Old and new portals merged

Since October 21, 2026, mijn.cemm.nl has been redirecting to portal.cemm.nl. This is the new portal for CEMM 3.0, which now also supports remote access to CEMM Basic and Plus. You can log in using the same account you have always used for mijn.cemm.nl.

This migration had been planned for some time, but we decided to accelerate the process due to the PHP vulnerabilities that came to light on October 21, 2026. The new portal does not use PHP and is therefore unaffected by these vulnerabilities.

The old Open API and Display services for CEMM Basic and Plus are currently still offline. We are working on a solution.

Are you still using a CEMM Basic or Plus? We are doing our best to keep all services available. However, we strongly recommend upgrading to CEMM 3.0 as soon as possible. This will ensure that your CEMM receives software and security updates again, while also giving you access to all the latest features and improvements.
