Checks the TLS protocol version and identifies outdated or insecure configurations.
This check verifies the TLS (Transport Layer Security) protocol version used by your server. TLS 1.0 and 1.1 are deprecated and contain known vulnerabilities. Modern sites should support TLS 1.2 (minimum) and ideally TLS 1.3 for optimal security and performance.
Outdated TLS versions (1.0, 1.1) have known security vulnerabilities that can be exploited to intercept encrypted traffic. All major browsers have dropped support for these versions. TLS 1.3 also offers performance benefits with faster handshakes.
Using deprecated TLS versions exposes your users to potential man-in-the-middle attacks. Major browsers may show security warnings, and PCI DSS compliance requires TLS 1.2 minimum for handling payment data.
