Description of Business and Summary of Significant Accounting Policies	Description of Business and Summary of Significant Accounting Policies Description of Business Qualys, Inc. (the "Company", "we", "us", "our") was incorporated in the state of Delaware on December 30, 1999. The Company is headquartered in Foster City, California and has wholly-owned subsidiaries throughout the world. The Company is a leading provider of cloud-based information technology ("IT"), security and compliance solutions that enable organizations to identify security risks to their IT infrastructures, help protect their IT systems and applications from ever-evolving cyber-attacks and achieve compliance with internal policies and external regulations. The Company’s cloud solutions address the growing security and compliance complexities and risks that are amplified by the dissolving boundaries between internal and external IT infrastructures and web environments, the rapid adoption of cloud computing and the proliferation of geographically dispersed IT assets. Organizations can use the Company’s integrated suite of solutions delivered on Qualys' Enterprise TruRisk Platform to cost-effectively obtain a unified view of their security and compliance posture across globally-distributed IT infrastructures. Basis of Presentation The accompanying unaudited condensed consolidated financial statements and condensed footnotes have been prepared in accordance with accounting principles generally accepted in the United States ("U.S. GAAP") for interim financial information as well as the instructions to Form 10-Q and the rules and regulations of the U.S. Securities and Exchange Commission ("SEC"). Certain information and disclosures normally included in the financial statements prepared in accordance with U.S. GAAP have been condensed or omitted pursuant to such rules and regulations. The condensed consolidated balance sheet as of December 31, 2024, included herein, was derived from the audited financial statements as of that date but does not include all disclosures, including notes required by U.S. GAAP. In the opinion of management, the accompanying unaudited condensed consolidated financial statements reflect all adjustments, which include only normal recurring adjustments, necessary for the fair statement of the financial position, results of operations and cash flows for the interim periods. The results of operations for the three months ended March 31, 2025 are not necessarily indicative of the results of operations expected for the entire year ending December 31, 2025 or for any other future annual or interim periods. These condensed consolidated financial statements should be read in conjunction with the consolidated financial statements and related notes included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2024 filed with the SEC on February 21, 2025. Use of Estimates The preparation of the unaudited condensed consolidated financial statements in conformity with U.S. GAAP requires management to make certain estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of assets and liabilities at the date of the condensed consolidated financial statements and the reported results of operations during the reporting period. The Company’s management regularly assesses these estimates, which primarily affect revenue recognition, allowance for credit loss, the valuation of goodwill and intangible assets, leases, stock-based compensation and income tax provision. Actual results could differ from those estimates and such differences may be material to the accompanying unaudited condensed consolidated financial statements. Recently Adopted Accounting Pronouncements None. Recently Issued Accounting Pronouncements Not Yet Adopted In December 2023, the FASB issued ASU 2023-09 - Improvements to Income Tax Disclosures, requiring improvements to income tax disclosures. The new ASU requires disclosure of disaggregated information about the effective tax rate and income taxes paid. The requirements of the ASU are effective for annual periods beginning after December 15, 2024 and are to be applied on a prospective basis. The Company's annual reporting requirements will be effective for fiscal year 2025. Companies can choose to early adopt and apply the guidance retrospectively. The Company is in the process of analyzing the impact of the ASU on related disclosures. 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, requiring more detailed information about the types of expenses included in certain expense captions presented on the consolidated statements of operations. Additionally, this amendment requires the disclosure of a qualitative description of the amounts remaining in relevant expense captions that are not separately disaggregated quantitatively and the disclosure of the total amount of selling expenses. The requirements of the ASU are effective for annual periods beginning after December 15, 2026, and for interim periods within fiscal years beginning after December 15, 2027 and are to be applied on a retrospective or prospective basis, with early adoption permitted. The Company's annual reporting requirements will be effective for fiscal year 2027. The Company is in the process of analyzing the impact of the ASU on related disclosures. There have been no material changes to the Company’s significant accounting policies set forth in "Note 1" of Notes to Consolidated Financial Statements included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2024.
