Its offerings include vulnerability management and detection and response, cloud security, asset management, and compliance capabilities.[1]+2 The company describes its mission as helping customers “De-risk your business” by measuring, communicating, and eliminating cyber risk.[4]

Founded in 1999, Qualys serves customers across the Americas, Europe, the Middle East and Africa, and Asia-Pacific; its website reports more than 10,000 subscription customers in 130 countries.[5]+2 It reported 2,625 employees worldwide at year-end 2025 and FY2025 revenue of $669.1 million.[6][8] [1]+9

Products & services

Qualys offers a portfolio of more than 20 cloud applications through its unified, multi-tenant platform, with open APIs and integration tools. Subscriptions generally cover a specified number of devices or web applications and include unlimited scans; customers may also deploy physical or virtual scanner appliances. The company also supports private-cloud deployments, including on-premises and virtualized environments.[9]+2

Key products include Cybersecurity Asset Management (CSAM), which discovers and inventories assets and adds business context and attack-surface insights; Enterprise TruRisk Management (ETM), which combines Qualys and third-party risk signals to prioritize risk and support remediation workflows; and Vulnerability Management, Detection and Response (VMDR), which discovers assets, assesses and prioritizes vulnerabilities, identifies patches, and tracks remediation across on-premises, endpoint, cloud, container, and mobile environments. Total Application Security discovers and tests web applications and APIs, supports DevOps integrations, and detects website malware.[11]+3

Other offerings include Patch Management and TruRisk Eliminate for automated patching and remediation; Custom Assessment and Remediation for user-created assessments and response automation; and endpoint detection and response combining endpoint telemetry with asset, vulnerability, exploit, and network context. Policy Audit automates configuration and compliance assessment, while File Integrity Monitoring tracks file changes. TotalCloud provides multi-cloud security and compliance capabilities, including cloud workload protection, threat detection, posture management, identity entitlement management, and Kubernetes and container security.[14]+7

Free offerings include Global AssetView for real-time asset inventory and Certificate Inventory for assessing internet-facing SSL/TLS certificates and tracking expiration. Qualys also provides customer support and product training. The reviewed filings do not report revenue percentages by product or product family; they identify one operating and reportable segment.[22]+6 [9]+23

Geographic presence

Qualys generated 56% of its 2025 revenue from U.S. customers, based on customer billing address, compared with 58% in 2024 and 60% in 2023. Its sales teams are organized across the Americas, Europe, Middle East and Africa, and Asia-Pacific. In the six months ended June 30, 2026, customers outside the U.S. accounted for 62% of the year-over-year revenue increase; this is a share of growth, not of total revenue.[29]+2

As of December 31, 2025, Qualys had 2,625 full-time employees; approximately 78% were outside the U.S., including 70% in India. Its disclosed office locations include Foster City, California; North Carolina; Pune, India; France; the UAE; and the UK.[31][32] Qualys also operates cloud platforms at third-party facilities in the U.S., Canada, Switzerland, the Netherlands, the UAE, Australia, the UK, Italy, Saudi Arabia, and India; these are hosting locations, not necessarily offices.[33] [29]+5

Business segments

Qualys reports one operating and reportable segment, with no separately named business segments. Its chief operating decision maker evaluates performance and allocates resources on a consolidated basis; accordingly, the sole segment represents 100% of reported company revenue, rather than a separately disclosed portion of it.[34][26]

The segment’s focus is the Qualys cloud platform for IT, security and compliance, including asset discovery and management, security and compliance assessments, vulnerability and cyber-risk prioritization, remediation, and verification across IT/OT, applications, endpoints and cloud environments.[1]

Qualys also discloses revenue through other lenses, which are not operating segments: by customer billing address, the U.S. contributed approximately 56% of FY2025 revenue and other countries approximately 44%; by sales channel, approximately 51% was direct and 49% through partners.[29][35] [34]+4

Company history

Qualys was founded in 1999. In December 2000, it announced an online security platform featuring network mapping and vulnerability scanning. Philippe Courtot, who had invested in the company, became CEO in March 2001.[36][37]

The company expanded its technology and research through acquisitions, including Nemean Networks in 2010, which added intrusion- and malware-detection research. In 2012, Qualys expanded its cloud platform with offerings such as a Web Application Firewall and virtual scanner appliances, and completed its initial public offering, pricing shares at $12.[38]+2

In 2015, Qualys introduced its Cloud Agent Platform for continuous asset inventory and assessment. It acquired Layered Insight in 2018, adding container security capabilities, and software assets from Adya in 2019 to extend into SaaS application management. Sumedh Thakar became president and CEO in April 2021, following Courtot’s departure for health reasons.[41]+3
