QLYS Company Overview

Qualys, Inc. is a cybersecurity company that provides cloud-based security, compliance, and IT risk management solutions. The company operates within the cybersecurity, cloud security, and IT risk and compliance industries, delivering its services through a unified, subscription-based software-as-a-service (SaaS) platform. Qualys is best known for enabling organizations to continuously identify, assess, and remediate security vulnerabilities across IT infrastructure, cloud environments, and applications.

The company’s primary revenue drivers are recurring subscriptions to its security and compliance applications, including vulnerability management, cloud security posture management, endpoint detection, and compliance monitoring. Qualys serves a broad customer base ranging from small and mid-sized enterprises to large global corporations and government entities, with a strong emphasis on regulated industries such as financial services, healthcare, technology, and government. A key strategic advantage is its integrated cloud platform that allows customers to deploy multiple security functions without additional hardware. Qualys was founded in 1999 and transitioned early to a cloud delivery model, completing its initial public offering in 2012 and expanding its platform organically over time rather than through large-scale acquisitions.
