Header Guardian

Summary: Header Guardian is a Burp Suite extension, authored by OlderMutt and listed at version 1.0, that identifies missing, misconfigured, and unnecessary HTTP security headers in web applications. The listing states that properly configured security headers are critical in protecting against vulnerabilities such as cross-site scripting, clickjacking, and information leakage, and notes the extension was last updated on 30 October 2024.

What you should know: The tool exists because missing or misconfigured security headers leave applications exposed to XSS, clickjacking, and information leakage - and PortSwigger states it makes no warranty about the quality or usefulness of third-party extensions like this one for any particular purpose.
