Monitoring Certificate Expiration Date for a Website

Last modified on August 24, 2020

HTTPS websites use SSL certificates to secure connections between users’ browsers and the website. SSL certificates are time-limited. AlertSite can help you check your certificate expiration date and notify you up to 30 days before your certificate expires.

To monitor your certificate expiration date, configure a website monitor with the Report Expired SSL Certificates option:

AlertSite UXM

  1. If you do not have a URL monitor for your website yet, create one as explained in Creating a Single URL Monitor. Make sure to specify the URL beginning with https:// and not http://.

  2. Open the monitor settings and switch to the Advanced tab.

  3. Select the desired value for the Report Expired SSL Certificates option:

    • When Expired
    • 1 Day Before Expiration
    • 2 Days Before Expiration
    • 7 Days Before Expiration
    • 15 Days Before Expiration
    • 30 Days Before Expiration
    • 60 Days Before Expiration
    The Report Expired SSL Certificates option

AlertSite 1.0

  1. If you do not have a Secure Web Site monitor for your website yet, create one as explained in Creating a Single URL Monitor. Make sure to specify the URL beginning with https:// and not http://.

  2. Open the monitor settings. To do that, navigate to Configure > Sites and click your monitor on the list.

  3. Select the desired value for the Report Expired SSL Certificates option:

    • When Expired

    • 1 Day Before Expiration

    • 2 Days Before Expiration

    • 7 Days Before Expiration

    • 15 Days Before Expiration

    • 30 Days Before Expiration

  4. Click Submit in the top right corner.

Notes

  • PrivateNode Server locations handle the 60 Days option as 30 Days. That is, the alert from private locations will be sent 30 days (not 60 days) before the certificate expiration.

  • If you do not see the Report Expired SSL Certificates option, it means the monitor is not a URL monitor – for example, it is a real-browser monitor or API endpoint monitor. You need a URL monitor to check the certificate expiration date.

  • AlertSite sends the certificate expiration alert only once and sends no alerts when the certificate is updated.
