WAFW00F
WAFW00F allows one to identify and fingerprint Web App Firewall
The Web Application Firewall Fingerprinting Tool. Sends a normal HTTP request and analyses the response; this identifies a number of WAF solutions. If that is not successful, it sends a number of (potentially malicious) HTTP requests and uses simple logic to deduce which WAF it is. If that is also not successful, it analyses the responses previously returned and uses another simple algorithm to guess if a WAF or security solution is actively responding to our attacks. -
