WhatWaf – Detect and bypass web application firewalls

Web application firewalls is an important part to secure your web application. The WAF consist of several filters and rule engine that will analyze and block malicious requests in real-time before they arrive to the web server. This is a good protection but they may include vulnerabilities that allow attacker to detect and bypass them. If you are looking to test a web application firewall you can check WhatWaf.

WhatWaf is an advanced firewall detection tool whose goal is to give you the idea of “There’s a WAF?”. WhatWaf works by detecting a firewall on a web application and attempting to detect a bypass (or two) for said firewall, on the specified target.
