Organization, Consolidation and Presentation of Financial Statements [Abstract]
Business and Summary of Significant Accounting Policies	Business and Summary of Significant Accounting Policies Business Description Tenable Holdings, Inc. (the “Company,” “we,” "us," or “our”) is a provider of exposure management solutions. Exposure management is an effective discipline for measuring, comparing and reducing cybersecurity risk in today's complex IT environments. Our solutions 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, Active Directory and industrial internet of things and operational technology environments. Basis of Presentation 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”) for interim financial information. All intercompany accounts and transactions have been eliminated in consolidation. The consolidated statements are unaudited and should be read in conjunction with the consolidated financial statements and related notes included in our 2023 Annual Report on Form 10-K ("10-K") filed with the Securities and Exchange Commission on February 28, 2024. The consolidated financial statements have been prepared on a basis consistent with the audited annual consolidated financial statements included in the 10-K and, in the opinion of management, include all adjustments of a normal recurring nature necessary to fairly state our financial position, our results of operations, and cash flows. The results for the three months ended March 31, 2024 are not necessarily indicative of the operating results expected for the year ending December 31, 2024 or any other future period. Use of Estimates 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, the incremental borrowing rate for operating leases, and the valuation of deferred tax assets and investments. 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. Significant Accounting Policies Our significant accounting policies are described in our 10-K. During the three months ended March 31, 2024, there were no material changes to our significant accounting policies from those described in our 10-K. Recently Issued Accounting Pronouncements In November 2023, the Financial Accounting Standards Board (“FASB”) issued ASU 2023-07 - Segment Reporting (Topic 280): Improvements to Reportable Segment Disclosures, which requires public entities with a single reportable segment to provide all the disclosures required by this standard and all existing segment disclosures in Topic 280 on an interim and annual basis, including new requirements to disclose significant segment expenses that are regularly provided to the Chief Operating Decision Maker ("CODM") and included within the reported measure(s) of a segment's profit or loss, the amount and composition of any other segment items, the title and position of the CODM, and how the CODM uses the reported measure(s) of a segment's profit or loss to assess performance and decide how to allocate resources. The guidance is effective for our annual period beginning January 1, 2025, and interim periods thereafter, applied retrospectively with early adoption permitted. We are currently evaluating the impact of adoption of this standard on our consolidated financial statements and disclosures. In December 2023, the FASB issued ASU 2023-09 - Income Taxes (Topic 740): Improvements to Income Tax Disclosures, which requires public entities to provide greater disaggregation within their annual rate reconciliation, including new requirements to present reconciling items on a gross basis in specified categories, disclose both percentages and dollar amounts, and disaggregate individual reconciling items by jurisdiction and nature when the effect of the items meet a quantitative threshold. The guidance also requires disaggregating the annual disclosure of income taxes paid, net of refunds received, by federal (national), state, and foreign taxes, with separate presentation of individual jurisdictions that meet a quantitative threshold. The guidance is effective for our annual periods beginning January 1, 2025 on a prospective basis, with a retrospective option, and early adoption is permitted. We are currently evaluating the impact of adoption of this standard on our consolidated financial statements and disclosures.

Revenue from Contract with Customer [Abstract]
Revenue	Revenue Disaggregation of Revenue The following table presents a summary of revenue: Three Months Ended March 31, (in thousands) 2024 2023 Subscription revenue $ 197,635 $ 171,098 Perpetual license and maintenance revenue 12,156 12,181 Professional services and other revenue 6,170 5,560 Revenue $ 215,961 $ 188,839 Concentrations We sell and market our products and services through our field sales force that works closely with our channel partners, which includes a network of distributors and resellers, in developing sales opportunities. We use a two-tiered channel model whereby we sell our products and services to our distributors, which in turn sell to resellers, which then sell to end-users. Revenue derived through our channel network comprised 93% of revenue in the three months ended March 31, 2024 and 2023. One of our distributors accounted for 34% of revenue in the three months ended March 31, 2024 and 37% of revenue in the three months ended March 31, 2023. That same distributor accounted for 32% of accounts receivable at March 31, 2024 and December 31, 2023. Contract Balances We generally bill our customers in advance and accounts receivable are recorded when we have the right to invoice the customer. Contract liabilities consist of deferred revenue and include customer billings and payments received in advance of performance under the contract. In the three months ended March 31, 2024 and 2023, we recognized revenue of $201.0 million and $174.0 million, respectively, that was included in the deferred revenue balance at the beginning of the respective periods. Remaining Performance Obligations At March 31, 2024, the future estimated revenue related to unsatisfied performance obligations was $742.4 million, of which $572.9 million is expected to be recognized as revenue over the next twelve months, and the remainder is expected to be recognized over the four years thereafter. Deferred Commissions The following summarizes the activity of deferred incremental costs of obtaining a contract: Three Months Ended March 31, (in thousands) 2024 2023 Beginning balance $ 121,953 $ 111,508 Capitalization of contract acquisition costs 9,035 8,907 Amortization of deferred contract acquisition costs (13,373) (12,035) Ending balance $ 117,615 $ 108,380

At March 31, 2024 and December 31, 2023, our unrealized losses were due to rising market interest rates compared to when the investments were initiated. We do not believe any unrealized losses represent credit losses, and it is unlikely we would sell the investments before we would recover their amortized cost basis. The contractual maturities of our short-term investments are as follows: March 31, 2024 December 31, 2023 (in thousands) Amortized Cost Estimated Fair Value Amortized Cost Estimated Fair Value Due within one year $ 212,522 $ 212,368 $ 219,437 $ 219,414 Due between one and two years 38,457 38,426 17,365 17,426 Total short-term investments $ 250,979 $ 250,794 $ 236,802 $ 236,840 At March 31, 2024 and December 31, 2023, cash and cash equivalents included $5.9 million and $5.8 million, respectively, of restricted cash primarily related to collateral for our outstanding letters of credit.

Fair Value Disclosures [Abstract]
Fair Value Measurements	Fair Value Measurements We measure certain financial instruments at fair value using a fair value hierarchy. In the hierarchy, assets are classified based on the lowest level inputs used in valuation into the following categories: • Level 1 — Quoted prices in active markets for identical assets and liabilities; • Level 2 — Observable inputs including quoted market prices for similar assets and liabilities in active markets, quoted prices for identical assets and liabilities in inactive markets, or inputs that are corroborated by observable market data; and • Level 3 — Unobservable inputs. The following tables summarize assets that are measured at fair value on a recurring basis: March 31, 2024 (in thousands) Level 1 Level 2 Level 3 Total Cash equivalents Money market funds $ 151,173 $ — $ — $ 151,173 Total cash equivalents $ 151,173 $ — $ — $ 151,173 Short-term investments Commercial paper $ — $ 78,345 $ — $ 78,345 Corporate bonds — 70,027 — 70,027 Asset backed securities — 18,514 — 18,514 Yankee bonds — 8,901 — 8,901 U.S. Treasury and agency obligations — 75,007 — 75,007 Total short-term investments $ — $ 250,794 $ — $ 250,794 December 31, 2023 (in thousands) Level 1 Level 2 Level 3 Total Cash equivalents Money market funds $ 130,375 $ — $ — $ 130,375 Total cash equivalents $ 130,375 $ — $ — $ 130,375 Short-term investments Commercial paper $ — $ 82,216 $ — $ 82,216 Corporate bonds — 61,149 — 61,149 Asset backed securities — 15,043 — 15,043 Yankee bonds — 6,913 — 6,913 U.S. Treasury and agency obligations — 71,519 — 71,519 Total short-term investments $ — $ 236,840 $ — $ 236,840 At March 31, 2024 and December 31, 2023, we had $5.9 million and $9.4 million, respectively, of SAFE investments with privately held companies, which are included in other assets on our consolidated balance sheets. We record our SAFE investments at cost, less any impairment, plus or minus observable price changes for similar investments of the same issuer. During the three months ended March 31, 2024, we received $3.5 million in proceeds from one of our SAFE investments and expect to collect the remaining $0.9 million once escrow funds have been released. No material events impacted the carrying value of our SAFE investments in the three months ended March 31, 2024 and 2023. We did not have any liabilities measured and recorded at fair value on a recurring basis at March 31, 2024 and December 31, 2023.

The table below summarizes the carrying value of the Term Loan: (in thousands) March 31, 2024 Term loan $ 366,562 Less: Unamortized debt discount and issuance costs (5,286) Term loan, net of issuance costs 361,276 Less: Term loan, net, current (1) (2,654) Term loan, net of issuance costs (net of current portion) $ 358,622 _______________ (1) Term loan, net current is included in other current liabilities on our consolidated balance sheets. The Term Loan bears interest at a rate of 2.75% per annum over the Secured Overnight Financing Rate ("SOFR"), subject to a 0.50% floor, plus a credit spread adjustment depending on the interest period. The Term Loan is being amortized at 1% per annum in equal quarterly installments until the final payment of $350.6 million on the July 7, 2028 maturity date. Our Term Loan is recorded at its carrying value. At March 31, 2024, the fair value of our Term Loan was approximately $366.1 million. In the fair value hierarchy, our Term Loan is classified as Level 2 as it is traded in less active markets. The maturities of the Term Loan at March 31, 2024 were as follows: (in thousands) Year ending December 31, 2024 (1) $ 2,812 2025 3,750 2026 3,750 2027 3,750 2028 352,500 Total $ 366,562 _______________ (1) Represents the nine months ending December 31, 2024. We may be subject to mandatory Term Loan prepayments related to the excess cash flow provisions. These prepayments would only be required if our first lien net leverage ratio (as defined in our Credit Agreement) exceeds 3.5 at the end of each year. At March 31, 2024, our first lien net leverage ratio was 1.14. The Revolving Credit Facility bears interest at a rate, depending on first lien net leverage, ranging from 2.00% to 2.50% over SOFR and matures on July 7, 2026. Additionally, we pay a commitment fee during the term ranging from 0.25% to 0.375% per annum of the average daily undrawn portion of the revolving commitments based on the first lien net leverage ratio. The Revolving Credit Facility contains a $15.0 million letter of credit sublimit. At March 31, 2024, we had $0.2 million of standby letters of credit outstanding under our Revolving Credit Facility related to one of our operating leases. At March 31, 2024, we were in compliance with the covenants under the Credit Agreement.

Organization, Consolidation and Presentation of Financial Statements [Abstract]
Consolidations	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”) for interim financial information. All intercompany accounts and transactions have been eliminated in consolidation.
Basis of Accounting	The consolidated statements are unaudited and should be read in conjunction with the consolidated financial statements and related notes included in our 2023 Annual Report on Form 10-K ("10-K") filed with the Securities and Exchange Commission on February 28, 2024. The consolidated financial statements have been prepared on a basis consistent with the audited annual consolidated financial statements included in the 10-K and, in the opinion of management, include all adjustments of a normal recurring nature necessary to fairly state our financial position, our results of operations, and cash flows.
Use of Estimates	Use of Estimates 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, the incremental borrowing rate for operating leases, and the valuation of deferred tax assets and investments. 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.
Recently Issued Accounting Pronouncements	Recently Issued Accounting Pronouncements In November 2023, the Financial Accounting Standards Board (“FASB”) issued ASU 2023-07 - Segment Reporting (Topic 280): Improvements to Reportable Segment Disclosures, which requires public entities with a single reportable segment to provide all the disclosures required by this standard and all existing segment disclosures in Topic 280 on an interim and annual basis, including new requirements to disclose significant segment expenses that are regularly provided to the Chief Operating Decision Maker ("CODM") and included within the reported measure(s) of a segment's profit or loss, the amount and composition of any other segment items, the title and position of the CODM, and how the CODM uses the reported measure(s) of a segment's profit or loss to assess performance and decide how to allocate resources. The guidance is effective for our annual period beginning January 1, 2025, and interim periods thereafter, applied retrospectively with early adoption permitted. We are currently evaluating the impact of adoption of this standard on our consolidated financial statements and disclosures. In December 2023, the FASB issued ASU 2023-09 - Income Taxes (Topic 740): Improvements to Income Tax Disclosures, which requires public entities to provide greater disaggregation within their annual rate reconciliation, including new requirements to present reconciling items on a gross basis in specified categories, disclose both percentages and dollar amounts, and disaggregate individual reconciling items by jurisdiction and nature when the effect of the items meet a quantitative threshold. The guidance also requires disaggregating the annual disclosure of income taxes paid, net of refunds received, by federal (national), state, and foreign taxes, with separate presentation of individual jurisdictions that meet a quantitative threshold. The guidance is effective for our annual periods beginning January 1, 2025 on a prospective basis, with a retrospective option, and early adoption is permitted. We are currently evaluating the impact of adoption of this standard on our consolidated financial statements and disclosures.
