The Trust Gap: Let's Encrypt Notifications Have Ended
You might have noticed you haven't received any emails from Let's Encrypt for a while.
Starting on 4th June 2025, Let's Encrypt stopped providing free expiration email notifications. Don't let your certificates lapse and your trust score plummet.
No More Default Alerts
Millions rely on expiration emails. Without them, even major enterprises risk outages during DNS challenge renewals.
Centralized Visibility
Stop tracking expiration dates in spreadsheets. Get a single, authoritative dashboard for your entire domain estate.
Three Ways to Secure Your Perimeter
Enterprise-grade monitoring tailored to your workflow.
Built by Sysadmins,
for the Security-Conscious
We started Cert Monitor because we realised managing multiple certificates was about to become more difficult.
We've seen entire businesses taken offline for almost a full day, all because a single certificate expired.
We know the pressure of managing entire estates and the frustration of "surprise" expirations. Our mission is to make sure that never happens to you.
