What does CSP policy checker do?
It helps you inspect or process this value and get a readable result quickly.
Is my input saved?
Local tools run in the browser when possible. Server-side checks only use the input needed to complete the lookup.
How should I move from CSP report-only to enforced mode?
Start with `Content-Security-Policy-Report-Only` to collect breakage, then enforce incrementally. Prioritize script-src, object-src, frame-ancestors, and base-uri hardening first.
Why is unsafe-inline flagged as a major risk?
`unsafe-inline` broadens script execution paths and weakens XSS controls. Prefer nonce/hash-based script control with narrow source allowlists.
