Web Application Firewall detected

Description
  • This server is protected by an IPS (Intrusion Prevention System), IDS (Intrusion Detection System) or an WAF (Web Application Firewall). Acunetix detected this by sending various malicious payloads and detecting changes in the response code, headers and body.
Remediation
  • If possible, it's recommended to scan an internal (development) version of the web application where the WAF is not active.
