Business and Summary of Significant Accounting Policies <div style="margin-bottom:12pt;text-indent:18pt">Business Description</div><div style="margin-bottom:12pt;text-indent:18pt">Tenable Holdings, Inc. (the “Company,” “we,” "us," or “our”) is a provider of Cyber Exposure solutions, which is a discipline for managing, measuring and comparing cybersecurity risk in the digital era. Our platform offerings provide broad visibility into security issues such as vulnerabilities, misconfigurations, internal and regulatory compliance violations and other indicators of the state of an organization’s security across IT infrastructure and applications, cloud environments and industrial internet of things and operational technology environments.</div><div style="margin-bottom:12pt;text-indent:18pt">Basis of Presentation</div><div style="margin-bottom:12pt;text-indent:18pt">The accompanying consolidated financial statements include the accounts of Tenable Holdings, Inc. and our wholly owned subsidiaries and have been prepared in conformity with United States generally accepted accounting principles (“GAAP”). All intercompany accounts and transactions have been eliminated in consolidation.</div><div style="margin-bottom:12pt;text-indent:18pt">Initial Public Offering</div><div style="margin-bottom:12pt;text-indent:18pt">On July 30, 2018, we completed our initial public offering ("IPO"), in which we issued and sold 12,535,000 shares of common stock at a price to the public of $23.00 per share, including 1,635,000 shares of common stock purchased by our underwriters from the full exercise of their over-allotment option. All of the shares sold in the IPO were sold by the Company. We received net proceeds of $264.6 million after deducting underwriting discounts and commissions and other offering expenses.</div><div style="margin-bottom:12pt;text-indent:18pt">Upon the completion of our IPO, all 15,847,500 shares of our Series A Redeemable Convertible Preferred Stock ("Series A") and 39,538,354 shares of our Series B Redeemable Convertible Preferred Stock ("Series B") automatically converted into an aggregate of 55,385,854 shares of our common stock. Our Amended and Restated Certificate of Incorporation adopted in connection with the IPO authorizes a total of 500,000,000 shares of common stock and 10,000,000 shares of preferred stock.</div><div style="margin-bottom:12pt;text-indent:18pt">Use of Estimates</div><div style="margin-bottom:12pt;text-indent:18pt">The preparation of consolidated financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the amounts reported in the consolidated financial statements and accompanying notes. These estimates include, but are not limited to, the determination of the estimated economic life of perpetual licenses for revenue recognition, the estimated period of benefit for deferred commissions, the useful lives of long-lived assets, the fair value of acquired intangible assets, the valuation of stock-based compensation, including the estimated underlying fair value of our common stock prior to our IPO, the incremental borrowing rate for operating leases, and the valuation of deferred tax assets. We base these estimates on historical experience and on various other assumptions that we believe to be reasonable. Actual results could differ significantly from these estimates.</div><div style="margin-bottom:12pt;text-indent:18pt">Foreign Currency</div><div style="margin-bottom:12pt;text-indent:18pt">The functional currency for all of our foreign subsidiaries is the U.S. dollar. Assets and liabilities denominated in other currencies are remeasured into U.S. dollars at current exchange rates for monetary assets and liabilities and at historical exchange rates for non-monetary assets and liabilities. We bill our customers in U.S. dollars. Expenses incurred in non U.S. dollar currencies are remeasured into U.S. dollars when incurred. Remeasurement losses in currencies other than the functional currency were $1.7 million, $1.1 million and $1.0 million in 2020, 2019 and 2018, respectively, and are included as a component of other expense, net in the consolidated statements of operations.</div><div style="margin-bottom:12pt;text-indent:18pt">Revenue Recognition</div><div style="margin-bottom:3pt;text-indent:18pt">We recognize revenue in order to depict the transfer of promised goods or services to customers in an amount that reflects the consideration we expect to be entitled in exchange for those goods or services. To achieve this, we apply the following steps:</div><div style="margin-bottom:3pt;padding-left:36pt;text-indent:-18pt">•Identify the contract with a customer</div><div style="margin-bottom:3pt;padding-left:36pt;text-indent:-18pt">•Identify the performance obligations in the contract</div><div style="margin-bottom:3pt;padding-left:36pt;text-indent:-18pt">•Determine the transaction price</div><div style="margin-bottom:3pt;padding-left:36pt;text-indent:-18pt">•Allocate the transaction price to the performance obligations in the contract</div><div style="margin-bottom:12pt;padding-left:36pt;text-indent:-18pt">•Recognize revenue when or as performance obligations are satisfied</div><div style="margin-bottom:12pt;text-indent:18pt">In situations where we enter into a contractual arrangement that includes non-standard terms and conditions, such as acceptance provisions or options to purchase additional products and services, as well as contract modifications, we apply judgment in identifying and assessing the impact on revenue recognition. </div><div style="margin-bottom:12pt;text-indent:18pt">We generate revenue from subscription arrangements for software and cloud-based solutions, perpetual licenses, maintenance associated with perpetual licenses, and professional services and other revenue. We begin to recognize revenue when control of our software or services is transferred to the customer, which for sales made through distributors is concurrent with the transfer to the end user.</div><div style="margin-bottom:12pt;text-indent:18pt">Subscription Revenue </div><div style="margin-bottom:12pt;text-indent:18pt">Subscription arrangements generally have annual or multi-year contractual terms and allow customers to use our software or cloud solutions, including ongoing software updates and the ability to identify the latest cybersecurity vulnerabilities. Revenue is recognized ratably over the subscription term given the critical utility provided by the ongoing updates that are released throughout the contract period. </div><div style="margin-bottom:12pt;text-indent:18pt">Perpetual License and Maintenance Revenue </div><div style="margin-bottom:12pt;text-indent:18pt">Our perpetual licenses are generally sold with one or more years of maintenance, which include ongoing software updates and the ongoing ability to identify the latest cybersecurity vulnerabilities. Given the critical utility provided by the ongoing software updates and updated ability to identify network vulnerabilities included in maintenance, we combine the perpetual license and the maintenance into a single performance obligation. Perpetual license arrangements generally contain a material right related to the customer’s ability to renew maintenance at a price that is less than the initial license fee. We apply a practical alternative to allocating a portion of the transaction price to the material right performance obligation and estimate a hypothetical transaction price which includes fees for expected maintenance renewals based on the estimated economic life of the perpetual license contracts. We allocate the transaction price between the cybersecurity subscription provided in the initial contract and the material right related to expected contract renewals based on the hypothetical transaction price. We recognize the amount allocated to the combined license and maintenance performance obligation over the initial contractual period, which is generally one year. We recognize the amount allocated to the material right over the expected maintenance renewal period, which begins at the end of the initial contractual term and is generally four years. We have estimated the five-year economic life of perpetual license contracts based on historical contract attrition, expected renewal periods, the lifecycle of the our technology and other factors. While we believe that the estimates we have made are reasonable and appropriate, different assumptions and estimates could materially impact our reported financial results.</div><div style="margin-bottom:12pt;text-indent:18pt">Professional Services and Other Revenue </div><div style="margin-bottom:12pt;text-indent:18pt">Professional services and other revenue is primarily comprised of advisory services and training related to the deployment and optimization of our products. These services do not result in significant customization of our products. Professional services and other revenue is recognized as the services are performed. </div><div style="margin-bottom:12pt;text-indent:18pt">Contracts with Multiple Performance Obligations </div><div style="margin-bottom:12pt;text-indent:18pt">In cases where our contracts with customers contain multiple performance obligations, the contract transaction price is allocated on a relative standalone selling price basis. We typically determine standalone selling price based on observable selling prices of our products and services. </div><div style="margin-bottom:12pt;text-indent:18pt">Variable Consideration </div><div style="margin-bottom:12pt;text-indent:18pt">We record revenue from sales at the net sales price, which is the transaction price, including estimates of variable consideration when applicable. Certain of our customers may be entitled to receive credits and in certain circumstances, refunds, if service level commitments are not met. We have not historically experienced significant incidents affecting the ability to meet these service level commitments and any estimated refunds related to these agreements have not been material. </div><div style="margin-bottom:12pt;text-indent:18pt">Sales through our channel network of distributors and resellers are generally discounted as compared to the price that we would sell to an end user. Revenue for sales through our channel network is recorded net of any distributor or reseller margin. </div><div style="margin-bottom:12pt;text-indent:18pt">Cash and Cash Equivalents</div><div style="margin-bottom:12pt;text-indent:18pt">We consider all highly liquid financial instruments with an original maturity of three months or less when purchased to be cash equivalents.</div><div style="margin-bottom:12pt;text-indent:18pt">At December 31, 2020 and 2019, cash and cash equivalents included $0.4 million of restricted cash, which is related to collateral for a lease and credit card deposits. At December 31, 2020 and 2019, cash and cash equivalents excluded $0.2 million and $0.3 million, respectively, of restricted cash, which is related to an account established as collateral for a lease arrangement and is included in other assets on the consolidated balance sheets.</div><div style="margin-bottom:12pt;text-indent:18pt">Fair Value of Financial Instruments</div><div style="margin-bottom:12pt;text-indent:18pt">Fair value is defined as the price that would be received from selling an asset, or paid to transfer a liability, in an orderly transaction between market participants at the measurement date. We apply fair value accounting for all financial assets and liabilities that are recognized or disclosed at fair value in the financial statements on a recurring basis. We measure cash and cash equivalents and short-term investments at fair value using a fair value hierarchy of inputs. We approximate fair value by using the carrying amounts for accounts receivable, accounts payable and accrued expenses due to their short-term nature.</div><div style="margin-bottom:12pt;text-indent:18pt">Investments</div><div style="margin-bottom:12pt;text-indent:18pt">We currently invest in commercial paper, corporate bonds, and U.S. treasury and agency obligations. Our investments are classified as available-for-sale and recorded at fair value, with unrealized gains and losses reported in accumulated other comprehensive income within stockholders’ equity (deficit).</div><div style="margin-bottom:12pt;text-indent:18pt">We evaluate potential impairments of available-for-sale debt securities due to credit-related and non-credit-related factors, including market risk, and if it is more-likely-than-not that we would have to sell the security before the recovery of the amortized cost basis. Identified credit-related impairments would be recognized as a charge in the statement of operations.</div><div style="margin-bottom:12pt;text-indent:18pt">Accounts Receivable</div><div style="margin-bottom:12pt;text-indent:18pt">Accounts receivable are recorded at the invoiced amount, less an allowance for doubtful accounts, and do not bear interest. We maintain an allowance for doubtful accounts at an amount estimated to be sufficient to cover the risk of collecting less than full payment of the receivables. At each balance sheet date, we evaluate our receivables and assess the allowance for doubtful accounts based on specific customer collection issues and historical write-off trends.</div><div style="margin-bottom:12pt;text-indent:18pt">Our allowance for doubtful accounts reflects our best estimate of expected future credit losses. We consider various factors that may impact our ability to collect on accounts receivable, including our historical collection experience, age of accounts receivable balances, current conditions, reasonable and supportable forecasts of future economic conditions, as well as other factors. However, given the uncertainty caused by the COVID-19 pandemic and other factors, these estimates may change and future credit losses may differ from our estimates. Expected credit losses from accounts receivable are recognized as expense in our statement of operations.</div><div style="margin-bottom:12pt;text-indent:18pt">Deferred Commissions</div><div style="margin-bottom:12pt;text-indent:18pt">Sales commissions, including related fringe benefit costs, are considered to be incremental costs of obtaining a contract. Sales commissions on initial sales are not commensurate with sales commissions on contract renewals and therefore are recognized over an estimated period of benefit, which ranges between <span style="-sec-ix-hidden:id3VybDovL2RvY3MudjEvZG9jOjUxNTlkNWZjMGNiNDQ4ZWFiYjdiMjdjMGFjMzI1YmViL3NlYzo1MTU5ZDVmYzBjYjQ0OGVhYmI3YjI3YzBhYzMyNWJlYl85Ny9mcmFnOjI3MDM1MGZlZDZhNDQ5ZjliMzIxZTYwZmYxMDgxNGM3L3RleHRyZWdpb246MjcwMzUwZmVkNmE0NDlmOWIzMjFlNjBmZjEwODE0YzdfMTIxMTk_af4b571c-825d-40cc-8134-1b873fdc6dc3">three and four years for subscription arrangements and five years for perpetual license arrangements. We estimated the period of benefit based on the expected contract term including renewal periods, the lifecycle of our technology, and other factors. Sales commissions on contract renewals are capitalized and amortized ratably over the contract term as part of sales and marketing expense, with the exception of contracts with renewal periods that are one year or less, in which case the incremental costs are expensed as incurred.</div><div style="margin-bottom:12pt;text-indent:18pt">Property and Equipment, net</div><div style="margin-bottom:12pt;text-indent:18pt">Property and equipment, net is stated at historical cost less accumulated depreciation. Depreciation is computed using the straight-line method over the estimated useful lives of the assets: three years for computer software and equipment and five years for furniture and fixtures. Leasehold improvements are amortized using the straight-line method over the shorter of the estimated useful lives of the assets or the terms of the respective leases. Property and equipment, net includes right-of-use assets acquired under finance leases. Amortization of assets acquired under finance leases is included in depreciation expense. Repairs and maintenance costs are expensed as incurred.</div><div style="margin-bottom:12pt;text-indent:18pt">Leases</div><div style="margin-bottom:12pt;text-indent:18pt">We determine if an arrangement contains a lease and the classification of that lease, if applicable, at inception. We have elected to not recognize a lease liability or right-of-use ("ROU") asset for short-term leases (leases with a term of twelve months or less). For contracts with lease and non-lease components, we have elected to not allocate the contract consideration, and account for the lease and non-lease components as a single lease component. Additionally, we enter into arrangements to use shared office spaces and other facilities, and have determined that these arrangements do not contain leases as we do not have the right to use an identified asset. Operating leases are included in operating lease ROU assets, operating lease liabilities and operating lease liabilities (net of current portion) in our consolidated balance sheets. Finance leases are included in property and equipment, other current liabilities and other liabilities in our consolidated balance sheets. </div><div style="margin-bottom:12pt;text-indent:18pt">ROU assets represent our right to use an underlying asset for the lease term and lease liabilities represent our obligation to make lease payments under the lease. Operating lease ROU assets and liabilities are recognized at the lease commencement date based on the present value of lease payments over the lease term. The implicit rate within our operating leases are generally not determinable and we use our incremental borrowing rate at the lease commencement date to determine the present value of lease payments. The determination of our incremental borrowing rate requires judgment. We determine our incremental borrowing rate for each lease using our current borrowing rate, adjusted for various factors including level of collateralization, term and currency to align with the terms of the lease. The operating lease ROU asset also includes any lease prepayments, offset by lease incentives. Certain of our leases include options to extend or terminate the lease. An option to extend the lease is considered in connection with determining the ROU asset and lease liability when it is reasonably certain we will exercise that option. An option to terminate is considered unless it is reasonably certain we will not exercise the option.</div><div style="margin-bottom:12pt;text-indent:18pt">Lease expense for lease payments is recognized on a straight-line basis over the term of the lease.</div><div style="margin-bottom:12pt;text-indent:18pt">Impairment of Long-Lived Assets</div><div style="margin-bottom:12pt;text-indent:18pt">We evaluate our long-lived assets for impairment whenever events or changes in circumstance indicate that the carrying amount may not be fully recoverable. Recoverability of the long-lived assets is measured by a comparison of the carrying amount of the assets to future undiscounted net cash flows expected to be generated by the assets. If such assets are considered to be impaired, the impairment to be recognized is measured as the excess of the carrying amount over the fair value. There was no impairment of long-lived assets in 2020, 2019 or 2018.</div><div style="margin-bottom:12pt;text-indent:18pt">Business Combinations</div><div style="margin-bottom:12pt;text-indent:18pt">We account for business combinations by recognizing the fair value of acquired assets and liabilities. The excess purchase consideration over the fair value of acquired assets and liabilities is recorded as goodwill. When determining the fair value of assets acquired and liabilities assumed, we make estimates and assumptions, especially with respect to intangible assets. Estimates in valuing certain identifiable intangible assets include, but are not limited to, projected revenue growth rates, future expected operating expenses, obsolescence projections and an appropriate discount rate. Our estimate of fair value is based upon assumptions we believe to be reasonable, but which are inherently uncertain and, as a result, actual results may differ from estimates. During the measurement period, we may make adjustments to the fair value of assets acquired and liabilities assumed, with offsetting adjustments to goodwill. Any adjustments made after the measurement period will be reflected in the consolidated statements of operations. Acquisition-related transaction costs are expensed as incurred.</div><div style="margin-bottom:12pt;text-indent:18pt">Goodwill</div><div style="margin-bottom:12pt;text-indent:18pt">The excess of the purchase consideration over the fair value of acquired assets and liabilities is recorded as goodwill. We perform our annual impairment assessment on October 1, or more frequently, when events or circumstances indicate impairment may have occurred. We operate as one reporting unit and have elected to first assess qualitative factors to determine whether it is more likely than not that the fair value of the Company as a whole is less than its carrying amount, including goodwill. The qualitative assessment includes an evaluation of relevant events and circumstances, including macroeconomic, industry and market conditions, our overall financial performance, and trends in the value of our common stock. During the periods presented, there were no indications of impairment and it was not more likely than not that goodwill was impaired.</div><div style="margin-bottom:12pt;text-indent:18pt">Advertising</div><div style="margin-bottom:12pt;text-indent:18pt">Advertising costs are expensed as they are incurred. We incurred advertising costs of $8.2 million, $5.3 million and $3.3 million in 2020, 2019 and 2018, respectively, which are included in sales and marketing expense in the consolidated statements of operations.</div><div style="margin-bottom:12pt;text-indent:18pt">Software Development Costs</div><div style="margin-bottom:12pt;text-indent:18pt">Research and development costs to develop software to be sold, leased or marketed are expensed as incurred up to the point of technological feasibility for the related software product. We have not capitalized development costs for software to be sold, leased or marketed to date, as the software development process is essentially completed concurrent with the establishment of technological feasibility. As such, these costs are expensed as incurred and recognized in research and development costs in the consolidated statements of operations.</div><div style="margin-bottom:12pt;text-indent:18pt">Software developed for internal use, with no substantive plans to market such software at the time of development, are capitalized and included in property and equipment, net in the consolidated balance sheets. Costs incurred during the preliminary planning and evaluation and post implementation stages of the project are expensed as incurred. Costs incurred during the application development stage of the project are capitalized. In 2020, 2019 and 2018, we capitalized $1.6 million, $4.2 million and $2.4 million, respectively, of development costs related to internal use software.</div><div style="margin-bottom:12pt;text-indent:18pt">Stock-Based Compensation</div><div style="margin-bottom:12pt;text-indent:18pt">Stock-based compensation expense related to our restricted stock units ("RSUs"), purchase rights issued under our </div><div style="margin-bottom:12pt">2018 Employee Stock Purchase Plan ("2018 ESPP"), stock options and restricted stock is calculated based on the fair value of the awards granted and is recognized on a straight-line basis over the requisite service period, which is generally <span style="-sec-ix-hidden:id3VybDovL2RvY3MudjEvZG9jOjUxNTlkNWZjMGNiNDQ4ZWFiYjdiMjdjMGFjMzI1YmViL3NlYzo1MTU5ZDVmYzBjYjQ0OGVhYmI3YjI3YzBhYzMyNWJlYl85Ny9mcmFnOjI3MDM1MGZlZDZhNDQ5ZjliMzIxZTYwZmYxMDgxNGM3L3RleHRyZWdpb246MjcwMzUwZmVkNmE0NDlmOWIzMjFlNjBmZjEwODE0YzdfMzg0ODI5MDc0MjMxNQ_9ccac568-4c12-420e-953a-d21ae19eef1b">two to four years. RSUs that include performance-based vesting conditions and are expensed using the accelerated attribution method. We account for forfeitures as they occur.</div><div style="margin-bottom:12pt;text-indent:18pt">The fair value of RSUs is based on the estimated fair value of our common stock on the date of grant. The fair value of stock options and 2018 ESPP purchase rights is estimated on the grant date using the Black-Scholes option pricing model, which requires us to make assumptions and judgments, including the expected term, expected volatility, and risk-free interest rates. Prior to our IPO, we estimated the fair value of our common stock at the date of grant. Following our IPO, we use the market price of our common stock at the date of grant. </div><div style="margin-bottom:12pt;text-indent:18pt">Net Loss per Share</div><div style="margin-bottom:12pt;text-indent:18pt">We calculate basic and diluted net loss per share attributable to common stockholders in conformity with the two-class method required for participating securities. Under the two-class method, the net loss attributable to common stockholders is not allocated to the redeemable convertible preferred stock as the holders of our redeemable convertible preferred stock do not have a contractual obligation to share in losses.</div><div style="margin-bottom:12pt;text-indent:18pt">Under the two-class method, basic net loss per share attributable to common stockholders is computed by dividing the net loss attributable to common stockholders by the weighted-average number of shares of common stock outstanding during the period. Net loss attributable to common stockholders is calculated by adjusting net loss by the current period accretion of redeemable convertible preferred stock.</div><div style="margin-bottom:12pt;text-indent:18pt">Upon the completion of our IPO, all of our Series A and Series B redeemable convertible preferred stock automatically converted into shares of our common stock. </div><div style="margin-bottom:12pt;text-indent:18pt">Diluted earnings per share attributable to common stockholders is computed by giving effect to all potentially dilutive common stock equivalents in the period, including unvested RSUs, stock options, unvested restricted shares, redeemable convertible preferred stock and shares to be issued under our 2018 ESPP. As we have reported losses for all periods presented, all potentially dilutive securities have been excluded from the calculation of diluted net loss per share attributable to common stockholders as their effect would be antidilutive.</div><div style="margin-bottom:12pt;text-indent:18pt">Segment Information</div><div style="margin-bottom:12pt;text-indent:18pt">We operate as one operating segment as our chief executive officer, who is our chief operating decision maker, reviews financial information on a consolidated basis for purposes of making operating decisions, allocating resources, and evaluating financial performance.</div><div style="margin-bottom:12pt;text-indent:18pt">Income Taxes</div><div style="margin-bottom:12pt;text-indent:18pt">Income taxes are accounted for under the asset and liability method. This method requires recognition of deferred tax assets and liabilities for the expected future tax consequences of temporary differences between the financial statement carrying amounts and the tax basis of existing assets and liabilities, net operating loss carryforwards, and tax credit carryforwards. A valuation allowance is provided if it is more likely than not that some or all of the deferred tax assets will not be realized.</div><div style="margin-bottom:12pt;text-indent:18pt">We recognize tax benefits from an uncertain tax position if it is more likely than not to be sustained upon audit by the relevant taxing authority. Interest and penalties associated with such uncertain tax positions are classified as a component of income tax expense.</div><div style="margin-bottom:12pt;text-indent:18pt">Recently Adopted Accounting Pronouncements</div><div style="margin-bottom:12pt;text-indent:18pt">We adopted Accounting Standards Update ("ASU") No. 2016-13 — Financial Instruments-Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments, effective January 1, 2020 using the modified retrospective approach. The new standard replaces the previous incurred loss impairment methodology with a methodology that reflects </div><div style="margin-bottom:12pt">current expected credit losses for financial assets, including trade receivables, which are not measured at fair value, through net income.

<div style="margin-bottom:12pt;text-indent:18pt">Revenue Recognition</div><div style="margin-bottom:3pt;text-indent:18pt">We recognize revenue in order to depict the transfer of promised goods or services to customers in an amount that reflects the consideration we expect to be entitled in exchange for those goods or services. To achieve this, we apply the following steps:</div><div style="margin-bottom:3pt;padding-left:36pt;text-indent:-18pt">•Identify the contract with a customer</div><div style="margin-bottom:3pt;padding-left:36pt;text-indent:-18pt">•Identify the performance obligations in the contract</div><div style="margin-bottom:3pt;padding-left:36pt;text-indent:-18pt">•Determine the transaction price</div><div style="margin-bottom:3pt;padding-left:36pt;text-indent:-18pt">•Allocate the transaction price to the performance obligations in the contract</div><div style="margin-bottom:12pt;padding-left:36pt;text-indent:-18pt">•Recognize revenue when or as performance obligations are satisfied</div><div style="margin-bottom:12pt;text-indent:18pt">In situations where we enter into a contractual arrangement that includes non-standard terms and conditions, such as acceptance provisions or options to purchase additional products and services, as well as contract modifications, we apply judgment in identifying and assessing the impact on revenue recognition. </div><div style="margin-bottom:12pt;text-indent:18pt">We generate revenue from subscription arrangements for software and cloud-based solutions, perpetual licenses, maintenance associated with perpetual licenses, and professional services and other revenue. We begin to recognize revenue when control of our software or services is transferred to the customer, which for sales made through distributors is concurrent with the transfer to the end user.</div><div style="margin-bottom:12pt;text-indent:18pt">Subscription Revenue </div><div style="margin-bottom:12pt;text-indent:18pt">Subscription arrangements generally have annual or multi-year contractual terms and allow customers to use our software or cloud solutions, including ongoing software updates and the ability to identify the latest cybersecurity vulnerabilities. Revenue is recognized ratably over the subscription term given the critical utility provided by the ongoing updates that are released throughout the contract period. </div><div style="margin-bottom:12pt;text-indent:18pt">Perpetual License and Maintenance Revenue </div><div style="margin-bottom:12pt;text-indent:18pt">Our perpetual licenses are generally sold with one or more years of maintenance, which include ongoing software updates and the ongoing ability to identify the latest cybersecurity vulnerabilities. Given the critical utility provided by the ongoing software updates and updated ability to identify network vulnerabilities included in maintenance, we combine the perpetual license and the maintenance into a single performance obligation. Perpetual license arrangements generally contain a material right related to the customer’s ability to renew maintenance at a price that is less than the initial license fee. We apply a practical alternative to allocating a portion of the transaction price to the material right performance obligation and estimate a hypothetical transaction price which includes fees for expected maintenance renewals based on the estimated economic life of the perpetual license contracts. We allocate the transaction price between the cybersecurity subscription provided in the initial contract and the material right related to expected contract renewals based on the hypothetical transaction price. We recognize the amount allocated to the combined license and maintenance performance obligation over the initial contractual period, which is generally one year. We recognize the amount allocated to the material right over the expected maintenance renewal period, which begins at the end of the initial contractual term and is generally four years. We have estimated the five-year economic life of perpetual license contracts based on historical contract attrition, expected renewal periods, the lifecycle of the our technology and other factors. While we believe that the estimates we have made are reasonable and appropriate, different assumptions and estimates could materially impact our reported financial results.</div><div style="margin-bottom:12pt;text-indent:18pt">Professional Services and Other Revenue </div><div style="margin-bottom:12pt;text-indent:18pt">Professional services and other revenue is primarily comprised of advisory services and training related to the deployment and optimization of our products. These services do not result in significant customization of our products. Professional services and other revenue is recognized as the services are performed. </div><div style="margin-bottom:12pt;text-indent:18pt">Contracts with Multiple Performance Obligations </div><div style="margin-bottom:12pt;text-indent:18pt">In cases where our contracts with customers contain multiple performance obligations, the contract transaction price is allocated on a relative standalone selling price basis. We typically determine standalone selling price based on observable selling prices of our products and services. </div><div style="margin-bottom:12pt;text-indent:18pt">Variable Consideration </div><div style="margin-bottom:12pt;text-indent:18pt">We record revenue from sales at the net sales price, which is the transaction price, including estimates of variable consideration when applicable. Certain of our customers may be entitled to receive credits and in certain circumstances, refunds, if service level commitments are not met. We have not historically experienced significant incidents affecting the ability to meet these service level commitments and any estimated refunds related to these agreements have not been material. </div><div style="margin-bottom:12pt;text-indent:18pt">Sales through our channel network of distributors and resellers are generally discounted as compared to the price that we would sell to an end user.

The 2020 Credit Facility includes a $45.0 million uncommitted expansion, as well as a $10.0 million sublimit for the issuance of letters of credit and a swingline sub-facility of up to $10.0 million, and has a financial covenant requiring a minimum consolidated quick ratio of at least 1.5:1.0 on the last day of each quarter.</div><div style="margin-bottom:12pt;text-indent:18pt">In 2020 and 2019, there were no amounts outstanding under our 2020 Credit Facility or, prior to its expiration, the 2017 Credit Facility.

In 2018, we granted stock options to employees that had a per share weighted average grant date fair value of $6.84.

Contemporaneous third-party valuations were obtained to assist in determining the fair value of our common stock.
