SSL/TLS-Zertifikatsprüfung

A professional SSL/TLS check verifies the digital identity of your website and ensures that all data transmitted between the server and the browser is encrypted and secure. It checks the certificate validity, expiration date, and whether it is trusted by major browsers. More importantly, it inspects the "Chain of Trust" to ensure that intermediate certificates are correctly installed, preventing "Untrusted Connection" warnings on some devices. In addition to basic validity, our tool analyzes supported protocols (like TLS 1.2 and 1.3) and cipher suites to detect weak encryption that might be vulnerable to attacks. Since many websites use CDNs, a certificate might look valid in your region but be expired on an edge server in another country. A global SSL check ensures consistency across all edge nodes, protecting your brand reputation and user trust worldwide.
