SSL Certificate Test
Verifies the validity and configuration of the SSL certificate.
What is this check?
This check ensures your site's SSL/TLS certificate is correctly installed, valid, and trusted. A full check validates the certificate chain, expiration date, hostname match, and signature algorithm.
Why is it important?
A valid SSL certificate is the foundation of a secure website (HTTPS). It encrypts data between the user's browser and your server, protects against eavesdropping, and verifies your site's identity.
What is the impact?
An invalid, expired, or untrusted certificate will cause browsers to show prominent security warnings, scaring users away and destroying trust. It's a critical security and usability issue.
