Use Security Headers Checker
- You need to review response headers like CSP, HSTS, frame, content-type, and referrer policy.
- A launch checklist requires browser-facing header signals.
- You want to compare with redirect and status behavior.
Tool comparison
Security Headers Checker vs SSL Checker
Security headers and SSL certificates are different public-site signals. Use both for website launch triage, but do not treat either report as full security assurance.
Decision
Which one fits the task?
Use SSL Checker
- You need certificate issuer, expiration, host, or TLS-related public certificate signals.
- A browser or monitor reports certificate problems.
- You want to confirm the site presents a certificate for the expected host.
Avoid
Common mistake
These tools do not perform penetration testing, vulnerability scanning, or security certification.
Quality
Review before you finish
Quality notes
- Header results can differ by path, redirect, and CDN behavior.
- SSL results can change after certificate rotation.
- Use DNS, redirect, and status tools for the full public-site triage path.
Next steps
- Check redirects and status first if the URL does not resolve cleanly.
- Run both header and SSL checks before launch.
- Document findings as triage signals, not final security approval.
