Frequently Asked Questions

The tool tracks cipher suites, TLS extensions (SNI, ALPN, OCSP stapling), protocol versions, key exchange methods, and other TLS capabilities supported by the server.

Some extensions like SNI and ALPN improve functionality, while others like OCSP stapling enhance performance. Certain extensions may also have security implications depending on how they are configured.

Enable modern features like TLS 1.3, ALPN, and OCSP stapling. Disable legacy features like SSLv3, RC4, and weak ciphers. The tool helps you identify which features are currently enabled and their security status.
