How to monitor your TLS/SSL certificates

TLS/SSL monitoring allows you to keep an eye on multiple websites and their security certificates. This way, you can renew your SSL certificates in time and fix problems before your visitors are affected.

What is a TLS/SSL certificate?

Through the HTTPS protocol, your website uses a TLS/SSL certificate to prove that the connection between your web server and your web browser is secured by the required encryption.

Why monitor your TLS/SSL certificates?

Just like any certificate, an SSL certificate has an expiration date. HTTPS Monitoring helps you remember these important renewal dates. Semonto warns you well in advance when your TLS/SSL certificate is about to expire so that you can get your certificate renewed before it becomes a problem.

What TLS/SSL certificate monitoring tells you:

  • If you forget to renew your certificate.
  • If your automatic renewal didn’t go through.
  • Whether the correct certificate was used.
  • If something is wrong with the security chain (and what).
  • If the expiry date is approaching.
