# Enable SSL Uptime Monitor

Keeping your website secure is essential, and the security certificate (SSL) plays a crucial role in this. Worried that it might expire without you noticing? With Modular, we will alert you if your certificate is about to expire and avoid surprises.

If your plan includes SSL monitoring (Starter, Business and Enterprise), you can enable SSL expiration alerts in the [Uptime Monitor settings of your websites.](https://help.modulards.com/en/article/how-to-activate-and-setup-uptime-monitor-on-your-website-18u7f60/)

In addition, you will be able to choose how long before the expiration of the certificate you want to be notified. You can choose to receive alerts 30, 14, 3 or even 1 day before expiration. This way, you will have enough time to act and renew it without rushing.
