Qualys Inc (NASDAQ: QLYS) is a cloud-based security and compliance software company that delivers vulnerability management, policy compliance, and related security solutions through a software-as-a-service platform. Revenue comes almost entirely from subscription fees paid by enterprises, government agencies, and managed service providers for access to the Qualys Cloud Platform. The 10-K filed 2026-02-20 (accession 000110784326000008) for the fiscal year ended confirms the subscription-based model, but the filing excerpts provided do not supply specific revenue figures, customer counts, segment breakdowns, geographic mix, named competitors, founding year, or current CEO tenure. Because the excerpts do not support those specifics, they are omitted here. The platform is delivered via the cloud, removing the need for customers to deploy on-premises hardware or software, which creates switching costs tied to data continuity, workflow integration, and compliance record-keeping built up over time on the platform.
