TLS Check inspects which TLS/SSL protocol versions a server supports. It probes TLS 1.0 through 1.3, reports which are negotiable, and derives a security verdict — the highest supported version, whether deprecated protocols are still exposed, and a composite risk score.

The TLS Checker API provides a simple, reliable way to integrate tls checker functionality into your applications. Built for developers who need production-ready tls checker capabilities without the complexity of building from scratch.
