Your benefit – 
our added value

Take advantage of our expertise in the area of Microsoft 365 security: whether you need a sparring partner to discuss a new function or configuration or want to outsource the continuous hardening of the environment so that your team can concentrate on your core competence.


A well-designed Microsoft 365 environment ultimately addresses a large number of CIS best practice recommendations as well as regulatory requirements within NIS2 and DORA.

The Microsoft Secure Score is a security rating for Microsoft environments that helps companies analyze and improve their security situation. The numerical value shows how secure a Microsoft 365 environment is compared to best practices. 

Points are assigned for implemented security measures, e.g. the activation of multi-factor authentication, and compared with similar companies in the industry. This provides a good starting point for checking the current security configuration and analyzing requirements.
