HTTP security header review
Turn a response snapshot into a contextual browser-policy review, with evidence and the next checks to make.
Purpose, output & limits Evidence-backed response review
Before changing browser policies on an application.
Evidence-backed response review
Does not scan a site or validate an entire CSP.
Processed in this page’s memory. No tool-input uploads, target requests or persistent input storage. Clear or reload to discard this draft. Downloads are saved only when you request them. Keep secrets and confidential records out.
Start with one response.
Copy response headers from browser developer tools. Unsupported header values are removed; supported policy values remain. Remove credentials and sensitive URLs first.
How to obtain the right evidence
In browser developer tools, open Network, select a document or API response and copy the response-header lines. Record which response and environment you selected. A request header or a URL is not the same evidence.
A deliberate review.
A usable document.
Paste a response snapshot, set its context and run the review. No target will be contacted.
- Recognized evidence, not a score
- Interpretation with explicit limits
- Next checks and an exportable report
