| Organization, Consolidation and Presentation of Financial Statements [Abstract] | |
| 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. |
| Consolidation | All intercompany accounts and transactions have been eliminated in consolidation. |
| 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 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.

| Segment Information | Segment Information We operate as one operating segment. Our chief operating decision makers ("CODMs") are our Co-Chief Executive Officers. Our CODMs review financial information on a consolidated basis for purposes of making operating decisions, allocating resources and evaluating financial performance. Our CODMs review cost of sales expense, sales and marketing expense, research and development expense and general and administrative expense to assess our significant segment expenses, and review income (loss) from operations and net income (loss) to assess our operating performance. Our CODMs also review total assets, as reported on our consolidated balance sheets. See our consolidated statement of operations for our significant segment expenses, income (loss) from operations and net income (loss) in the periods presented.

| Recently Adopted Accounting Pronouncements and Recently Issued Accounting Pronouncements | Recently Adopted Accounting Pronouncements In July 2025, the FASB issued ASU 2025-05 - Measurement of Credit Loss for Accounts Receivable and Contract Assets, which provides a practical expedient for the calculation of current expected credit losses for accounts receivable and contract assets, allowing entities to assume that current conditions as of the balance sheet date will persist through the forecast period. The adoption of ASU 2025-05 as of January 1, 2026 on a prospective basis had an immaterial impact on our consolidated financial statements. Recently Issued Accounting Pronouncements In November 2024, the FASB issued ASU 2024-03 - Income Statement - Reporting Comprehensive Income - Expense Disaggregation Disclosures (Subtopic 220-40): Disaggregation of Income Statement Expenses, which requires public entities to disclose, on an annual and interim basis, disaggregated information about certain income statement expense line items. The ASU also requires disclosure of the total amount of selling expenses recognized in continuing operations on an annual and interim basis and disclosure of the definition of selling expenses. The guidance is effective beginning January 1, 2027 on a prospective basis, with a retrospective option, and interim reporting periods beginning on January 1, 2028. Early adoption is permitted. We are currently evaluating the impact of adopting this standard on our consolidated financial statements and disclosures. In September 2025, the FASB issued ASU 2025-06 - Targeted Improvements to the Accounting for Internal-Use Software, which clarifies the requirements for capitalizing internal use software. The guidance is effective beginning January 1, 2028 using a prospective, modified retrospective or full retrospective approach. We are currently evaluating the impact of adopting this standard on our consolidated financial statements and disclosures. In December 2025, the FASB issued ASU 2025-10 - Government Grants (Topic 832): Accounting for Government Grants Received by Business Entities, establishing guidance on the recognition, measurement and presentation of government grants. The guidance is effective beginning January 1, 2029 on a modified prospective, modified retrospective or retrospective basis, with early adoption permitted. We are currently evaluating the impact of adopting this standard on our consolidated financial statements and disclosures.
