Overview
Qualys WAF was a cloud-managed web application firewall offered as part of the Qualys Cloud Platform. What made it unique was its deep integration with Qualys Web Application Scanning (WAS), allowing security teams to automatically generate WAF rules from discovered vulnerabilities — creating a seamless detect-and-protect workflow.
Important: Qualys announced the decommission of their WAF product effective September 1, 2024. This page is maintained for historical reference and for organizations that may still be transitioning away from the product.
The Qualys WAF deployed as a virtual appliance (VMware, Hyper-V, Docker, or cloud platforms) with centralized management through the Qualys Cloud Platform. Unlike cloud-proxy WAFs, application traffic stayed within the customer's environment, minimizing latency while the Qualys cloud handled configuration, updates, and reporting. The platform included pre-built policies for WordPress, Joomla, Drupal, SharePoint, and generic web applications.

Our Verdict
Qualys WAF was an innovative product that demonstrated the value of integrating vulnerability scanning with web application firewall protection. The ability to automatically generate WAF rules from scan results was ahead of its time and addressed a real pain point in application security workflows.
However, the product was decommissioned in September 2024, likely due to limited market traction in the highly competitive WAF space. Organizations still using Qualys WAF should plan their migration to an alternative solution.
Our verdict: An innovative but now-discontinued WAF that proved the concept of scan-to-protect workflows. Existing users should migrate to an active WAF product.
