Security80Excellent
There's no CAA record at your registrar saying which companies are allowed to issue certificates for you.
Your server doesn't staple OCSP. Visitors' browsers may have to contact the CA themselves, slowing first connects.
Neither OCSP stapling nor Must-Staple is in play. A revoked cert wouldn't be caught quickly.
Embedded SCT count (Certificate Transparency)
Your certificate carries only one embedded SCT — modern browsers want at least two. Reissue from a CA that includes them.
SSL certificate validity & expiration window
Your SSL certificate is valid and not close to expiring.
Sensitive path exposure (.git, .env, /admin, xmlrpc.php, wp-login.php)
None of the common admin or developer paths are publicly reachable.
Only modern TLS (1.2 and above) is offered — TLS 1.0 and 1.1 are turned off.
Modern cipher suite preference
The handshake negotiates a modern AEAD cipher (AES-GCM or ChaCha20-Poly1305).
Forward secrecy is guaranteed by the negotiated handshake — past traffic stays unreadable even if your key leaks.
Certificate key strength and signature algorithm
Your certificate uses strong modern math (ECDSA P-256+ or RSA-2048+ with SHA-256+).
Certificate chain completeness
Your server sends the full certificate chain — every device builds the path to a trusted root cleanly.
Certificate validity-period brevity
Your certificate uses a short validity window (≤ 90 days) — auto-renewal keeps revocation fast and frictionless.
Your certificate is issued by a tier-1 publicly trusted CA (Let's Encrypt, DigiCert, Google Trust, Sectigo, etc.).
Your TLS handshake completes quickly — under 300ms on a cold connection.
