Security63Solid
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 site isn't sending any of the standard browser-protection headers.
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.
Certificate key strength and signature algorithm
Your certificate uses outdated key strength or a SHA-1 signature. Reissue with a modern ACME-class cert.
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.
Your TLS handshake is on the slower side. A CDN with anycast edges and session resumption usually cuts this in half.
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.
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.).

Email health66Excellent

DMARC aggregate reporting enabled (rua=)
No DMARC aggregate-reporting address is published — you wouldn't see spoofing attempts.
Lead magnet / signup incentive detected (free download, ebook, etc.)
