Security80Excellent
WordPress REST API user enumeration exposure
Your WordPress site exposes its user list through the REST API. Attackers can enumerate every account by username — the first half of any credential-stuffing attack is already done for them.
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.
Sensitive path exposure (.git, .env, /admin, xmlrpc.php, wp-login.php)
Some common admin or developer paths are reachable from the public internet.
SSL certificate validity & expiration window
Your SSL certificate is valid and not close to expiring.
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.
