Teams
Meeting, messaging, and external-access posture.

Frequently asked
Is the Microsoft 365 security check free?
You can explore a full check for free on our advanced simulation, and in the game, with no tenant access required. That is the best way to learn what a thorough check looks like and what Siemserva finds. To run the check against your own Microsoft 365 tenant you use a license key; 501(c)(3) nonprofits get the full version free.
How do I check my Microsoft 365 security settings?
Install Siemserva, run the advanced simulation to see how it works, then point it at your tenant with a key. It reads your configuration across Entra ID, Intune, Exchange, SharePoint, Teams, OneDrive, and Purview, ranks the findings by Severity, maps them to compliance controls, and gives you a validated remediation for each.
How is this different from Microsoft Secure Score?
Secure Score gives you a number. A Siemserva check gives you the specific misconfigurations behind it, ranked by Severity, each with the underlying evidence, the control it maps to, and a fix, across far more than Secure Score covers, with an AI interface on top.
Do I need to install an agent or connect to the cloud?
No agents and no cloud service. Siemserva runs on Windows or Mac and reads your tenant through Microsoft's APIs. The simulation needs nothing but the download.
