Audit HTTP Response Headers

HTTP response headers reveal more about your application than you might expect. Beyond security-specific headers, standard response headers can leak server software versions, internal hostnames, caching configurations, and application framework details. Some headers that should be present are missing, and some that should not be present are revealing sensitive information.

A comprehensive header audit examines every header in the response -- not just the security headers, but cache control directives that might expose sensitive data to shared caches, server identification headers that aid attacker reconnaissance, custom headers that leak internal architecture details, and CORS headers that might be too permissive.

This goes deeper than a simple security header check. It is a full analysis of what your application communicates through its HTTP responses. Organizations that handle sensitive data, operate in regulated industries, or have undergone security incidents need this level of detail to ensure their HTTP responses are not silently leaking information or creating attack opportunities.
