FAQ
How often is the SSL leaderboard updated?
Watched domains are scanned daily; the top-20K leaderboard refreshes full snapshots every Sunday.
How is the SSL grade calculated?
Protocol versions, cipher strength, certificate validity, HSTS and OCSP stapling are weighted into a 0-100 score, mapped to grades from A+ to F.
What does an A+ SSL rating mean?
A near-perfect TLS setup: TLS 1.3 enabled, strong cipher suites, full forward secrecy (PFS) and correctly deployed HSTS.
Methodology
CertH grades each domain via pure TLS handshakes (no server access required): certificate validity, key strength, protocol versions, HSTS and OCSP stapling are scored with a deduction model (100 minus itemized penalties) into a 0-100 score mapped to six grades from A+ to F. Daily snapshots accumulate into an auditable health trend.
What is an SSL grade?
An SSL grade (A+ through F) evaluates a website's overall TLS configuration: protocol versions, cipher strength, certificate validity and trust chain, HSTS and OCSP stapling. A higher grade means stronger resistance to man-in-the-middle attacks and data breaches.
Why track certificate health over time?
Expired certificates, CA switches and configuration regressions can silently drag a grade down. CertH daily snapshots record those changes so you can spot risk before failures, with auditable history as evidence.
