This feature is included for free in our Uptime Monitor service.

When adding an Uptime Monitor website that uses SSL, our system will automatically also monitor and display the SSL Expiration Date.

All SSL websites are monitored by default.

Once you add an HTTPS website to your Uptime Monitors list:

  • it can take up to 10 minutes for our system to initially discover your website’s SSL expiration date
  • it can take up to 60 minutes for our system to refresh your website’s SSL expiration date if/when it changes
  • email warnings go out once per day (if you choose to be alerted)

The SSL Certificate Expiration Date will be available in your Uptime Monitors list:

If your SSL Certificate is about to expire, a small warning sign will appear next to your Uptime Monitor in order to alert you about it:

*The small warning icon will also change colors depending on how many days are left until your SSL Certificate expires, varying from orange (less than 10 days) up to red (less than 5 days), so you can easily notice the ones which are going to expire soon.

You can also choose to get notified by our system, starting with X days before the expiration date.

These notifications are sent daily (one per day per uptime monitor), starting off X days before the expiration date (i.e.: if you select the 10 days option, you will receive one notification per day for the last 10 days before your certificate will expire).

*Please note that the notifications will be sent to the Uptime Monitor contact list, just as a regular Offline/Online status notification.

**If your Uptime Monitor has no contact list assigned to it, then there will be no SSL Expiration notifications sent, regardless of the setting you select above.

***The default setting for SSL Expiration notifications is disabled, so you will not receive such notifications from us, unless you configure this setting as described above.

Please note that this does not check the validity/authenticity of your SSL Certificate. This feature only monitors the expiration date.
