Free tools from Excession Labs: a security headers checker for any public site, and a pentest scoping checklist from PentestCompare.

Free tools you can use without an account.

## Security headers checker

[Security headers checker](/tools/security-headers-checker/) makes one request to a public site and grades its response headers: HTTPS, HSTS, CSP, framing, content type sniffing, referrer policy, permissions policy, version disclosure and cookie flags. Each result comes with the recommended value and copy-paste config for common stacks.
