TLS Cipher Suite Checker

TLS Cipher Suite Checker connects to a server on port 443 and reports the TLS protocol version and specific cipher suite it actually negotiates, then judges whether that combination is considered modern and strong.

Use this when a security scan or compliance checklist asks about cipher strength, or when investigating whether an old server is still offering outdated protocol versions like TLS 1.0 or 1.1 that modern browsers are phasing out.

A server can support several protocol versions and cipher suites at once and simply picks its preferred one during a normal handshake, so this shows what is actually negotiated by default, not the full list of everything the server is technically capable of.
