TLS Protocol Scanner

Detect which TLS versions (1.0, 1.1, 1.2, 1.3) an FTP/FTPS server supports. Identify outdated or insecure TLS configurations.

TLS versions — which ones are safe?

TLS 1.0

Deprecated. Vulnerable to POODLE and BEAST attacks. Should be disabled.

TLS 1.1

Deprecated. Removed from modern browsers and clients. Should be disabled.

TLS 1.2

Widely supported and considered secure when configured with strong cipher suites.

TLS 1.3

The latest standard. Faster handshake, stronger security, forward secrecy by default. Recommended.
