TLS/SSL Certificate Monitoring

Monitor the validity of your TLS/SSL certificate and get alerted when there is a problem. Avoid embarrassing security warnings because you were alerted well in advance and renewed the certificate on time.

TLS/SSL Certificate monitoring in Semonto

Keep your certificates valid

An SSL/TLS certificate (also called HTTPS certificate) proves that the connection between your web server and your web browser is secured by the required encryption over the HTTPS protocol. But just like any certificate, an TLS/SSL certificate has an expiration date. TLS/SSL certificate monitoring helps you remember these important renewal dates. Semonto warns you well in advance when your certificates are about to expire so that you can get your certificates renewed before it becomes a problem.

Semonto informed us that our SSL certificate was about to expire. This was unexpected because we have automatic renewal via Let's Encrypt. Since we force the use of https, our site was guaranteed to go offline. Semonto gave us a warning in advance, and a certain crisis was prevented!

Why you need TLS/SSL certificate monitoring

To avoid security warnings

If you forget to renew your SSL certificate, your website or webshop will be flagged. Visitors will get a message that 'the connection is not private' or 'this website is not secure'. Not exactly a good first impression. By renewing your certificate in time, you make sure that your visitors are never scared away by these alarming messages.

To double-check automatic renewal scripts

We send you a reminder when your SSL certificates are about to expire. Because even if you have enabled automatic renewal scripts, something can still go wrong. Don't wait until your SSL certificate has expired. Use Semonto to stay ahead of problems.

To check against the certificate revocation list

Even if your certificate expiry date has not yet been reached, your SSL Certificate can be revoked remotely for other reasons. The Online Certificate Status Protocol (OCSP) keeps track of all certificates that were revoked. Semonto double-checks with the OCSP to make sure that your certificate has not been revoked and that your SSL Chain is valid at all times.

Prevent your (web)apps from being broken

Apps quite often use an API where the communication also is over https to protect the users privacy and security. If the certificate expires the users privacy and security might be compromised or the app could fail to work. Make sure to monitor those too.

Get notified of any SSL issue

The expiry date is not the only thing to keep an eye on. There is a validation chain that runs all the way from the root certificate to your domain certificate. Any error or expired element in that chain can cause your SSL certificate to fail. Your certificate can also be revoked, even if your expiry date has not been reached. Semonto takes all these factors into account and lets you know when action is required.

Get started in minutes

Get started

TLS/SSL certificate monitoring is available on all our plans. Each website or server that you start to monitor will have validation of the certificate enabled by default.

Get notified

We will send you notifications how you prefer, via email, SMS, push notifications and more. You will be notified before one of your SSL certificates has expired so you can react in time. The first alert will be 14 days before it expires and if you haven’t renewed the certificate you will receive another alert 5 days before it expires.

Get confident

You do not need to remember expiration dates anymore. No need to wake up in the middle of the night wondering whether you renewed your certificate in time. Semonto will let you know.

Easy management

Semonto provides you with an overview of all the TLS/SSL certificates you monitor so you can quickly see which certificates are about to expire or have other configuration issues.

Tests from multiple locations

Semonto performs the same tests from multiple locations to avoid false positives. In other words, we get a ‘second opinion’ before alerting you. If your server is down in one location (for example, Amsterdam) we verify the result by testing again from a second location (for example, New York). Only if both test locations confirm the problem, we send out an alert. If you want, you can go even further and specify how long we should wait before notifying you for each test.

Our testing locations:

  • Amsterdam (The Netherlands)
  • Frankfurt (Germany)
  • New York (USA)
  • San Francisco (USA)
  • Bangalore (India)
