Organization, Consolidation and Presentation of Financial Statements [Abstract]
Business and Summary of Significant Accounting Policies	Business and Summary of Significant Accounting Policies Description of the Business Zscaler, Inc. ("Zscaler," the "Company," "we," "us," or "our") is a cloud security company that developed a platform incorporating core security functionalities needed to enable fast and secure access to cloud resources based on identity, context and organization’s policies. Our solution is a purpose-built, multi-tenant, distributed cloud platform that secures user-to-app, app-to-app, and machine-to-machine communications over any network and any location. We deliver our solutions using a software-as-a-service ("SaaS") business model and sell subscriptions to customers to access our cloud platform, together with related support services. We were incorporated in Delaware in September 2007 and conduct business worldwide, with presence in North America, Europe and Asia. Our headquarters are in San Jose, California. Basis of Presentation The accompanying unaudited condensed consolidated financial statements have been prepared in conformity with accounting principles generally accepted in the United States ("U.S. GAAP") and applicable regulations of the Securities and Exchange Commission ("SEC") regarding interim financial reporting, and include the accounts of the Company and its wholly owned subsidiaries. All intercompany balances and transactions have been eliminated in consolidation. Certain information and note disclosures normally included in the financial statements prepared in accordance with U.S. GAAP have been condensed or omitted pursuant to the applicable required disclosures and regulations of the SEC. Therefore, these unaudited condensed consolidated financial statements and accompanying notes should be read in conjunction with the Company's audited consolidated financial statements and related notes in its Annual Report on Form 10-K for the fiscal year ended July 31, 2021 (the "Fiscal 2021 Form 10-K"), as filed with the SEC on September 16, 2021. Interim Unaudited Condensed Consolidated Financial Statements The accompanying condensed consolidated balance sheet as of July 31, 2021 was derived from the audited consolidated financial statements as of that date. The accompanying interim condensed consolidated financial statements, including the condensed consolidated balance sheet as of January 31, 2022, the condensed consolidated statements of operations for the three and six months ended January 31, 2022 and 2021, the condensed consolidated statements of comprehensive loss for the three and six months ended January 31, 2022 and 2021, the condensed consolidated statements of stockholders’ equity for the three and six months ended January 31, 2022 and 2021 and the condensed consolidated statements of cash flows for the six months ended January 31, 2022 and 2021 are unaudited. The related financial data and the other financial information disclosed in the accompanying notes to these condensed consolidated financial statements are also unaudited. These interim unaudited condensed consolidated financial statements have been prepared on a basis consistent with our annual consolidated financial statements and, in our opinion, include all normal recurring adjustments necessary to state fairly our quarterly results. The results of operations for the three and six months ended January 31, 2022 are not necessarily indicative of the results to be expected for our fiscal year ending July 31, 2022 or for any other future fiscal year or interim period. Use of Estimates The preparation of condensed consolidated financial statements in conformity with U.S. GAAP requires management to make estimates, judgments and assumptions that affect the amounts reported and disclosed in the financial statements and accompanying notes. Such estimates include, but are not limited to, the determination of revenue recognition, deferred revenue, deferred contract acquisition costs, valuation of acquired intangible assets, period of benefit generated from our deferred contract acquisition costs, allowance for doubtful accounts, valuation of common stock options and stock-based awards, useful lives of property and equipment, useful lives of acquired intangible assets, recoverability of goodwill, valuation of deferred tax assets and liabilities, loss contingencies related to litigation, fair value and effective interest rate of convertible senior notes, valuation of strategic investments and the discount rate used for operating leases. Management determines these estimates and assumptions based on historical experience and on various other assumptions that are believed to be reasonable. Actual results could differ significantly from these estimates, and such differences may be material to the condensed consolidated financial statements. Due to the COVID-19 pandemic, there is ongoing uncertainty and significant disruption in the global economy and financial markets. We are not aware of any specific event or circumstances that would require an update to our estimates, judgments or assumptions or a revision to the carrying value of our assets or liabilities as of the date of issuance of these condensed consolidated financial statements. These estimates, judgments and assumptions may change in the future, as new events occur or additional information is obtained . Fiscal Year Our fiscal year ends on July 31. References to fiscal 2022, for example, refer to our fiscal year ending July 31, 2022. Significant Accounting Policies Our significant accounting policies are described in the Fiscal 2021 Form 10-K. There have been no significant changes to these policies that have had a material impact on the condensed consolidated financial statements and related notes for the three and six months ended January 31, 2022. Recently Adopted Accounting Pronouncements In October 2021, the Financial Accounting Standards Board ("FASB") issued ASU No. 2021-08, Business Combinations (Topic 805) on Accounting for Contract Assets and Contract Liabilities from Contracts with Customers. This standard requires contract assets and contract liabilities from contracts with customers that are acquired in a business combination to be recognized and measured as if the acquirer had originated the original contract. Previously, acquired contract assets and liabilities were measured at fair value. This standard is effective for us in the first quarter of fiscal 2024, though early adoption is permitted. We early adopted this standard in the first quarter of fiscal 2022 and it did not have a material impact to the condensed consolidated financial statements. Recently Issued Accounting Pronouncements Not Yet Adopted In June 2020, the FASB issued ASU No. 2020-06, Debt with Conversion and Other Options (Subtopic 470-20) and Derivatives and Hedging - Contracts in Entity’s Own Equity (Subtopic 815-40). This standard eliminates the beneficial conversion and cash conversion accounting models for convertible instruments. It also amends the accounting for certain contracts in an entity’s own equity that are currently accounted for as derivatives because of specific settlement provisions. In addition, the new guidance modifies how particular convertible instruments and certain contracts that may be settled in cash or shares impact the diluted earnings per share computation. This standard is effective for us in the first quarter of fiscal 2023, using the fully retrospective or modified retrospective method, though early adoption is permitted. We are currently evaluating the potential impact of this standard on the condensed consolidated financial statements.

Contract Balances Contract liabilities consist of deferred revenue and include payments received in advance of performance under the contract. Such amounts are recognized as revenue over the contractual period. Deferred revenue, including current and noncurrent balances as of January 31, 2022 and July 31, 2021 was $759.9 million and $630.6 million, respectively. In the six months ended January 31, 2022 and 2021, we recognized revenue of $378.6 million and $228.9 million, respectively, that was included in the corresponding contract liability balance at the beginning of these periods.

We evaluate, among others, whether we have the intention to sell any of these investments and whether it is not more likely than not that we will be required to sell any of them before recovery of the amortized cost basis. Neither of these criteria were met in any period presented. We additionally evaluate whether the decline in fair value of the corporate debt securities below the amortized cost basis is related to credit losses or other factors. Based on this evaluation, we determined that unrealized losses of the above securities were primarily attributable to changes in interest rates and non-credit related factors. Accordingly, we determined that an allowance for credit losses was unnecessary for our short-term investments as of January 31, 2022 and July 31, 2021. We recorded $2.4 million and $3.9 million of accrued interest receivable within prepaid expenses and other current assets in the condensed consolidated balance sheets as of January 31, 2022 and July 31, 2021, respectively. Strategic Investments The carrying amount of our strategic investments, which consist of non-marketable investments, was $5.1 million as of January 31, 2022 and July 31, 2021, which are included within other noncurrent assets in the condensed consolidated balance sheets.

Fair Value Measurements

Fair Value Disclosures [Abstract]
Fair Value Measurements	Fair Value Measurements We measure our financial assets and liabilities at fair value at each reporting period using a fair value hierarchy which requires us to maximize the use of observable inputs and minimize the use of unobservable inputs when measuring fair value. A financial instrument’s classification within the fair value hierarchy is based upon the lowest level of input that is significant to the fair value measurement. Our money market funds are classified within Level I due to the highly liquid nature of these assets and have quoted prices in active markets. Certain of our investments in available-for-sale securities (i.e., U.S. treasury securities, U.S. government agency securities and corporate debt securities), as well as our assets and liabilities arising from our foreign currency forward contracts, are classified within Level II. The fair value of our Level II financial assets and liabilities is determined by using inputs based on non-binding market consensus prices that are primarily corroborated by observable market data or quoted market prices for similar instruments, for substantially the full term of the financial assets and liabilities. Assets and liabilities that are measured at fair value on a recurring basis consisted of the following as of January 31, 2022: Level I Level II Level III Fair Value Quoted Prices in Active Markets for Identical Assets Significant Other Observable Inputs Significant Unobservable Inputs Cash equivalents: (in thousands) Money market funds $ 279,698 $ 279,698 $ — $ — U.S. treasury securities 22,495 — 22,495 — Corporate debt securities 5,000 — 5,000 — Total $ 307,193 $ 279,698 $ 27,495 $ — Short-term investments: U.S. treasury securities $ 397,251 $ — $ 397,251 $ — U.S. government agency securities 432,628 — 432,628 — Corporate debt securities 381,511 — 381,511 — Total $ 1,211,390 $ — $ 1,211,390 $ — Total cash equivalents and short-term investments $ 1,518,583 $ 279,698 $ 1,238,885 $ — Designated derivative instruments: Foreign currency contracts assets-current (1) $ 729 $ — $ 729 $ — Foreign currency contract assets-noncurrent (2) $ 78 $ — $ 78 $ — Foreign currency contracts liabilities-current (3) $ 4,067 $ — $ 4,067 $ — Foreign currency contracts liabilities-noncurrent (4) $ 160 $ — $ 160 $ — Non-designated derivative instruments: Foreign currency contracts assets-current (1) $ 132 $ — $ 132 $ — Foreign currency contracts liabilities-current (3) $ 956 $ — $ 956 $ — (1) Reported as prepaid expenses and other current assets in the condensed consolidated balance sheets.

Derivative Instruments and Hedging Activities Disclosure [Abstract]
Derivative Instruments	Derivative Instruments As a global business, we are exposed to foreign currency exchange rate risk. Substantially all of our revenue is transacted in U.S. dollars; however, a portion of our cost of revenue and operating expenditures are incurred outside of the United States and are denominated in foreign currencies, making them subject to fluctuations in foreign currency exchange rates. In order to mitigate the impact of foreign currency fluctuations on our future cash flows and earnings, we enter into foreign currency forward contracts, which we designate as cash flow hedges. All cash flow hedges were considered effective during the three and six months ended January 31, 2022 and 2021. During the three months ended October 31, 2021, we began to use foreign currency forward contracts to mitigate variability in gains and losses generated from the remeasurement of certain monetary assets and liabilities denominated in foreign currencies. The outstanding non-designated derivative instruments are carried at fair value with changes recorded in other income (expense), net in the condensed consolidated statement of operations in the same period as the changes in fair value from the remeasurement of the underlying assets and liabilities. Cash flows from such derivatives are classified as operating activities. These foreign exchange contracts typically have maturities of approximately one As of January 31, 2022 and July 31, 2021, the total notional amount of our outstanding foreign currency forward contracts was $191.8 million and $118.9 million, respectively, for designated foreign currency forward contracts and $58.3 million and $28.2 million, respectively, for non-designated foreign currency forward contracts. The maximum length of time over which forecasted foreign currency denominated operating expenses are hedged is 18 months. Substantially all of the unrealized gains and losses related to our cash flow hedges are expected to be released into earnings over the next 12 months. Refer to Note 4, Fair Value Measurements, for the fair value of our derivative instruments as reported on the condensed consolidated balance sheet as of January 31, 2022 and July 31, 2021. During the three and six months ended January 31, 2022 and 2021, the unrealized gains and losses related to our cash flow hedges that were recognized in accumulated other comprehensive income (loss) ("AOCI") and the gains and losses reclassified into the condensed consolidated statement of operations were not material. During the three and six months ended January 31, 2022 and 2021, changes in the fair value of our non-designated derivative instruments recorded in other income (expense), net within the condensed consolidated statements of operations were not material. Our derivative contracts expose us to credit risk to the extent that the counterparties may be unable to meet the terms of the underlying contracts. We mitigate this credit risk by transacting with major financial institutions with high credit ratings and standards. We periodically assess the creditworthiness of our counterparties to ensure they continue to meet our credit quality requirements. We also enter into master netting arrangements, which permit net settlement of transactions with the same counterparty. The potential impact of these rights of set-off associated with our derivative instruments was not material as of January 31, 2022 and July 31, 2021. We are not required to pledge, and are not entitled to receive, cash collateral related to these derivative instruments. We do not enter into derivative contracts for trading or speculative purposes.

Business Combination and Asset Acquisition [Abstract]
Business Combinations	Business CombinationsDuring the three months ended January 31, 2022, we completed a business acquisition for a total purchase price consideration of $2.1 million, consisting of $0.4 million paid in cash at closing and the issuance of shares of our common stock with an aggregate fair value of $1.7 million at closing. Additionally, certain former employees of the acquired company who became our employees are entitled to receive additional consideration in the form of shares of our common stock subject to future employment services. These awards will be recognized as stock-based compensation expense during the post-combination period. Based on the valuation of the acquired intangible assets, the purchase price allocation resulted in the recognition of $1.6 million of developed technology and $0.8 million of goodwill. The developed technology will be amortized over its economic useful life of five years. Goodwill is not expected to be deductible for income tax purposes. The acquisition qualified as a stock transaction for tax purposes. As a result, we recognized a deferred tax liability for approximately $0.4 million, generated primarily from the difference between the tax basis and fair value of the acquired developed technology, which increased goodwill by the same amount. As we had a full valuation allowance as of January 31, 2022, we recorded an income tax benefit as a result of the reduction of the valuation allowance due to the establishment of the deferred tax liability in the condensed consolidated statement of operations for the three and six months ended January 31, 2022.

Convertible Senior Notes	Convertible Senior Notes On June 25, 2020, we issued $1,150.0 million in aggregate principal amount of 0.125% Convertible Senior Notes due 2025 (the “Notes”), including the exercise in full by the initial purchasers of the Notes of their option to purchase an additional $150.0 million principal amount of the Notes. The Notes are unsecured obligations and bear interest at a rate of 0.125% per year and interest is payable semiannually in arrears on January 1 and July 1 of each year, beginning on January 1, 2021. The Notes mature on July 1, 2025, unless earlier converted, redeemed or repurchased. The total net proceeds from the offering, after deducting initial purchase discounts and other debt issuance costs, was $1,130.5 million. Refer to Note 9, Convertible Senior Notes, in the Notes to Consolidated Financial Statements included in our Fiscal 2021 Form 10-K for further information on the Notes. During the three months ended January 31, 2022, the conditional conversion feature of the Notes was triggered as the last reported sale price of our common stock was greater than or equal to 130% of the conversion price of the Notes for at least 20 trading days during the period of 30 consecutive trading days ending on January 31, 2022. Accordingly, the Notes are currently convertible, in whole or in part, at the option of the holders from February 1, 2022 through April 29, 2022 (the last trading day of the fiscal quarter). Whether the Notes will be convertible following such periods will depend on the continued satisfaction of this condition or another conversion condition in the future. Conversion notices received through January 31, 2022 have not been material.

The fair value was determined based on the closing trading price per $1,000 of the Notes as of the last day of trading for the period. We consider the fair value of the Notes as of January 31, 2022 to be a Level II measurement as they are not actively traded. The fair value of the Notes is primarily affected by the trading price of our common stock and market interest rates. In connection with the pricing of the Notes, we entered into capped call transactions with the option counterparties (the "Capped Calls"). The Capped Calls each have an initial strike price of $150.80 per share, subject to certain adjustments, which corresponds to the initial conversion price of the Notes. The Capped Calls have an initial cap price of $246.76 per share, subject to certain adjustments. The Capped Calls are generally expected to reduce potential dilution to our common stock upon any conversion of the Notes and/or offset any cash payments we are required to make in excess of the principal

Commitments and Contingencies	Commitments and Contingencies Non-cancelable Purchase Obligations In the normal course of business, we enter into non-cancelable purchase commitments with various third parties to purchase products and services such as technology equipment, subscription-based cloud service arrangements, corporate and marketing events and consulting services. During the six months ended January 31, 2022, there have been no material changes outside the ordinary course of business to our non-cancelable purchase commitments from those disclosed in our Fiscal 2021 Form 10-K. Legal Matters Litigation and Claims We are a party to various litigation matters from time to time and subject to claims that arise in the ordinary course of business, including patent, commercial, product liability, employment, class action, whistleblower and other litigation and claims, as well as governmental and other regulatory investigations and proceedings. In addition, third parties may from time to time assert claims against us in the form of letters and other communications. There is no pending or threatened legal proceeding to which we are a party that, in our opinion, is likely to have a material adverse effect on our future financial results or operations; however, the results of litigation and claims are inherently unpredictable. Regardless of the outcome, litigation can have an adverse impact on us because of defense and settlement costs, diversion of management resources and other factors. The expense of litigation and the timing of this expense from period to period are difficult to estimate, subject to change and could adversely affect our results of operations.

Restricted Stock Units and Performance Stock Awards The activity of restricted stock units ("RSUs") and performance stock awards ("PSAs") consisted of the following: Underlying Shares Weighted-Average Grant Date Fair Value Aggregate (in thousands, except per share data) Balance as of July 31, 2021 7,763 $ 100.84 $ 1,831,376 Granted 1,698 268.10 Vested (1,595) 95.94 457,341 Canceled or forfeited (304) 110.87 Balance as of January 31, 2022 7,562 $ 139.04 $ 1,944,177 As of January 31, 2022, there were 0.1 million outstanding PSAs for which the performance metrics have not been defined as of such date. As a result, such awards are not considered granted for accounting purposes as of January 31, 2022 and accordingly, they have been excluded from the above table. Employee Stock Purchase Plan In fiscal 2018, we adopted the Fiscal Year 2018 Employee Stock Purchase Plan (the "ESPP"). During the three months ended January 31, 2022, employees purchased 0.1 million shares of our common stock under the ESPP at an average purchase price of $105.88 per share, resulting in total cash proceeds of $11.5 million. ESPP employee payroll contributions accrued as of January 31, 2022 and July 31, 2021 were $7.6 million and $5.2 million, respectively, and are included within accrued compensation in the condensed consolidated balance sheets. Payroll contributions accrued as of January 31, 2022 will be used to purchase shares at the end of the current ESPP purchase period ending on June 15, 2022. Payroll contributions ultimately used to purchase shares are reclassified to stockholders’ equity on the purchase date. The fair value of the purchase right for the ESPP was estimated on the grant date using the Black-Scholes option-pricing model with the following assumptions: Six Months Ended January 31, 2022 2021 Expected term (in years) 0.5 - 2.0 0.5 - 2.0 Expected stock price volatility 44.1% - 57.4% 61.1% - 67.4% Risk-free interest rate 0.1% - 0.7% 0.1% Dividend yield 0.0% 0.0% Deferred Merger Consideration In connection with a business acquisition completed during the three months ended January 31, 2022, certain former employees of the acquired company who became our employees are entitled to receive deferred merger consideration payable in shares of our common stock with an aggregate fair value of $2.6 million as of the closing date of the acquisition. These awards are subject to future employment services and will be recognized as stock-based compensation expense over the requisite service period within research and development expenses in the condensed consolidated statements of operations. Stock-based Compensation Expense The components of stock-based compensation expense, net of amounts capitalized in the development of software for internal-use, recognized in the condensed consolidated statements of operations consisted of the following: Three Months Ended January 31, Six Months Ended January 31, 2022 2021 2022 2021 (in thousands) Cost of revenue $ 5,481 $ 3,092 $ 10,467 $ 6,101 Sales and marketing 44,586 30,081 85,307 61,401 Research and development 28,626 16,363 55,885 30,485 General and administrative 20,295 11,844 37,232 20,578 Total $ 98,988 $ 61,380 $ 188,891 $ 118,565 During the three months ended January 31, 2022 and 2021, we capitalized stock-based compensation associated with the development of software for internal-use of $2.7 million and $1.1 million, respectively. During the six months ended January 31, 2022 and 2021, the amount capitalized was $5.2 million and $2.5 million, respectively. Capitalized stock-based compensation is amortized on a straight-line basis over the estimated useful life of the underlying capitalized software application, typically three years. Amortization expense is recorded primarily within cost of revenue in the condensed consolidated statement of operations.

Income Tax Disclosure [Abstract]
Income Taxes	Income Taxes Our tax provision for interim periods is determined using an estimate of our annual effective tax rate, adjusted for discrete items, if any, that arise during the period. Each quarter, we update our estimate of the annual effective tax rate, and if the estimated annual effective tax rate changes, we make a cumulative adjustment in such period. Our quarterly tax provision, and estimate of our annual effective tax rate, is subject to variation due to several factors, including variability in pre-tax income (or loss), the mix of jurisdictions to which such income relates, changes in how we do business, and tax law developments. Our estimated annual effective tax rate for the year differs from the U.S. statutory rate of 21% as a result of our U.S. losses for which no benefit will be realized, as well as our foreign operations which are subject to tax rates that differ from those in the United States. We recorded a provision for income taxes of $2.2 million and $1.7 million for the three months ended January 31, 2022 and 2021, respectively, and $4.6 million and $2.2 million for the six months ended January 31, 2022 and 2021, respectively. We are subject to income tax in the United States as well as other tax jurisdictions in which we conduct business. Earnings from our non-U.S. operations are subject to income taxes in the countries in which we operate. Our provision for income taxes consists primarily of both income and withholding taxes in the foreign jurisdictions in which we conduct business, offset by a tax benefit of $0.4 million for the partial release of our U.S. valuation allowance related to a business acquisition completed during the three months ended January 31, 2022. The realization of deferred tax assets is dependent upon the generation of sufficient taxable income of the appropriate character in future periods. We assess our ability to realize the deferred tax assets on a quarterly basis and we establish a valuation allowance if it is more-likely-than-not that some portion of the deferred tax assets will not be realized. We weigh all available positive and negative evidence, including our earnings history and results of recent operations, scheduled reversals of deferred tax liabilities, projected future taxable income and tax planning strategies. Due to the weight of objectively verifiable negative evidence, including our history of losses in certain jurisdictions, we believe that it is more likely than not that our U.S. federal, state, and U.K. deferred tax assets will not be realized. Accordingly, we have maintained a valuation allowance on our U.S. federal, state and U.K. deferred tax assets.

Net Loss Per Share	Net Loss Per Share The following table sets forth the computation of basic and diluted net loss per share: Three Months Ended Six Months Ended 2022 2021 2022 2021 (in thousands) Net loss $ (100,420) $ (67,541) $ (191,221) $ (122,547) Weighted-average shares used in computing net loss per share, basic and diluted 140,515 135,024 139,901 134,238 Net loss per share, basic and diluted $ (0.71) $ (0.50) $ (1.37) $ (0.91) Since we have reported net losses for all periods presented, we have excluded all potentially dilutive securities from the calculation of the diluted net loss per share as their effect is antidilutive and accordingly, the basic and diluted net loss per share is the same for all periods presented. The following table summarizes the potentially dilutive securities outstanding as of January 31, 2022 and 2021 that were excluded from the computation of diluted net loss per share as their effect would be antidilutive: January 31, 2022 2021 (in thousands) Unvested RSUs and shares of common stock 6,843 7,609 Stock options 1,921 3,632 Unvested PSAs (1) 835 629 Share purchase rights under the ESPP 798 493 Convertible senior notes (2) 7,626 7,626 Total 18,023 19,989 (1) The number of unvested PSAs is estimated at 100% of the target number of shares granted and excludes unvested PSAs for which performance conditions have not been established as of January 31, 2022 and 2021, as they are not considered outstanding for accounting purposes. Refer to Note 11, Stock-Based Compensation, for further information. (2) The shares underlying the conversion option in the Notes were not considered in the calculation of diluted net loss per share as the effect would have been antidilutive. Based on the initial conversion price, the entire outstanding principal amount of the Notes as of January 31, 2022 would have been convertible into approximately 7.6 million shares of our common stock, as reflected in the above table. As we expect to settle the principal amount of the Notes in cash, only the amount by which the conversion value exceeds the aggregate principal amount of the Notes (the "conversion spread") is considered in the diluted earnings per share computation under the treasury stock method. The conversion spread has a dilutive impact on diluted net income per share when the average market price of our common stock for a given reporting period exceeds the initial conversion price of $150.80 per share for the Notes. Conversion notices received through January 31, 2022 have not been material. In connectio

Organization, Consolidation and Presentation of Financial Statements [Abstract]
Basis of Presentation	Basis of Presentation The accompanying unaudited condensed consolidated financial statements have been prepared in conformity with accounting principles generally accepted in the United States ("U.S. GAAP") and applicable regulations of the Securities and Exchange Commission ("SEC") regarding interim financial reporting, and include the accounts of the Company and its wholly owned subsidiaries. All intercompany balances and transactions have been eliminated in consolidation. Certain information and note disclosures normally included in the financial statements prepared in accordance with U.S. GAAP have been condensed or omitted pursuant to the applicable required disclosures and regulations of the SEC. Therefore, these unaudited condensed consolidated financial statements and accompanying notes should be read in conjunction with the Company's audited consolidated financial statements and related notes in its Annual Report on Form 10-K for the fiscal year ended July 31, 2021 (the "Fiscal 2021 Form 10-K"), as filed with the SEC on September 16, 2021.
Use of Estimates	Use of Estimates The preparation of condensed consolidated financial statements in conformity with U.S. GAAP requires management to make estimates, judgments and assumptions that affect the amounts reported and disclosed in the financial statements and accompanying notes. Such estimates include, but are not limited to, the determination of revenue recognition, deferred revenue, deferred contract acquisition costs, valuation of acquired intangible assets, period of benefit generated from our deferred contract acquisition costs, allowance for doubtful accounts, valuation of common stock options and stock-based awards, useful lives of property and equipment, useful lives of acquired intangible assets, recoverability of goodwill, valuation of deferred tax assets and liabilities, loss contingencies related to litigation, fair value and effective interest rate of convertible senior notes, valuation of strategic investments and the discount rate used for operating leases. Management determines these estimates and assumptions based on historical experience and on various other assumptions that are believed to be reasonable. Actual results could differ significantly from these estimates, and such differences may be material to the condensed consolidated financial statements. Due to the COVID-19 pandemic, there is ongoing uncertainty and significant disruption in the global economy and financial markets. We are not aware of any specific event or circumstances that would require an update to our estimates, judgments or assumptions or a revision to the carrying value of our assets or liabilities as of the date of issuance of these condensed consolidated financial statements. These estimates, judgments and assumptions may change in the future, as new events occur or additional information is obtained .
Fiscal Year	Fiscal Year Our fiscal year ends on July 31. References to fiscal 2022, for example, refer to our fiscal year ending July 31, 2022.
Recently Adopted Accounting Pronouncements; Recently Issued Accounting Pronouncements Not Yet Adopted	Recently Adopted Accounting Pronouncements In October 2021, the Financial Accounting Standards Board ("FASB") issued ASU No. 2021-08, Business Combinations (Topic 805) on Accounting for Contract Assets and Contract Liabilities from Contracts with Customers. This standard requires contract assets and contract liabilities from contracts with customers that are acquired in a business combination to be recognized and measured as if the acquirer had originated the original contract. Previously, acquired contract assets and liabilities were measured at fair value. This standard is effective for us in the first quarter of fiscal 2024, though early adoption is permitted. We early adopted this standard in the first quarter of fiscal 2022 and it did not have a material impact to the condensed consolidated financial statements. Recently Issued Accounting Pronouncements Not Yet Adopted In June 2020, the FASB issued ASU No. 2020-06, Debt with Conversion and Other Options (Subtopic 470-20) and Derivatives and Hedging - Contracts in Entity’s Own Equity (Subtopic 815-40). This standard eliminates the beneficial conversion and cash conversion accounting models for convertible instruments. It also amends the accounting for certain contracts in an entity’s own equity that are currently accounted for as derivatives because of specific settlement provisions. In addition, the new guidance modifies how particular convertible instruments and certain contracts that may be settled in cash or shares impact the diluted earnings per share computation. This standard is effective for us in the first quarter of fiscal 2023, using the fully retrospective or modified retrospective method, though early adoption is permitted. We are currently evaluating the potential impact of this standard on the condensed consolidated financial statements.

Earnings Per Share [Abstract]
Schedule of Net Loss Per Share, Basic and Diluted	The following table sets forth the computation of basic and diluted net loss per share: Three Months Ended Six Months Ended 2022 2021 2022 2021 (in thousands) Net loss $ (100,420) $ (67,541) $ (191,221) $ (122,547) Weighted-average shares used in computing net loss per share, basic and diluted 140,515 135,024 139,901 134,238 Net loss per share, basic and diluted $ (0.71) $ (0.50) $ (1.37) $ (0.91)
Schedule of Antidilutive Securities Excluded from Computation of Earnings Per Share	The following table summarizes the potentially dilutive securities outstanding as of January 31, 2022 and 2021 that were excluded from the computation of diluted net loss per share as their effect would be antidilutive: January 31, 2022 2021 (in thousands) Unvested RSUs and shares of common stock 6,843 7,609 Stock options 1,921 3,632 Unvested PSAs (1) 835 629 Share purchase rights under the ESPP 798 493 Convertible senior notes (2) 7,626 7,626 Total 18,023 19,989 (1) The number of unvested PSAs is estimated at 100% of the target number of shares granted and excludes unvested PSAs for which performance conditions have not been established as of January 31, 2022 and 2021, as they are not considered outstanding for accounting purposes. Refer to Note 11, Stock-Based Compensation, for further information. (2) The shares underlying the conversion option in the Notes were not considered in the calculation of diluted net loss per share as the effect would have been antidilutive. Based on the initial conversion price, the entire outstanding principal amount of the Notes as of January 31, 2022 would have been convertible into approximately 7.6 million shares of our common stock, as reflected in the above table. As we expect to settle the principal amount of the Notes in cash, only the amount by which the conversion value exceeds the aggregate principal amount of the Notes (the "conversion spread") is considered in the diluted earnings per share computation under the treasury stock method. The conversion spread has a dilutive impact on diluted net income per share when the average market price of our common stock for a given reporting period exceeds the initial conversion price of $150.80 per share for the Notes. Conversion notices received through January 31, 2022 have not been material. In connectio
