SSL Checker

Check SSL/TLS certificate, chain and expiry date

What does SSL Checker verify?

Our SSL Checker verifies the TLS/SSL certificate of your domain: validity, expiry date, CA chain, supported protocols and cipher suites. Grade A+ means a correctly configured certificate with a modern protocol.

Grade scale

A+ — TLS 1.3, over 60 days validity. A — TLS 1.2+, over 30 days. B/C — valid but expiring soon. F — expired certificate.
