TLS Version Checker

Instantly check which TLS protocol version your server negotiates and whether it meets modern security standards.

TLS 1.3 (2018) is the current gold standard — faster handshakes, no legacy cipher suites, forward secrecy by default. TLS 1.2 is acceptable when configured with modern ciphers.

TLS 1.0 and 1.1 are deprecated by all major browsers (since 2020) and standards bodies. They are vulnerable to BEAST, POODLE, and other attacks.
