This package identifies and fingerprints Web Application Firewall (WAF) products using the following logic:

  • 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.
