Compare the Top Web Application Firewalls (WAF) as of October 2025

What are Web Application Firewalls (WAF)?

Web Application Firewalls (WAFs) are security solutions that protect web applications by filtering and monitoring HTTP traffic between the application and the internet. They detect and block threats such as SQL injections, cross-site scripting (XSS), and other common attacks targeting application vulnerabilities. WAFs analyze incoming requests in real time, applying customizable security rules to distinguish between legitimate and potentially malicious traffic. Many WAFs are cloud-based, enabling flexible and scalable protection without impacting application performance. By acting as a shield between web applications and attackers, WAFs help ensure data security, regulatory compliance, and uninterrupted user access.
