Many companies rely on Microsoft 365 on a daily basis – be it for emails, collaboration in Teams or document management in SharePoint. But only a few know how secure and optimally configured their environment really is. You can find out more about the security of an optimally configured environment in our blog: Microsoft 365 – How secure is working in the cloud really?

Risks often creep in over time: administrator rights that are too broad, unused licenses, insecure policies or missing compliance settings.

The result? Security gaps, inefficient use and avoidable costs.

The M365 Health Check from netxconsult – your security and efficiency update
Our M365 Health Check gives you a complete overview of the “health” of your tenant.
We check:
  • Security & compliance settings (including alignment with CIS best practices)
  • Admin and user rights (least privilege principle)
  • License usage and optimization
  • Configuration of Exchange, Teams, SharePoint & OneDrive
  • Guidelines for data backup and MFA
