SSL Checker
Use this checklist to validate certificate trust, coverage, and configuration before review or incident response.
Certificate review checklist
These checks apply to production hosts, API gateways, and internal services with external access.
Issuer trust
Confirm the certificate chains to a trusted root and is not self-signed in production.
Validity window
Review notBefore/notAfter. Renew before expiry and watch for long-lived certificates.
Hostname match
The certificate subject or SAN must match the public hostname users visit.
TLS version and cipher
Prefer TLS 1.2+ and modern cipher suites; disable legacy protocol versions.
OCSP and stapling
Check revocation behavior and stapling when available to reduce latency and trust checks.
