Qualys Web Application Firewall (WAF) is a cloud-based security solution that blocks attacks and patches web application vulnerabilities. It operates as a virtual appliance deployable on VMware, Hyper-V, Docker, AWS, Azure, and Google Cloud Platform environments. The WAF continuously communicates with the Enterprise TruRisk Platform for configuration tracking and security event monitoring, while maintaining application traffic within the user's environment to minimize latency and maintain control. The solution integrates with Qualys Web Application Scanning (WAS) for vulnerability detection and provides centralized management through a single console. It scales to protect millions of assets and functions as a fully cloud-based platform designed to protect web applications from threats and attacks.
