Description
The SSL Monitor add-on automatically checks the SSL certificate status of all WordPress sites managed by MainWP, adding an SSL status column to the “Manage Sites” screen and keeping a history of checks accessible through the extension panel. With configurable check frequency per site and early email alerts, the component eliminates the manual routine of opening each domain to confirm that HTTPS is still valid.

Benefits of the SSL Monitor Extension
- No more manual routines
Eliminates the need to open each site to check certificate validity. - Prevents HTTPS downtime

Who Is It For?
- Agencies and professionals managing multiple WordPress sites through MainWP.
- Maintenance teams responsible for uptime and security contracts.
- WordPress freelancers who provide monitoring services and ongoing care.
For those operating maintenance portfolios with dozens or hundreds of sites in the MainWP panel, the extension closes a common blind spot: SSL certificates that expire without warning and generate customer tickets. By centralizing checks, early alerts, and the history of checks in the same management interface, the module turns HTTPS monitoring into an automated and auditable routine.
