SSL certificate & TLS checker
Inspect certificate trust, expiry, server protocols and HTTPS configuration. See the evidence, your score and what to fix.
What does this SSL test check?
It connects directly to public HTTPS endpoints, reads the presented certificate chain and tests protocol negotiation. Expand each result to see the evidence and repair advice. A 100/100 checklist score covers only the listed checks.

How the score works
Our checklist v2 has nine criteria worth 100 points. Failed criteria lose their stated points; unknown results show a range. Certificate criteria use the worst observed endpoint. This is not an SSL Labs grade or a security certificate.
Up to four public IPs, with IPv4 and IPv6 prioritized. Protocol checks use one selected IP. No full cipher or vulnerability audit; revocation and all browser trust stores are not checked.
Only the hostname is tested; URL paths and query parameters are discarded. Reports expire after one hour. Anyone with the report link can view it. Limit: ten checks per hour.
