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 Cyber Exposure Management 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, 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 2021 Annual Report on Form 10-K ("10-K") filed with the Securities and Exchange Commission on February 25, 2022. 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 and six months ended June 30, 2022 are not necessarily indicative of the operating results expected for the year ending December 31, 2022 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. 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 six months ended June 30, 2022, there were no material changes to our significant accounting policies from those described in our 10-K. Recently Issued Accounting Pronouncements In March 2020, the Financial Accounting Standards Board ("FASB") issued ASU No. 2020-04 - Reference Rate Reform (Topic 848): Facilitation of the Effects of Reference Rate Reform on Financial Reporting . This ASU provides optional expedients and exceptions to contract modification guidance to ease the financial reporting burden of the transition from the London Interbank Offered Rate ("LIBOR") to alternative reference rates. The ASU was effective beginning on March 12, 2020 and can be adopted prospectively through December 31, 2022. We do not expect the impact of adopting this standard to be material for our consolidated financial statements.

Revenue	Revenue Disaggregation of Revenue The following table presents a summary of revenue: Three Months Ended June 30, Six Months Ended June 30, (in thousands) 2022 2021 2022 2021 Subscription revenue $ 146,806 $ 114,167 $ 289,493 $ 221,569 Perpetual license and maintenance revenue 12,683 12,567 25,556 24,972 Professional services and other revenue 4,852 3,525 8,660 6,907 Revenue $ 164,341 $ 130,259 $ 323,709 $ 253,448 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. We derived 92% of revenue through our channel network in the three and six months ended June 30, 2022 and 2021. One of our distributors accounted for 38% of revenue in the three and six months ended June 30, 2022 and 40% of revenue in the three and six months ended June 30, 2021. That same distributor accounted for 34% and 32% of accounts receivable at June 30, 2022 and December 31, 2021, respectively. 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 June 30, 2022 and 2021 and the six months ended June 30, 2022 and 2021, we recognized revenue of $148.2 million, $119.0 million, $260.6 million and $210.5 million, respectively, that was included in the deferred revenue balance at the beginning of each of the respective periods. Remaining Performance Obligations At June 30, 2022, the future estimated revenue related to unsatisfied performance obligations was $567.7 million, of which approximately 75% is expected to be recognized as revenue over the succeeding 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 June 30, Six Months Ended June 30, (in thousands) 2022 2021 2022 2021 Beginning balance $ 99,263 $ 77,300 $ 99,949 $ 78,876 Capitalization of contract acquisition costs 12,073 10,222 22,403 17,446 Amortization of deferred contract acquisition costs (11,336) (9,025) (22,352) (17,825) Ending balance $ 100,000 $ 78,497 $ 100,000 $ 78,497

At June 30, 2022, 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: June 30, 2022 (in thousands) Amortized Cost Estimated Fair Value Due within one year $ 234,088 $ 232,468 Due between one and two years 10,815 10,579 Total short-term investments $ 244,903 $ 243,047 At June 30, 2022 and December 31, 2021, cash and cash equivalents included $5.8 million of restricted cash primarily related to collateral for our outstanding letters of credit and excluded $0.3 million of restricted cash related to an account established as collateral for a lease arrangement, which is included in other assets on the consolidated balance sheets.

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: June 30, 2022 (in thousands) Level 1 Level 2 Level 3 Total Cash equivalents Money market funds $ 155,012 $ — $ — $ 155,012 Total cash equivalents $ 155,012 $ — $ — $ 155,012 Short-term investments Commercial paper $ — $ 107,498 $ — $ 107,498 Corporate bonds — 45,520 — 45,520 Asset backed securities — 21,245 — 21,245 Certificates of deposit — 19,978 — 19,978 Supranational bonds — 8,442 — 8,442 U.S. Treasury and agency obligations — 40,364 — 40,364 Total short-term investments $ — $ 243,047 $ — $ 243,047 December 31, 2021 (in thousands) Level 1 Level 2 Level 3 Total Cash equivalents Money market funds $ 178,518 $ — $ — $ 178,518 Total cash equivalents $ 178,518 $ — $ — $ 178,518 Short-term investments Commercial paper $ — $ 134,118 $ — $ 134,118 Corporate bonds — 27,128 — 27,128 Asset backed securities — 27,411 — 27,411 Certificates of deposit — 9,992 — 9,992 Supranational bonds — 8,599 — 8,599 U.S. Treasury and agency obligations — 27,044 — 27,044 Total short-term investments $ — $ 234,292 $ — $ 234,292 We did not have any liabilities measured and recorded at fair value on a recurring basis at June 30, 2022 and December 31, 2021.

Acquisitions, Goodwill and Intangible Assets	Acquisitions, Goodwill and Intangible Assets Business Combinations In June 2022, we acquired Bit Discovery, a leader in external attack surface management (EASM). Adding Bit Discovery's EASM capabilities to our solutions provides customers with a comprehensive view of their attack surface and helps identify and eliminate areas of risk. We acquired 100% of Bit Discovery's equity for $44.0 million in cash, net of cash acquired of $2.2 million, through a share purchase agreement. In February 2022, we acquired Cymptom, a platform that proactively measures, maps and prioritizes probable attack paths, and enables security teams to preemptively focus response ahead of and during breaches. Through a share purchase agreement, we acquired 100% of Cymptom's equity in exchange for cash consideration, net of cash acquired, for $23.0 million. Cash consideration, net of cash acquired, was preliminarily allocated as follows: (in thousands) Bit Discovery Cymptom Intangible assets $ 11,100 $ 4,113 Goodwill 36,213 18,960 Deferred tax (liabilities) assets, net (2,501) 128 Other liabilities, net (779) (241) Total purchase price $ 44,033 $ 22,960 We are still finalizing the allocations of the purchase price, which may change as additional information becomes available related to acquired intangible assets, working capital and income taxes for Bit Discovery and income taxes for Cymptom.

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 June 30, 2022, the fair value of our Term Loan was approximately $353 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 June 30, 2022 were as follows: (in thousands) Year ending December 31, 2022 (1) $ 1,875 2023 3,750 2024 3,750 2025 3,750 2026 3,750 Thereafter 356,250 Total $ 373,125 _______________ (1) Represents the six months ending December 31, 2022. We may be subject to mandatory Term Loan prepayments related to the excess cash flow provisions beginning in 2023. These prepayments would only be required if our first lien net leverage ratio (as defined in our Credit Agreement) exceeds 3.5, and at June 30, 2022, our first lien net leverage ratio was below that threshold. The Revolving Credit Facility bears interest at a rate, depending on first lien net leverage, ranging from 2.00% to 2.50% over LIBOR and matures on July 7, 2026. Additionally, we will 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. Since its inception, there have been no amounts outstanding under the Revolving Credit Facility. At June 30, 2022, 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 2021 Annual Report on Form 10-K ("10-K") filed with the Securities and Exchange Commission on February 25, 2022. 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. 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 March 2020, the Financial Accounting Standards Board ("FASB") issued ASU No. 2020-04 - Reference Rate Reform (Topic 848): Facilitation of the Effects of Reference Rate Reform on Financial Reporting . This ASU provides optional expedients and exceptions to contract modification guidance to ease the financial reporting burden of the transition from the London Interbank Offered Rate ("LIBOR") to alternative reference rates. The ASU was effective beginning on March 12, 2020 and can be adopted prospectively through December 31, 2022. We do not expect the impact of adopting this standard to be material for our consolidated financial statements.
