Microsoft 365 security questions, answered

You can explore a full Microsoft 365 security check for free on our advanced simulation, and in the game, with no tenant access needed. Scanning your own tenant uses a license key, and 501(c)(3) nonprofits get the full version free. Ask about Microsoft MVP and MSP pricing.

Install Siemserva, run the free 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 findings by Severity, maps them to compliance controls, and gives a validated remediation for each.

Try the security simulator

No. Siemserva runs on Windows or Mac and reads your tenant through Microsoft's APIs. No agents, no cloud service, your data stays with you.

How Siemserva runs, secure and private

650+ checks across the Microsoft 365 stack: Entra ID identity (MFA, Conditional Access, PIM, risky users, FIDO2, app credentials), Intune device management, Exchange and email protection, SharePoint, OneDrive, Teams, Purview data governance, Azure RBAC, and Copilot / AI agent configuration.

See the full depth of coverage

Siemserva works with whatever you have licensed. At scan time it reads your subscribed SKUs and service plans from Microsoft Graph and automatically runs the checks your licensing supports, so coverage deepens as you add Microsoft Entra ID P1 and P2, Intune, Purview, and Defender. If a workload is not licensed or the scanning account cannot reach it, those checks are reported as skipped rather than failing the scan, so you always see what was and was not covered. For a full feature-to-license map, which license unlocks Conditional Access, PIM, DLP, and the rest, plus how to buy each SKU and roughly what it costs, see the Microsoft security licensing guide.

Security posture management is the ongoing practice of measuring how your environment is actually configured against security best practice and compliance baselines, then closing the gaps. Siemserva does this continuously for Microsoft 365, ranking risks and helping you remediate them.

The Microsoft security landscape

Secure Score gives you a single number and high-level tips. Siemserva gives you the specific misconfigurations behind your posture, ranked by Severity, each with the underlying evidence, the control it maps to, and a fix, across far more than Secure Score covers. It is the fastest path to real Microsoft Secure Score improvement.

Siemserva and Microsoft Secure Score

Run Siemserva against your tenant for a full Entra ID security audit: it surfaces standing vs. eligible privileged roles, Conditional Access gaps and bypasses, break-glass hygiene, risky users and sign-ins, FIDO2 coverage, and risky applications and OAuth grants, each mapped to a control with a remediation step.

Entra ID security audit, in depth

Siemserva does not just report. Its agentic remediation turns findings into reviewed fixes (for example PowerShell) you can ship with confidence, and the evidence updates on the next scan.

How AI remediation works

Microsoft Cloud Security Benchmark (MCSB) v2 and CISA SCuBA are mapped natively in every report. It also covers Microsoft Zero Trust Assessment, Secure Score, EIDSCA, and Purview, and bridges to NIST 800-53, ISO 27001, SOC 2, HIPAA, PCI-DSS, CIS Controls, and MITRE ATT&CK through the Claude MCP layer. CMMC, NIST 800-171, and GCC support are targeted for Q3 2026.

Compliance and frameworks

Yes. Siemserva maps findings to CISA SCuBA baselines natively, so you can assess, prove, and remediate SCuBA posture across Microsoft 365 in one place.

SCuBA and MCSB compliance

Siemserva ships an MCP server so you can run the entire product from Claude. Ask, in plain language, which controls you fail or which Conditional Access gaps exist, and Claude answers from your real scan data and helps you remediate. You can use the full Senserva UI or the full Claude MCP interface over the same data, your choice.

Claude and the Senserva MCP

Senserva Trustworthy AI is built with guardrails so answers are grounded in your actual scan data, not guesses. The AI reasons over real findings and cites the evidence behind its recommendations.

AI-enhanced security reports

Yes. Siemserva is a multi-tenant Microsoft 365 security tool for managed service providers. Run MSP M365 security scanning and bulk tenant security audits across many customers, with unified, client-ready reporting. See how MSPs save time with Siemserva.
