# Uptime Monitor

{% hint style="info" %}
**Monitoring Tip:** SSL certificates are essential for maintaining the security of your website. An expired SSL certificate can lead to security warnings for visitors, potentially causing them to leave your site. MonSpark's SSL Monitoring feature automatically keeps track of your SSL certificates' expiry dates, sending alerts before they expire.
