seriously harmed.

If we are not successful in continuing to execute our strategy to increase our sales to larger end-customers, our results of operations may suffer.

An important part of our growth strategy is to increase sales of our products to large enterprises, service providers and government entities. Sales to enterprises, service providers and government entities involve risks that may not be present (or that are present to a lesser extent) with sales to small-to-mid-sized entities. These risks include:

•

increased competition from larger competitors, such as Cisco Systems, Inc., Check Point Software Technologies Ltd., McAfee, Inc. and Juniper Networks, Inc., that traditionally target enterprises, service providers and government entities and that may already have purchase commitments from those end-customers;

•

increased purchasing power and leverage held by large end-customers in negotiating contractual arrangements with us;

•

more stringent requirements in our support service contracts, including stricter support response times, and increased penalties for any failure to meet support requirements; and

•

longer sales cycles and the associated risk that substantial time and resources may be spent on a potential end-customer who elects not to purchase our products and services.

Large enterprises, service providers and government entities often undertake a significant evaluation process that results in a lengthy sales cycle, in some cases over 12 months. Although we have a channel sales model, our sales representatives typically engage in direct interaction with our distributors and resellers in connection with sales to larger end-customers. Due to the lengthy nature, the size and scope, and stringent requirements of these evaluations, we typically provide evaluation products to these customers. We may spend substantial time, effort and money in our sales efforts without being successful in producing any sales. If we are unsuccessful in converting these evaluations into sales, we may experience an increased inventory of used products and potentially increased write-offs. In addition, product purchases by enterprises, service providers and government entities are frequently subject to budget constraints, multiple approvals, and unplanned administrative, processing and other delays. Finally, enterprise, service providers and government entities typically have longer implementation cycles; require greater product functionality and scalability and a broader range of services, including design services; demand that vendors take on a larger share of risks; sometimes require acceptance provisions that can lead to a delay in revenue recognition; and expect greater payment flexibility from vendors. All these factors can add further risk to business conducted with these customers. If sales expected from a large end-customer for a particular quarter are not realized in that quarter or at all, our business, operating results and financial condition could be materially and adversely affected.

The average sales prices of our products may decrease, which may reduce our gross profits.

The average sales prices for our products may decline for a variety of reasons, including competitive pricing pressures, discounts we offer, a change in our mix of products, anticipation of the introduction of new products or promotional programs. Competition continues to increase in the market segments in which we participate and we expect competition to further increase in the future, thereby leading to increased pricing pressures. Larger competitors with more diverse product offerings may reduce the price of products that compete with ours in order to promote the sale of other products or may bundle them with other products. Furthermore, we anticipate that the average sales prices and gross profits for our products will decrease over product life cycles. We cannot assure you that we will be successful in developing and introducing new offerings with enhanced functionality on a timely basis, or that our product offerings, if introduced, will enable us to maintain our prices and gross profits at levels that will allow us to maintain profitability.

Defects or vulnerabilities in our products or services, the failure of our products or services to prevent a virus or security breach, or misuse of our products could harm our reputation and divert resources.

Because our products and services are complex, they have contained and may contain defects or errors that are not detected until after their commercial release and deployment by our customers. For example, one of our high-end product models has been experiencing a defect in limited deployments. Defects or vulnerabilities may impede or block network traffic or cause our products or services to be vulnerable to electronic break-ins or cause them to fail to help secure networks. Because the techniques used by computer hackers to access or sabotage networks change frequently and generally are not recognized until launched against a target, we may be unable to anticipate these techniques. In addition, defects or errors in our FortiGuard subscription updates or our FortiGate appliances could result in a failure of our FortiGuard services to effectively update end-customers’ FortiGate appliances and thereby leave customers vulnerable to attacks. Furthermore, our solutions may also fail to detect or prevent viruses, worms or similar threats due to a number of reasons such as the evolving nature of such threats and the continual emergence of new threats that we may fail to add to our FortiGuard databases in time to protect our end-customers’ networks. Our FortiGuard or FortiCare data centers and networks may also experience technical failures and downtime, and may fail to distribute appropriate updates, or fail to meet the increased requirements of a growing customer base. Any such technical failure, downtime, or failures in general may temporarily or permanently expose our end-customers’ networks, leaving their networks unprotected against the latest security threats.

An actual or perceived security breach or infection of the network of one of our end-customers, regardless of whether the breach is attributable to the failure of our products or services to prevent the security breach, could adversely affect the market’s perception of our security products. We may not be able to correct any security flaws or vulnerabilities promptly, or at all. Our products may also be misused by end-customers or third parties who obtain access to our products. For example, our products could be used to censor private access to certain information on the Internet. Such use of our products for censorship could result in negative press coverage and negatively affect our reputation, even if we take reasonable measures to prevent any improper shipment of our products or if our products are provided by an unauthorized third-party. Any defects, errors or vulnerabilities in our products, or misuse of our products, could result in:

•

expenditure of significant financial and product development resources in efforts to analyze, correct, eliminate or work-around errors or defects or to address and eliminate vulnerabilities;

•

loss of existing or potential end-customers or channel partners;

•

delayed or lost revenue;

•

delay or failure to attain market acceptance;

•

negative publicity, which will harm our reputation; and

•

litigation, regulatory inquiries or investigations that may be costly and harm our reputation.

Our business and operations have experienced rapid growth, and if we do not appropriately manage any future growth, or are unable to improve our systems and processes, our operating results will be negatively affected.

We have a high volume business that has grown over the last several years. We rely heavily on information technology systems to help manage critical functions such as order processing, revenue recognition, financial forecasts and inventory and supply chain management. However, we have been slow to adopt and implement certain automated functions, like Electronic Data Interchange, which could have a negative impact on our business. For example, a large part of our order processing relies on the manual processing of emails internally and from our customers. Combined with the fact that we may receive a majority of our orders in the last few weeks of any given quarter, a significant interruption in our email service could result in delayed order fulfillment and decreased revenue for that quarter. To manage any future growth effectively, we must continue to improve and expand our information technology and financial infrastructure, operating and administrative systems and controls, and continue to manage headcount, capital and processes in an efficient manner. We may not be able to successfully implement improvements to these systems and processes in a timely or efficient manner. In addition, our systems and processes may not prevent or detect all errors, omissions or fraud. Our failure to improve our systems and processes, or their failure to operate in the intended manner, may result in our inability to manage the growth of our business and to accurately forecast our revenue, expenses and earnings, or to prevent certain losses. Our productivity and the quality of our products and services may be adversely affected if we do not integrate and train our new employees quickly and effectively. Any future growth would add complexity to our organization and require effective coordination throughout our organization. Failure to manage any future growth effectively could result in increased costs and harm our results of operations.

If our estimates or judgments relating to our critical accounting policies are based on assumptions that change or prove to be incorrect, our operating results could fall below expectations of securities analysts and investors, resulting in a decline in our stock price.

The preparation of financial statements in conformity with generally accepted accounting principles requires management to make estimates and assumptions that affect the amounts reported in the condensed consolidated financial statements and accompanying notes. We base our estimates on historical experience and on various other assumptions that we believe to be reasonable under the circumstances, as provided in “Management’s Discussion and Analysis of Financial Condition and Results of Operations” in our Annual Report on Form 10-K for the fiscal year ended December 31, 2009, the results of which form the basis for making judgments about the carrying values of assets and liabilities that are not readily apparent from other sources. Our operating results may be adversely affected if our assumptions change or if actual circumstances differ from those in our assumptions, which could cause our operating results to fall below the expectations of securities analysts and investors, resulting in a decline in our stock price. Significant assumptions and estimates used in preparing our condensed consolidated financial statements include those related to revenue recognition, stock-based compensation, valuation of inventory, warranty liabilities, and accounting for income taxes.

We offer retroactive price protection to certain of our major distributors, and if we fail to balance their inventory with end-customer demand for our products, our allowance for price protection may be inadequate, which could adversely affect our results of operations.

We provide certain of our major distributors with price protection rights for inventories of our products held by them. If we reduce the list price of our products, certain distributors receive refunds or credits from us that reduce the price of such products held in their inventory based upon the new list price. As of March 31, 2010, we estimated that approximately $1.8 million of our products in our distributors’ inventory were subject to price protection. Future credits for price protection will depend on the percentage of our price reductions for the products in inventory and our ability to manage the levels of our major distributors’ inventories. If future price protection adjustments are higher than expected, our future results of operations could be materially and adversely affected.

If we are unable to hire, retain and motivate qualified personnel, our business will suffer.

Our future success depends, in part, on our ability to continue to attract and retain highly skilled personnel. The loss of the services of any of our key personnel, the inability to attract or retain qualified personnel, or delays in hiring required personnel, particularly in engineering and sales, may seriously harm our business, financial condition and results of operations. We have experienced turnover in our management-level personnel. None of our key employees has an employment agreement for a specific term, and any of our employees may terminate their employment at any time. Our ability to continue to attract and retain highly skilled personnel will be critical to our future success. Competition for highly skilled personnel is frequently intense, especially in the locations where we have a substantial presence and need for highly-skilled personnel: the San Francisco Bay Area, Vancouver, Canada and Beijing, China. A large portion of our employee base is substantially vested in significant stock option grants, and the ability to exercise those options and sell their stock may result in a larger than normal turn-over rate. We may not be successful in attracting, assimilating or retaining qualified personnel to fulfill our current or future needs. Also, to the extent we hire personnel from competitors, we may be subject to allegations that they have been improperly solicited or divulged proprietary or other confidential information.

We are dependent on the continued services and performance of our senior management, the loss of any of whom could adversely affect our business, operating results and financial condition.

Our future performance depends on the continued services and continuing contributions of our senior management to execute on our business plan, and to identify and pursue new opportunities and product innovations. The loss of services of senior management, particularly Ken Xie, our Co-founder, President and Chief Executive Officer, Michael Xie, our Co-founder, Vice President of Engineering and Chief Technical Officer, and Ken Goldman, our Vice President and Chief Financial Officer, could significantly delay or prevent the achievement of our development and strategic objectives. In addition, key personnel may be distracted by activities unrelated to our business. The loss of the services, or distraction, of our senior management for any reason could adversely affect our business, financial condition and results of operations.

If we are unable to establish fair value for any undelivered element of a customer order, revenue relating to the entire order will be deferred and recognized over future periods. A delay in the recognition of revenue for a significant portion of our sales in a particular quarter may adversely affect our results of operations.

In the course of our selling efforts, we typically enter into arrangements that require us to deliver a combination of products and services. We refer to each individual product or service as an “element” of the overall arrangement. These arrangements typically require us to deliver particular elements in a future period. As we discuss further in “Note 1—Summary of Significant Accounting Policies—Revenue Recognition”, if we are unable to determine the fair value of any undelivered elements, we are required by generally accepted accounting principles, or GAAP, to defer revenue from the entire arrangement rather than just the undelivered elements. If we are required to defer revenue from the entire arrangement for a significant portion of our product sales, our revenue for that quarter could fall below our expectations or those of securities analysts and investors, adversely affecting our results of operations and resulting in a decline in our stock price.

Adverse economic conditions or reduced information technology spending may adversely impact our business.

Our business depends on the overall demand for information technology and on the economic health of our current and prospective customers. In addition, the purchase of our products is often discretionary and may involve a significant commitment of capital and other resources. We believe the global economic downturn may have adversely affected our total revenue in fiscal 2009. Weak global economic conditions, weak economic conditions in certain geographies, or a reduction in information technology spending regardless of macro-economic conditions, could adversely impact our business, financial condition and results of operations in a number of ways, including longer sales cycles, lower prices for our products and services, higher default rates among our distributors, reduced unit sales and lower or no growth.

Because we depend on several third-party manufacturers to build our products, we are susceptible to manufacturing delays that could prevent us from shipping customer orders on time, if at all, and may result in the loss of sales and customers.

We outsource the manufacturing of our security appliance products to a variety of contract manufacturing partners and original design manufacturing partners.

Our reliance on our third-party manufacturers reduces our control over the manufacturing process, exposing us to risks, including reduced control over quality assurance, product costs and product supply and timing. Any manufacturing disruption by our third-party manufacturers could impair our ability to fulfill orders. If we are unable to manage our relationships with these third-party manufacturers effectively, or if these third-party manufacturers experience delays, increased manufacturing lead-times, disruptions, capacity constraints or quality control problems in their manufacturing operations, or fail to meet our future requirements for timely delivery, our ability to ship products to our customers could be impaired and our business would be seriously harmed.

These manufacturers fulfill our supply requirements on the basis of individual purchase orders. We have no long-term contracts or arrangements with certain of our third-party manufacturers that guarantee capacity, the continuation of particular payment terms or the extension of credit limits. Accordingly, they are not obligated to continue to fulfill our supply requirements, and the prices we are charged for manufacturing services could be increased on short notice. If we are required to change third-party manufacturers, our ability to meet our scheduled product deliveries to our customers would be adversely affected, which could cause the loss of sales and existing or potential customers, delayed revenue or an increase in our costs which could adversely affect our gross margins. Our individual product lines are generally manufactured by only one manufacturing partner. Any production interruptions for any reason, such as a natural disaster, epidemic, capacity shortages, or quality problems, at one of our manufacturing partners would severely affect sales of our product lines manufactured by that manufacturing partner.

Our proprietary FortiASIC, which is the key to the performance of our appliances, is fabricated by contract manufacturers in foundries operated by UMC and Taiwan Semiconductor Manufacturing Corporation, or TSMC. Faraday (using UMC’s foundry) and K-Micro (using TSMC’s foundry) manufacture our ASICs on a purchase order basis, and these foundries do not guarantee any capacity and could reject orders from either Faraday or K-Micro or try to increase pricing. Accordingly, the foundries are not obligated to continue to fulfill our supply requirements, and due to the long lead time that a new foundry would require, we could suffer temporary or long term inventory shortages of our FortiASIC as well as increased costs. Our suppliers may also prioritize orders by other companies that order higher volumes of products. If any of these suppliers materially delays its supply of ASICs or specific product models to us, or requires us to find an alternate supplier and we are not able to do so on a timely and reasonable basis, or if these foundries materially increase their prices for fabrication of our ASICs or specific product models, our business would be harmed.

In addition, our reliance on third-party manufacturers and foundries limits our control over environmental regulatory requirements such as the hazardous substance content of our products and therefore our ability to ensure compliance with the EU RoHS and other similar laws. See “If we fail to comply with environmental requirements, our business, financial condition, operating results and reputation could be adversely affected” for information on the effects of the failure to comply with these laws.

Because some of the key components in our products come from limited sources of supply, we are susceptible to supply shortages or supply changes, which could disrupt or delay our scheduled product deliveries to our customers and may result in the loss of sales and customers.

We and our contract manufacturers currently purchase several key parts and components used in the manufacture of our products from limited sources of supply. We are therefore subject to the risk of shortages in the supply of these components and the risk that component suppliers discontinue or modify components used in our products. We have faced component shortages in the past. Certain of our limited source components for particular appliances and suppliers of those components include: specific types of central processing units from Intel Corporation, Advanced Micro Devices, Inc., RMI Corporation and VIA Technologies, Inc. and network chips from Broadcom Corporation, Marvell Technology Group Ltd. and Intel. The introduction by component suppliers of new versions of their products, particularly if not anticipated by us or our contract manufacturers, could require us to expend significant resources to incorporate these new components into our products. In addition, if these suppliers were to discontinue production of a necessary part or component, we would be required to expend significant resources and time in locating and integrating replacement parts or components from another vendor. Qualifying additional suppliers for limited source parts or components can be time-consuming and expensive.

Our manufacturing partners have experienced increasing lead times for the purchase of components incorporated into our products. Our reliance on a limited number of suppliers involves several additional risks, including:

•

a potential inability to obtain an adequate supply of required parts or components when required;

•

financial or other difficulties faced by our suppliers;

•

infringement or misappropriation of our intellectual property;

•

price increases;

•

failure of a component to meet environmental or other regulatory requirements;

•

failure to meet delivery obligations in a timely fashion; and

•

failure in component quality.

The occurrence of any of these would be disruptive to us and could seriously harm our business. Any interruption or delay in the supply of any of these parts or components, or the inability to obtain these parts or components from alternate sources at acceptable prices and within a reasonable amount of time, would harm our ability to meet our scheduled product deliveries to our distributors, resellers and end-customers. This could harm our relationships with our channel partners and end-customers and could cause delays in shipment of our products and adversely affect our results of operations.

We are exposed to fluctuations in currency exchange rates, which could negatively affect our financial condition and results of operations.

Our sales contracts are primarily denominated in U.S. dollars and therefore substantially all of our revenue is not subject to foreign currency risk. However, a strengthening of the U.S. dollar could increase the real cost of our products to our customers outside of the United States, which could adversely affect our financial condition and results of operations. In addition, a majority of our operating expenses were incurred outside the United States, are denominated in foreign currencies and are subject to fluctuations due to changes in foreign currency exchange rates, particularly changes in the Euro and Canadian dollar. Although we have begun to hedge currency exposures relating to certain balance sheet accounts, we do not currently hedge currency exposures relating to operating expenses incurred outside of the United States, but we may do so in the future. If our attempts to hedge against these risks are not successful, our financial condition and results of operations could be adversely affected.

We generate a majority of revenue from sales to distributors, resellers and end-customers outside of the United States, and we are therefore subject to a number of risks associated with international sales and operations.

We market and sell our products throughout the world and have established sales offices in many parts of the world. Therefore, we are subject to risks associated with having worldwide operations. We are also subject to a number of risks typically associated with international sales and operations, including:

•

economic or political instability in foreign markets;

•

greater difficulty in enforcing contracts, accounts receivable collection and longer collection periods;

•

changes in regulatory requirements;

•

difficulties and costs of staffing and managing foreign operations;

•

the uncertainty of protection for intellectual property rights in some countries;

•

costs of compliance with foreign policies, laws and regulations and the risks and costs of non-compliance with such policies, laws and regulations;

•

costs of complying with U.S. laws and regulations for foreign operations, including the Foreign Corrupt Practices Act, import and export control laws, tariffs, trade barriers, and economic sanctions;

•

other regulatory or contractual limitations on our ability to sell our products in certain foreign markets, and the risks and costs of non-compliance;

•

heightened risks of unfair or corrupt business practices in certain geographies and of improper or fraudulent sales arrangements that may impact financial results and result in restatements of financial statements and irregularities in financial statements;

•

the potential for political unrest, terrorism, hostilities or war;

•

management communication and integration problems resulting from cultural differences and geographic dispersion; and

•

multiple and possibly overlapping tax structures.

Product and service sales may be subject to foreign governmental regulations, which vary substantially from country to country. Further, we may be unable to keep up-to-date with changes in government requirements as they change from time to time. Failure to comply with these regulations could result in adverse affects to our business. In many foreign countries it is common for others to engage in business practices that are prohibited by our internal policies and procedures or U.S. regulations applicable to us. Although we implemented policies and procedures designed to ensure compliance with these laws and policies, there can be no assurance that all of our employees, contractors, channel partners and agents will comply with these laws and policies. Violations of laws or key control policies by our employees, contractors, channel partners or agents could result in delays in revenue recognition, financial reporting misstatements, fines, penalties, or the prohibition of the importation or exportation of our products and services and could have a material adverse effect on our business and results of operations.

We are subject to governmental export and import controls that could subject us to liability or impair our ability to compete in international markets.

Certain of our products are subject to U.S. export controls and may be exported outside the U.S. only with the required export license or through an export license exception, because we incorporate encryption technology into our products. If we were to fail to comply with U.S. export licensing, U.S. Customs regulations, U.S. economic sanctions and other laws we could be subject to substantial civil and criminal penalties, including fines for the company and incarceration for responsible employees and managers, and the possible loss of export or import privileges. In addition, if our channel partners fail to obtain appropriate import, export or re-export licenses or permits, we may also be adversely affected, through reputational harm and penalties. Obtaining the necessary export license for a particular sale may be time-consuming, and may result in the delay or loss of sales opportunities.

Furthermore, U.S. export control laws and economic sanctions prohibit the shipment of certain products to U.S. embargoed or sanctioned countries, governments and persons. Even though we take precautions to prevent our product from being shipped to U.S. sanctions targets, our products could be shipped to those targets by our channel partners, despite such precautions. Any such shipment could have negative consequences including government investigations and penalties and in reputational harm. In addition, various countries regulate the import of certain encryption technology, including import permitting/licensing requirements, and have enacted laws that could limit our ability to distribute our products or could limit our customers’ ability to implement our products in those countries. Changes in our products or changes in export and import regulations may create delays in the introduction of our products in international markets, prevent our customers with international operations from deploying our products globally or, in some cases, prevent the export or import of our products to certain countries, governments or persons altogether. Any change in export or import regulations, economic sanctions or related legislation, shift in the enforcement or scope of existing regulations, or change in the countries, governments, persons or technologies targeted by such regulations, could result in decreased use of our products by, or in our decreased ability to export or sell our products to, existing or potential customers with international operations. Any decreased use of our products or limitation on our ability to export or sell our products would likely adversely affect our business, financial condition and results of operations.

If we fail to comply with environmental requirements, our business, financial condition, operating results and reputation could be adversely affected.

We are subject to various environmental laws and regulations including laws governing the hazardous material content of our products and laws relating to the recycling of electrical and electronic equipment. The laws and regulations to which we are subject include the European Union, or EU, RoHS and the EU Waste Electrical and Electronic Equipment (WEEE) Directive as well as the implementing legislation of the EU member states. Similar laws and regulations have been passed or are pending in China, South Korea, Norway and Japan and may be enacted in other regions, including in the United States and we are, or may in the future be, subject to these laws and regulations.

The EU RoHS and the similar laws of other jurisdictions ban the use of certain hazardous materials such as lead, mercury and cadmium in the manufacture of electrical equipment, including our products. We have incurred costs to comply with these laws, including research and development costs, costs associated with assuring the supply of compliant components and costs associated with writing off noncompliant inventory. We expect to incur more of these costs in the future. With respect to the EU RoHS, we and our competitors rely on an exemption for lead in network infrastructure equipment. It is possible this exemption will be revoked in the near future. If revoked, if there are other changes to these laws (or their interpretation) or if new similar laws are passed in other jurisdictions, we may be required to reengineer our products to use components compatible with these regulations. This reengineering and component substitution could result in additional costs to us or disrupt our operations or logistics.

The EU has also adopted the WEEE Directive, which requires electronic goods producers to be responsible for the collection, recycling and treatment of such products. Although currently our EU International channel partners are responsible for the requirements of this directive as the importer of record in most of the European countries in which we sell our products, changes in interpretation of the regulations may cause us to incur costs or have additional regulatory requirements in the future to meet in order to comply with this directive, or with any similar laws adopted in other jurisdictions.

Our failure to comply with these and future environmental rules and regulations could result in reduced sales of our products, increased costs, substantial product inventory write-offs, reputational damage, penalties and other sanctions.

A portion of our revenue is generated by sales to government entities, which are subject to a number of challenges and risks.

Sales to U.S. and foreign federal, state and local governmental agency end-customers have accounted for a portion of our revenue in past periods, and we may in the future increase sales to government entities. Sales into government entities are subject to a number of risks. Selling to government entities can be highly competitive, expensive and time consuming, often requiring significant upfront time and expense without any assurance that we will win a sale. Government demand and payment for our products and services may be impacted by public sector budgetary cycles and funding authorizations, with funding reductions or delays adversely affecting public sector demand for our products. Most of our sales to government entities have been made indirectly through our distribution channel. Government entities may have contractual or other legal rights to terminate contracts with our distributors and resellers for convenience or due to a default, and any such termination may adversely impact our future results of operations. For example, if the distributor receives a significant portion of its revenue from sales to such governmental entity, the financial health of the distributor could be substantially harmed, which could negatively affect our future sales to such distributor. Governments routinely investigate and audit government contractors’ administrative processes, and, any unfavorable audit could result in the government refusing to continue buying our products and services, a reduction of revenue or fines or civil or criminal liability if the audit uncovers improper or illegal activities. Any such penalties could adversely impact our results of operations in a material way. Finally, for purchases by the U.S. government, the government may require certain products to be manufactured in the United States and other high cost manufacturing locations, and we may not manufacture all products in locations that meet the requirements of the U.S. government.

False detection of viruses or security breaches or false identification of spam or spyware could adversely affect our business.

Our antivirus and our intrusion prevention services may falsely detect viruses or other threats that do not actually exist. This risk is heightened by the inclusion of a “heuristics” feature in our products, which attempts to identify viruses and other threats not based on any known signatures but based on characteristics or anomalies that may indicate that a particular item is a threat. When our end-customers enable the heuristics feature in our products, the risk of falsely identifying viruses and other threats significantly increases. These false positives, while typical in the industry, may impair the perceived reliability of our products and may therefore adversely impact market acceptance of our products. Also, our antispam and antispyware services may falsely identify emails or programs as unwanted spam or potentially unwanted programs, or alternatively fail to properly identify unwanted emails or programs, particularly as spam emails or spyware are often designed to circumvent antispam or spyware products. Parties whose emails or programs are blocked by our products may seek redress against us for labeling them as spammers or spyware, or for interfering with their business. In addition, false identification of emails or programs as unwanted spam or potentially unwanted programs may reduce the adoption of our products. If our system restricts important files or applications based on falsely identifying them as malware or some other item that should be restricted, this could adversely affect end-customers’ systems and cause material system failures. Any such false identification of important files or applications could result in negative publicity, loss of end-customers and sales, increased costs to remedy any problem, and costly litigation.

If our internal network system is compromised by computer hackers, public perception of our products and services will be harmed.

We will not succeed unless the marketplace is confident that we provide effective network security protection. Because we provide network security products, we may be a more attractive target for attacks by computer hackers. Although we have not experienced significant damages from unauthorized access by a third-party of our internal network, if an actual or perceived breach of network security occurs in our internal systems it could adversely affect the market perception of our products and services. In addition, such a security breach could impair our ability to operate our business, including our ability to provide subscription and support services to our end-customers. If this happens, our revenue could decline and our business could suffer.

Our ability to sell our products is dependent on the quality of our technical support services, and our failure to offer high quality technical support services would have a material adverse effect on our sales and results of operations.

Once our products are deployed within our end-customers’ networks, our end-customers depend on our technical support services, as well as the support of our channel partners, to resolve any issues relating to our products. If we or our channel partners do not effectively assist our customers in deploying our products, succeed in helping our customers quickly resolve post-deployment issues, and provide effective ongoing support, our ability to sell additional products and services to existing customers would be adversely affected and our reputation with potential customers could be damaged. Many enterprise, service provider and government entity end-customers require higher levels of support than smaller end-customers. If we fail to meet the requirements of the larger end-customers, it may be more difficult to execute on our strategy to increase our penetration with larger end-customers.

As a result, our failure to maintain high quality support services would have a material adverse effect on our business, financial condition and results of operations.

Changes in our provision for income taxes or adverse outcomes resulting from examination of our income tax returns could adversely affect our results.

Our provision for income taxes is subject to volatility and could be adversely affected by:

•

our earnings being lower than anticipated in countries that have lower tax rates and higher than anticipated in countries that have higher tax rates;

•

changes in the valuation of our deferred tax assets and liabilities;

•

expiration of or lapses in the research and development tax credit laws;

•

transfer pricing adjustments including the effect of acquisitions on our intercompany research and development and legal structure;

•

tax effects of nondeductible compensation;

•

tax costs related to intercompany realignments;

•

changes in accounting principles; or

•

changes in tax laws and regulations including possible changes in the United States to the taxation of earnings of our foreign subsidiaries, and the deductibility of expenses attributable to foreign income, or the foreign tax credit rules.

Significant judgment is required to determine the recognition and measurement attribute prescribed in Accounting Standards Codification (ASC) 740-10 (formerly referred to as Financial Accounting Standards Board (FASB) Interpretation No. 48, Accounting for Uncertainty in Income Taxes—an interpretation of FASB No. 109 (FIN 48)). In addition, ASC 740-10 applies to all income tax positions, including the potential recovery of previously paid taxes, which if settled unfavorably could adversely impact our provision for income taxes or additional paid-in capital. Further, as a result of certain of our ongoing employment and capital investment actions and commitments, our income in certain countries is subject to reduced tax rates and in some cases is wholly exempt from tax. Our failure to meet these commitments could adversely impact our provision for income taxes. In addition, we are subject to the continuous examination of our income tax returns by the Internal Revenue Service and other tax authorities. We regularly assess the likelihood of adverse outcomes resulting from these examinations to determine the adequacy of our provision for income taxes. There can be no assurance that the outcomes from these continuous examinations will not have an adverse effect on our results of operations.

Although we released our entire valuation allowance in the year ended December 31, 2009, we may in the future be required to establish a new valuation allowance. We will continue to assess the need for a valuation allowance on the deferred tax asset by evaluating both positive and negative evidence that may exist.

Forecasting our estimated annual effective tax rate is complex and subject to uncertainty, and there may be material differences between our forecasted and actual tax rates.

Forecasts of our income tax position and effective tax rate are complex and subject to uncertainty because our income tax position for each year combines the effects of a mix of profits earned and losses incurred by us in various tax jurisdictions with a broad range of income tax rates, as well as changes in the valuation of deferred tax assets and liabilities, the impact of various accounting rules and changes to these rules and tax laws, the results of examinations by various tax authorities, and the impact of any acquisition, business combination or other reorganization or financing transaction. To forecast our global tax rate, we estimate our pre-tax profits and losses by jurisdiction and forecast our tax expense by jurisdiction. If the mix of profits and losses, our ability to use tax credits, or effective tax rates by jurisdiction is different than those estimated, our actual tax rate could be materially different than forecasted, which could have a material impact on our results of business, financial condition and results of operations.

As a multinational corporation, we conduct our business in many countries and are subject to taxation in many jurisdictions. The taxation of our business is subject to the application of multiple and sometimes conflicting tax laws and regulations as well as multinational tax conventions. Our effective tax rate is highly dependent upon the geographic distribution of our worldwide earnings or losses, the tax regulations and tax holidays in each geographic region, the availability of tax credits and carryforwards, and the effectiveness of our tax planning strategies. The application of tax laws and regulations is subject to legal and factual interpretation, judgment and uncertainty. Tax laws themselves are subject to change as a result of changes in fiscal policy, changes in legislation, and the evolution of regulations and court rulings. Consequently, taxing authorities may impose tax assessments or judgments against us that could materially impact our tax liability and/or our effective income tax rate.

In addition, we may be subject to examination of our income tax returns by the Internal Revenue Service and other tax authorities. If tax authorities challenge the relative mix of U.S. and international income, our future effective income tax rates could be adversely affected. While we regularly assess the likelihood of adverse outcomes from such examinations and the adequacy of our provision for income taxes, there can be no assurance that such provision is sufficient and that a determination by a tax authority will not have an adverse effect on our business, financial condition and results of operations.

Our inability to acquire and integrate other businesses, products or technologies could seriously harm our competitive position.

In order to remain competitive, we may seek to acquire additional businesses, products, or technologies and intellectual property, such as patents. If we identify an appropriate acquisition candidate, we may not be successful in negotiating the terms of the acquisition, financing the acquisition, or effectively integrating the acquired business, product, technology or intellectual property into our existing business and operations. We may have difficulty incorporating acquired technologies, intellectual property or products with our existing product lines and maintaining uniform standards, controls, procedures and policies. Our due diligence may fail to identify all of the problems, liabilities or other shortcomings or challenges of an acquired business, product or technology, including issues with intellectual property, product quality or product architecture, regulatory compliance practices, revenue recognition or other accounting practices or employee or customer issues. In addition, any acquisitions we are able to complete may not be accretive to earnings and may not result in any synergies or other benefits we had expected to achieve, which could result in write-offs that could be substantial. Further, completing a potential acquisition and integrating acquired businesses, products, technologies or intellectual property will significantly divert management time and resources.

Our business is subject to the risks of warranty claims, product returns, product liability and product defects.

Our products are very complex and, despite testing prior to their release, have contained and may contain undetected defects or errors, especially when first introduced or when new versions are released. For example, one of our high-end product models has been experiencing a defect in limited deployments. Product errors have affected the performance of our products and could delay the development or release of new products or new versions of products, adversely affect our reputation and our end-customers’ willingness to buy products from us, and adversely affect market acceptance or perception of our products. Any such errors or delays in releasing new products or new versions of products or allegations of unsatisfactory performance could cause us to lose revenue or market share, increase our service costs, cause us to incur substantial costs in redesigning the products, cause us to lose significant end-customers, subject us to liability for damages and divert our resources from other tasks, any one of which could materially and adversely affect our business, results of operations and financial condition. Our products must successfully interoperate with products from other vendors. As a result, when problems occur in a network, it may be difficult to identify the sources of these problems. The occurrence of hardware and software errors, whether or not caused by our products, could delay or reduce market acceptance of our products, and have an adverse effect on our business and financial performance, and any necessary revisions may cause us to incur significant expenses. The occurrence of any such problems could harm our business, financial condition and results of operations.

Although we have limitation of liability provisions in our standard terms and conditions of sale, they may not fully or effectively protect us from claims as a result of federal, state or local laws or ordinances or unfavorable judicial decisions in the United States or other countries. The sale and support of our products also entail the risk of product liability claims. We maintain insurance to protect against certain claims associated with the use of our products, but our insurance coverage may not adequately cover any claim asserted against us. In addition, even claims that ultimately are unsuccessful could result in our expenditure of funds in litigation and divert management’s time and other resources.

Our business is subject to the risks of earthquakes, fire, power outages, floods and other catastrophic events, and to interruption by manmade problems such as terrorism.

A significant natural disaster, such as an earthquake, fire or a flood, or a significant power outage could have a material adverse impact on our business, operating results and financial condition. Our corporate headquarters are located in the San Francisco Bay Area, a region known for seismic activity. In addition, natural disasters could affect our manufacturing vendors or logistics providers’ ability to perform services such as manufacturing products on a timely basis and assisting with shipments on a timely basis. For example, our primary international logistics provider is located in Taiwan which is an area known for typhoons. In the event our or our service providers’ information technology systems or manufacturing or logistics abilities are hindered by any of the events discussed above, shipments could be delayed, resulting in missing financial targets, such as revenue and shipment targets, for a particular quarter. In addition, acts of terrorism could cause disruptions in our business or the business of our manufacturers, logistics providers, partners, or end-customers or the economy as a whole. Given our typical concentration of sales at each quarter end, any disruption in the business of our manufacturers, logistics providers, partners or end-customers that impacts sales at the end of our quarter could have a significant adverse impact on our quarterly results. All of the aforementioned risks may be augmented if the disaster recovery plans for us and our suppliers prove to be inadequate. To the extent that any of the above results in delays or cancellations of customer orders, or the delay in the manufacture, deployment or shipment of our products, our business, financial condition and results of operations would be adversely affected.

Risks Related to Our Industry

The network security market is rapidly evolving and the complex technology incorporated in our products makes them difficult to develop. If we do not accurately predict, prepare for and respond promptly to technological and market developments and changing end-customer needs, our competitive position and prospects will be harmed.

The network security market is expected to continue to evolve rapidly. Moreover, many of our end-customers operate in markets characterized by rapidly changing technologies and business plans, which require them to add numerous network access points and adapt increasingly complex enterprise networks, incorporating a variety of hardware, software applications, operating systems and networking protocols. In addition, computer hackers and others who try to attack networks employ increasingly sophisticated techniques to gain access to and attack systems and networks. The technology in our products is especially complex because it needs to effectively identify and respond to new and increasingly sophisticated methods of attack, while minimizing the impact on network performance. Additionally, some of our new products and enhancements may require us to develop new hardware architectures and ASICs that involve complex, expensive and time consuming research and development processes. Although the market expects rapid introduction of new products or product enhancements to respond to new threats, the development of these products is difficult and the timetable for commercial release and availability is uncertain and there can be long time periods between releases and availability of new products. We have in the past and may in the future experience unanticipated delays in the availability of new products and services and fail to meet previously announced timetables for such availability. For example, in the first quarter of fiscal 2009, we released a new model within our FortiGate product line and, after its initial release, we detected errors in the product that required us to redesign certain aspects of the product which delayed the availability of the product for one quarter and delayed our recognition of revenue from large orders that included such product until the following quarter when the product became available. If we do not quickly respond to the rapidly changing and rigorous needs of our end-customers by developing and releasing and making available on a timely basis new products and services or enhancements that can respond adequately to new security threats, our competitive position and business prospects will be harmed.

Our URL database for our Web filtering service may fail to keep pace with the rapid growth of URLs and may not categorize websites in accordance with our end-customers’ expectations.

The success of our Web filtering service depends on the breadth and accuracy of our URL database. Although our URL database currently catalogs millions of unique URLs, it contains only a portion of the URLs for all of the websites that are available on the Internet. In addition, the total number of URLs and software applications is growing rapidly, and we expect this rapid growth to continue in the future. Accordingly, we must identify and categorize content for our security risk categories at an extremely rapid rate. Our database and technologies may not be able to keep pace with the growth in the number of websites, especially the growing amount of content utilizing foreign languages and the increasing sophistication of malicious code and the delivery mechanisms associated with spyware, phishing and other hazards associated with the Internet. Further, the ongoing evolution of the Internet and computing environments will require us to continually improve the functionality, features and reliability of our Web filtering function. Any failure of our databases to keep pace with the rapid growth and technological change of the Internet will impair the market acceptance of our products, which in turn will harm our business, financial condition and results of operations.

In addition, our Web filtering service may not be successful in accurately categorizing Internet and application content to meet our end-customers’ expectations. We rely upon a combination of automated filtering technology and human review to categorize websites and software applications in our proprietary databases. Our end-customers may not agree with our determinations that particular URLs should be included or not included in specific categories of our databases. In addition, it is possible that our filtering processes may place material that is objectionable or that presents a security risk in categories that are generally unrestricted by our users’ Internet and computer access policies, which could result in such material not being blocked from the network. Conversely, we may miscategorize websites such that access is denied to websites containing information that is important or valuable to our customers. Any miscategorization could result in customer dissatisfaction and harm our reputation. Any failure to effectively categorize and filter websites according to our end-customers’ and channel partners’ expectations will impair the growth of our business.

If our new products and product enhancements do not achieve sufficient market acceptance, our results of operations and competitive position will suffer.

We spend substantial amounts of time and money to research and develop new products and enhanced versions of our existing products to incorporate additional features, improved functionality or other enhancements in order to meet our customers’ rapidly evolving demands for network security in our highly competitive industry. When we develop a new product or an enhanced version of an existing product, we typically incur expenses and expend resources upfront to market, promote and sell the new offering. Therefore, when we develop and introduce new or enhanced products, they must achieve high levels of market acceptance in order to justify the amount of our investment in developing and bringing them to market.

Our new products or product enhancements could fail to attain sufficient market acceptance for many reasons, including:

•

delays in releasing our new products or enhancements to the market;

•

failure to accurately predict market demand in terms of product functionality and to supply products that meet this demand in a timely fashion;

•

inability to interoperate effectively with the networks or applications of our prospective end-customers;

•

inability to protect against new types of attacks or techniques used by hackers;

•

defects, errors or failures;

•

negative publicity about their performance or effectiveness;

•

introduction or anticipated introduction of competing products by our competitors;

•

poor business conditions for our end-customers, causing them to delay IT purchases;

•

easing of regulatory requirements around security; and

•

reluctance of customers to purchase products incorporating open source software.

If our new products or enhancements do not achieve adequate acceptance in the market, our competitive position will be impaired, our revenue will be diminished and the effect on our operating results may be particularly acute because of the significant research, development, marketing, sales and other expenses we incurred in connection with the new product or enhancement.

Unless we develop better market awareness of our company and our products, our revenue may not continue to grow.

We are a relatively new entrant in the network security market and we believe that we have not yet established sufficient market awareness of our participation in that market. Market awareness of our capabilities and products is essential to our continued growth and our success in all of our markets, particularly for the large enterprise, service provider and government entities markets. If our marketing programs are not successful in creating market awareness of our company and products, our business, financial condition and results of operations will be adversely affected, and we will not be able to achieve sustained growth.

Demand for Unified Threat Management products may be limited by market perception that UTM products are inferior to network security solutions from multiple vendors.

Sales of most of our products depend on increased demand for UTM products. If the UTM market fails to grow as we anticipate, our business will be seriously harmed. Target customers may view UTM “all-in-one” solutions as inferior to security solutions from multiple vendors because of, among other things, their perception that UTM products provide security functions from only a single vendor and do not allow users to choose “best-of-breed” defenses from among the wide range of dedicated security applications available. Target customers might also perceive that, by combining multiple security functions into a single platform, UTM solutions create a “single point of failure” in their networks, which means that an error, vulnerability or failure of the UTM product may place the entire network at risk. In addition, the market perception that UTM solutions may be suitable only for small and medium sized businesses because UTM lacks the performance capabilities and functionality of other solutions may harm our sales to large enterprise, service provider, and government entity end-customers. If the foregoing concerns and perceptions become prevalent, even if there is no factual basis for these concerns and perceptions, or if other issues arise with the UTM market in general, demand for UTM products could be severely limited, which would limit our growth and harm our business, financial condition and results of operations. Further a successful and publicized targeted attack against us or another well known UTM vendor exposing a “single point of failure” could significantly increase these concerns and perceptions and may harm our business and results of operations.

We face intense competition in our market, especially from larger, better-known companies, and we may lack sufficient financial or other resources to maintain or improve our competitive position.

The market for network security products is intensely competitive and we expect competition to intensify in the future. Our competitors include networking companies such as Cisco Systems, Inc. and Juniper Networks, Inc., security vendors such as Check Point Software Technologies Ltd., McAfee, Inc., and SonicWALL, Inc., and other point solution security vendors.

Many of our existing and potential competitors enjoy substantial competitive advantages such as:

•

greater name recognition and longer operating histories;

•

larger sales and marketing budgets and resources;

•

broader distribution and established relationships with distribution partners and end-customers;

•

access to larger customer bases;

•

greater customer support resources;

•

greater resources to make acquisitions;

•

lower labor and development costs; and

•

substantially greater financial, technical and other resources.

In addition, some of our larger competitors have substantially broader product offerings and leverage their relationships based on other products or incorporate functionality into existing products in a manner that discourages users from purchasing our products. These larger competitors often have broader product lines and market focus, are in a better position to withstand any significant reduction in capital spending by end-customers in these markets, and will therefore not be as susceptible to downturns in a particular market. Also, many of our smaller competitors that specialize in providing protection from a single type of network security threat are often able to deliver these specialized network security products to the market more quickly than we can. Some of our smaller competitors are using third-party chips designed to accelerate performance. Conditions in our markets could change rapidly and significantly as a result of technological advancements or continuing market consolidation. Our current and potential competitors may also establish cooperative relationships among themselves or with third parties that may further enhance their resources. In addition, current or potential competitors may be acquired by third parties with greater available resources, such as Juniper’s acquisition of NetScreen Technologies, Inc., McAfee’s acquisition of Secure Computing Corporation and Check Point’s acquisition of Nokia’s security appliance business. As a result of such acquisitions, our current or potential competitors might be able to adapt more quickly to new technologies and customer needs, devote greater resources to the promotion or sale of their products and services, initiate or withstand substantial price competition, take advantage of acquisition or other opportunities more readily or develop and expand their product and service offerings more quickly than we do. In addition, our competitors may bundle products and services competitive with ours with other products and services. Customers may accept these bundled products and services rather than separately purchasing our products and services. Due to budget constraints or economic downturns, organizations may be more willing to incrementally add solutions to their existing network security infrastructure from competitors than to replace it with our solutions. These competitive pressures in our market or our failure to compete effectively may result in price reductions, fewer customer orders, reduced revenue and gross margins and loss of market share.

If functionality similar to that offered by our products is incorporated into existing network infrastructure products, organizations may decide against adding our appliances to their network, which would have an adverse effect on our business.

Large, well-established providers of networking equipment such as Cisco Systems, Inc. and Juniper Networks, Inc. offer, and may continue to introduce, network security features that compete with our products, either in stand-alone security products or as additional features in their network infrastructure products. The inclusion of, or the announcement of an intent to include, functionality perceived to be similar to that offered by our security solutions in networking products that are already generally accepted as necessary components of network architecture may have an adverse effect on our ability to market and sell our products. Furthermore, even if the functionality offered by network infrastructure providers is more limited than our products, a significant number of customers may elect to accept such limited functionality in lieu of adding appliances from an additional vendor such as us. Many organizations have invested substantial personnel and financial resources to design and operate their networks and have established deep relationships with other providers of networking products, which may make them reluctant to add new components to their networks, particularly from other vendors such as us. In addition, an organization’s existing vendors or new vendors with a broad product offering may be able to offer concessions that we are not able to match because we currently offer only network security products and have fewer resources than many of our competitors. If organizations are reluctant to add additional network infrastructure from new vendors or otherwise decide to work with their existing vendors, our business, financial condition and results of operations will be adversely affected.

Risks Related to Intellectual Property

Our proprietary rights may be difficult to enforce, which could enable others to copy or use aspects of our products without compensating us.

We rely primarily on patent, trademark, copyright and trade secrets laws, confidentiality procedures and contractual provisions to protect our technology. We purchased most of our issued U.S. patents and many of our pending U.S. patent applications from other entities. Valid patents may not issue from our pending applications, and the claims eventually allowed on any patents may not be sufficiently broad to protect our technology or products. Any issued patents may be challenged, invalidated or circumvented, and any rights granted under these patents may not actually provide adequate defensive protection or competitive advantages to us. Patent applications in the United States are typically not published until 18 months after filing, or, in some cases, not at all, and publications of discoveries in industry-related literature lag behind actual discoveries. We cannot be certain that we were the first to make the inventions claimed in our pending patent applications or that we were the first to file for patent protection. Additionally, the process of obtaining patent protection is expensive and time-consuming, and we may not be able to prosecute all necessary or desirable patent applications at a reasonable cost or in a timely manner. In addition, recent changes to the patent laws in the United States may bring into question the validity of certain software patents. As a result, we may not be able to obtain adequate patent protection or effectively enforce our issued patents.

Despite our efforts to protect our proprietary rights, unauthorized parties may attempt to copy aspects of our products or obtain and use information that we regard as proprietary. We generally enter into confidentiality or license agreements with our employees, consultants, vendors and customers, and generally limit access to and distribution of our proprietary information. However, we cannot assure you that the steps taken by us will prevent misappropriation of our technology. Policing unauthorized use of our technology or products is difficult. In addition, the laws of some foreign countries do not protect our proprietary rights to as great an extent as the laws of the United States, and many foreign countries do not enforce these laws as diligently as government agencies and private parties in the United States. From time-to-time, legal action by us may be necessary to enforce our patents and other intellectual property rights, to protect our trade secrets, to determine the validity and scope of the proprietary rights of others or to defend against claims of infringement or invalidity. Such litigation could result in substantial costs and diversion of resources and could negatively affect our business, operating results and financial condition. If we are unable to protect our proprietary rights (including aspects of our software and products protected other than by patent rights), we may find ourselves at a competitive disadvantage to others who need not incur the additional expense, time and effort required to create the innovative products that have enabled us to be successful to date.

Our products contain third-party open source software components, and failure to comply with the terms of the underlying open source software licenses could restrict our ability to sell our products.

Our products contain software modules licensed to us by third-party authors under “open source” licenses, including the GNU Public License (GPL), the GNU Lesser Public License (LGPL), the BSD License, the Apache License and others. From time-to-time, there have been claims against companies that distribute or use open source software in their products and services, asserting that open source software infringes the claimants’ intellectual property rights. We could be subject to suits by parties claiming infringement of intellectual property rights in what we believe to be licensed open source software. Use and distribution of open source software may entail greater risks than use of third-party commercial software, as open source licensors generally do not provide warranties or other contractual protections regarding infringement claims or the quality of the code. Some open source licenses contain requirements that we make available source code for modifications or derivative works we create based upon the type of open source software we use. If we combine our proprietary software with open source software in a certain manner, we could, under certain open source licenses, be required to release the source code of our proprietary software to the public. This would allow our competitors to create similar products with lower development effort and time and ultimately could result in a loss of product sales for us.

Although we monitor our use of open source software to avoid subjecting our products to conditions we do not intend, the terms of many open source licenses have not been interpreted by United States courts, and there is a risk that these licenses could be construed in a way that could impose unanticipated conditions or restrictions on our ability to commercialize our products. In this event, we could be required to seek licenses from third parties to continue offering our products, to make generally available, in source code form, our proprietary code, to re-engineer our products, or to discontinue the sale of our products if re-engineering could not be accomplished on a timely basis, any of which could adversely affect our business, operating results and financial condition.

Claims by others that we infringe their proprietary technology could harm our business.

Patent and other intellectual property disputes are common in the network security industry. Third parties have asserted and may in the future assert claims of infringement of intellectual property rights against us. They may also assert such claims against our end-customers or channel partners whom we typically indemnify against claims that our products infringe the intellectual property rights of third parties. As the number of products and competitors in our market increases and overlaps occur, infringement claims may increase. Any claim of infringement by a third-party, even those without merit, could cause us to incur substantial costs defending against the claim and could distract our management from our business. In addition, future litigation may involve patent holding companies or other adverse patent owners who have no relevant product revenue and against whom our own patents may therefore provide little or no deterrence or protection.

Although third parties may offer a license to their technology, the terms of any offered license may not be acceptable and the failure to obtain a license or the costs associated with any license could cause our business, financial condition and results of operations to be materially and adversely affected. In addition, some licenses may be non-exclusive, and therefore our competitors may have access to the same technology licensed to us.

Alternatively, we may be required to develop non-infringing technology, which could require significant time, effort and expense and may ultimately not be successful. Furthermore, a successful claimant could secure a judgment or we may agree to a settlement that prevents us from distributing certain products or performing certain services or that requires us to pay substantial damages (including treble damages if we are found to have willfully infringed such claimant’s patents or copyrights), royalties or other fees. Any of these events could seriously harm our business, financial condition and results of operations.

We have been involved in patent disputes in the past, are currently involved in several patent disputes, and likely will be involved in additional disputes in the future. In May 2004, Trend Micro Incorporated filed a complaint against us alleging that we infringed a Trend Micro patent related to antivirus software. The International Trade Commission, or ITC, subsequently instituted an investigation which resulted in an exclusion order and a cease and desist order prohibiting us from selling a broad array of our products in the United States. In January 2006, we settled the lawsuit with Trend Micro, and subsequently the ITC terminated its action and rescinded the orders. Pursuant to the settlement and license agreement, we initially paid Trend Micro $15.0 million. The settlement and license agreement provides for additional quarterly royalty payments, not expected to exceed 1% of our total revenue each quarter, through 2015. In November 2008, we filed a complaint against Trend Micro in the United States District Court for the Northern District of California alleging, among other claims, that the patents that are the basis for the ongoing royalty payments are invalid and consequently that we have no contractual obligation to pay the royalties. Trend Micro moved to dismiss the case, and, in June 2009, the court dismissed the case without prejudice on procedural grounds, and we appealed the dismissal in July 2009. Based on the dispute, we have ceased paying royalties under the settlement and license agreement. In August 2009, Trend Micro filed a complaint against us in the Superior Court of the State of California for Santa Clara County alleging breach of contract and seeking a declaratory judgment that we are obligated to make certain royalty payments to Trend Micro. In December 2009, we withdrew our appeal of the June 2009 dismissal by the United States District Court for the Northern District of California and filed a new complaint against Trend Micro in the United States District Court for the Northern District of California alleging, among other claims, that the patents that are the basis for the ongoing royalty payments are invalid and consequently that we have no contractual obligation to pay the royalties. In February 2010, Trend Micro filed demurrers in the state Superior Court action regarding Fortinet’s affirmative defenses that Fortinet has no obligation to pay royalties because the Trend Micro patents are invalid or unenforceable. In March 2010, Trend Micro filed a motion to dismiss our new complaint that we filed in the United States District Court for the Northern District of California. On May 3, 2010, the state court denied Trend Micro’s demurrer in its entirety. On May 12, 2010, the United States District Court for the Northern District of California denied Trend Micro’s motion to dismiss without prejudice and stayed the action before that court pending the conclusion of the state court action. Because this dispute is at an early stage, it is not possible to predict the outcome. An adverse outcome in this dispute could result in accelerated royalty payments and additional damages.

In January 2009, we filed a complaint against Palo Alto Networks, Inc. in the United States District Court for the Northern District of California alleging, among other claims, patent infringement. In September 2009, Palo Alto Networks filed a counterclaim against us alleging patent infringement. In May 2009, Enhanced Security Research, LLC, or ESR, a non-practicing entity, filed a complaint in the United States District Court for the District of Delaware alleging patent infringement by us and other defendants. In August 2009, ESR filed a substantially similar complaint against us in the same court alleging infringement of the same patents. The Palo Alto Networks and ESR cases are currently at an early stage of the litigation process. In September 2009, Deep Nines, Inc. filed a complaint against us in the United States District Court for the Eastern District of Texas alleging that at least certain of our products infringe certain of their patents. If we are unsuccessful in defending against any of Palo Alto Networks’, ESR’s or Deep Nines’ claims, our operating results and financial condition and results may be materially and adversely affected. For example, we may be required to pay substantial damages and could be prevented from selling certain of our products. Several other non-practicing patent holding companies have sent us letters proposing that we license certain of their patents, and, given this and the proliferation of lawsuits in our industry and other similar industries by both non-practicing entities and operating entities, we expect that we will be sued for patent infringement in the future, regardless of the merits of any such lawsuits. The cost to defend such lawsuits and any adverse result in such lawsuits could have a material adverse effect on our results of operations and financial condition.

We rely on the availability of third-party licenses.

Many of our products include software or other intellectual property licensed from third parties. It may be necessary in the future to renew licenses relating to various aspects of these products or to seek new licenses for existing or new products. There can be no assurance that the necessary licenses would be available on acceptable terms, if at all. The inability to obtain certain licenses or other rights or to obtain such licenses or rights on favorable terms, or the need to engage in litigation regarding these matters, could result in delays in product releases until equivalent technology can be identified, licensed or developed, if at all, and integrated into our products and may have a material adverse effect on our business, operating results, and financial condition. Moreover, the inclusion in our products of software or other intellectual property licensed from third parties on a nonexclusive basis could limit our ability to differentiate our products from those of our competitors.

Risks Related to Ownership of our Common Stock

As a public company, we are subject to compliance initiatives that will require substantial time from our management and result in significantly increased costs that may adversely affect our operating results and financial condition.

The Sarbanes-Oxley Act of 2002, as well as other rules implemented by the SEC and The NASDAQ Stock Market, impose various requirements on public companies, including requiring changes in corporate governance practices. We expect these and other similar rules and regulations to substantially increase our legal and financial compliance costs. In addition there are proposed corporate governance laws and regulations under consideration that may further increase compliance costs if established as law. If compliance with these various legal and regulatory requirements diverts our management’s attention from other business concerns, it could have a material adverse effect on our business, financial condition and results of operations. The Sarbanes-Oxley Act requires, among other things, that we assess the effectiveness of our internal control over financial reporting annually and disclosure controls and procedures quarterly. In particular, for the fiscal year ending December 31, 2010, we must perform system and process evaluations and testing of our internal control over financial reporting to allow management to report on the effectiveness of our internal control over financial reporting. We are in the very early stages of the process of evaluating and documenting processes in order to comply with this requirement. We may not be able to complete our evaluation, testing and any required remediation in a timely fashion. During the evaluation and testing process, if we identify one or more material weaknesses in our internal control over financial reporting, we may be unable to assert that our internal controls are effective. We have in the past identified material weaknesses and significant deficiencies in our internal control over financial reporting, and, although we believe we have remediated the material weaknesses, certain significant deficiencies remain, and we cannot assure you that there will not be material weaknesses and additional significant deficiencies in our internal controls in the future. If we are unable to assert that our internal control over financial reporting is effective, or if our auditors are unable to express an opinion on the effectiveness of our internal controls, we could lose investor confidence in the accuracy and completeness of our financial reports, which would cause the price of our common stock to decline.

If securities or industry analysts stop publishing research or publish inaccurate or unfavorable research about our business, our stock price and trading volume could decline.

The trading market for our common stock will depend in part on the research and reports that securities or industry analysts publish about us or our business. If we do not maintain adequate research coverage or if one or more of the analysts who covers us downgrades our stock or publishes inaccurate or unfavorable research about our business, our stock price would likely decline. If one or more of these analysts ceases coverage of our company or fails to publish reports on us regularly, demand for our stock could decrease, which could cause our stock price and trading volume to decline.

The trading price of our common stock is likely to be volatile.

The market price of our common stock could be subject to wide fluctuations in response to, among other things, the risk factors described in this periodic report, and other factors beyond our control, such as fluctuations in the valuation of companies perceived by investors to be comparable to us.

Furthermore, the stock markets have experienced price and volume fluctuations that have affected and continue to affect the market prices of equity securities of many companies. These fluctuations often have been unrelated or disproportionate to the operating performance of those companies. These broad market and industry fluctuations, as well as general economic, political, and market conditions, such as recessions, interest rate changes or international currency fluctuations, may negatively affect the market price of our common stock.

In the past, many companies that have experienced volatility in the market price of their stock have been subject to securities class action litigation. We may be the target of this type of litigation in the future. Securities litigation against us could result in substantial costs and divert our management’s attention from other business concerns, which could seriously harm our business.

Future sales of shares of our common stock by stockholders could depress the price of our common stock.

Approximately 53,315,749 shares of our common stock may be sold by stockholders upon the expiration of lock-up agreements in May 2010. This is in addition to stock options that will be vested in May 2010 and eligible for exercise and sale at the expiration of the lock-up agreements. If stockholders sell, or indicate an intent to sell, substantial amounts of our common stock in the public market after the expiration of the lock-up and other legal restrictions on resale lapse, the trading price of our common stock could decline significantly.

Our failure to raise additional capital or generate the significant capital necessary to expand our operations and invest in new products could reduce our ability to compete and could harm our business.

We expect that our existing cash and cash equivalents will be sufficient to meet our anticipated cash needs for at least the next twelve months. After that, we may need to raise additional funds, and we may not be able to obtain additional debt or equity financing on favorable terms, if at all. If we raise additional equity financing, our stockholders may experience significant dilution of their ownership interests and the per-share value of our common stock could decline. Furthermore, if we engage in debt financing, the holders of debt would have priority over the holders of common stock and we may be required to accept terms that restrict our ability to incur additional indebtedness, and take other actions that would otherwise be in the interests of the stockholders and force us to maintain specified liquidity or other ratios, any of which could harm our business, operating results and financial condition. If we need additional capital and cannot raise it on acceptable terms, we may not be able to, among other things:

•

develop or enhance our products and services;

•

continue to expand our sales and marketing and research and development organizations;

•

acquire complementary technologies, products or businesses;

•

expand operations, in the United States or internationally;

•

hire, train and retain employees; or

•

respond to competitive pressures or unanticipated working capital requirements.

Our failure to do any of these things could seriously harm our business, financial condition and results of operations.

Concentration of ownership among our existing executive officers, directors and their affiliates may prevent new investors from influencing significant corporate decisions.

As of April 30, 2010, our executive officers, directors and their affiliates beneficially owned, in the aggregate, approximately 41.3% of our outstanding common stock. As a result, these stockholders are able to exercise a significant level of control over all matters requiring stockholder approval, including the election of directors, amendment of our certificate of incorporation and approval of significant corporate transactions. This control could have the effect of delaying or preventing a change of control of our company or changes in management and will make the approval of certain transactions difficult or impossible without the support of these stockholders.

Anti-takeover provisions contained in our certificate of incorporation and bylaws, as well as provisions of Delaware law, could impair a takeover attempt.

Our certificate of incorporation, bylaws and Delaware law contain provisions that could have the effect of rendering more difficult, delaying or preventing an acquisition deemed undesirable by our board of directors. Our corporate governance documents include provisions:

•

creating a classified board of directors whose members serve staggered three-year terms;

•

authorizing “blank check” preferred stock, which could be issued by the board without stockholder approval and may contain voting, liquidation, dividend and other rights superior to our common stock;

•

limiting the liability of, and providing indemnification to, our directors and officers;

•

limiting the ability of our stockholders to call and bring business before special meetings;

•

requiring advance notice of stockholder proposals for business to be conducted at meetings of our stockholders and for nominations of candidates for election to our board of directors;

•

controlling the procedures for the conduct and scheduling of board and stockholder meetings; and

•

providing the board of directors with the express power to postpone previously scheduled annual meetings and to cancel previously scheduled special meetings.

These provisions, alone or together, could delay or prevent hostile takeovers and changes in control or changes in our management.

As a Delaware corporation, we are also subject to provisions of Delaware law, including Section 203 of the Delaware General Corporation law, which prevents some stockholders holding more than 15% of our outstanding common stock from engaging in certain business combinations without approval of the holders of a substantial majority of all of our outstanding common stock.

Any provision of our certificate of incorporation or bylaws or Delaware law that has the effect of delaying or deterring a change in control could limit the opportunity for our stockholders to receive a premium for their shares of our common stock, and could also affect the price that some investors are willing to pay for our common stock.

ITEM 2.

Unregistered Sales of Equity Securities and Use of Proceeds

On November 17, 2009, our registration statement (No. 333-161190) on Form S-1 was declared effective for our initial public offering, pursuant to which we registered the offering and sale of 5,781,683 shares of common stock by us and the associated sale of 6,718,317 shares of common stock by selling stockholders, at a price of $12.50 per share. An additional sale of 1,875,000 shares of common stock by us, which constituted the underwriter’s overallotment option, occurred in the week following the initial public offering. The offering, which closed on November 24, 2009, did not terminate until after the sale of all of the shares registered on the registration statement. We sold 7,656,683 shares of our common stock for an aggregate offering price of $95,708,538 (including the underwriters’ overallotment option), and the selling stockholders sold 6,718,317 shares of common stock for an aggregate offering price of $83,978,963. The managing underwriters were Morgan Stanley & Co. Incorporated, J.P. Morgan Securities Inc. and Deutsche Bank Securities Inc.

As a result of the offering, we received net proceeds of approximately $87.4 million, which is comprised of gross proceeds from shares we issued in the initial public offering of $95.7 million plus an administrative fee reimbursement of $1.7 million, offset by underwriting discounts and commissions of $6.7 million and total offering costs of $3.3 million. No payments for such discounts, commissions and costs were made directly or indirectly to (i) any of our officers or directors or their associates, (ii) any persons owning 10% or more of any class of our equity securities, or (iii) any of our affiliates.

There was no material change in the use of proceeds from our IPO as described in our final prospectus filed with the SEC pursuant to Rule 424(b). From the effective date of the registration statement through March 31, 2010, we used all of the net proceeds for working capital purposes.
