LetsMonitor.org is a free service to enable website certificate owners to receive alerts when their certificates are close to expiring or misconfigured. The service will send notifications to multiple contacts.

New Feature:

HTTPS uptime and performance can now be monitored to ensure your sites are encrypted and responsive.

Encryption on the web is rapidly increasing thanks to the release of Let's Encrypt. Certificates are being issued with shorter timeframes, so they require regular renewals. We provide an extra level of monitoring to help you make sure your certificates do not expire and are operational on all major browsers.

LetsMonitor.org uses globally distributed servers to monitor your certificates to ensure worldwide access to your secure site.

Get alerts via  email or  SMS.

Additional services
In addition to certificate monitoring, LetsMonitor.org has other advanced monitors:

Performance and availability monitors
