Scan your Microsoft 365 in minutes. Fix what is actually risky.
Senserva is an AI-enhanced security posture management and automated remediation product for Microsoft 365, Intune, Defender, Entra ID, and Purview. One small binary reads your tenant through Microsoft's APIs, read-only and least privilege: no agents, no cloud pipeline, and your data stays with you.
Free registration is all it takes, no card. Want it always on? Summer Special: unlimited use, up to 50 tenants, $600/mo or $6,500/yr.
What it replaces
Hardening Microsoft 365 the usual way means weeks of manual work: exporting from a dozen admin centers, hand-writing PowerShell, applying each fix by hand, and rebuilding audit evidence every cycle. Two reviews of the same tenant give different answers, and the backlog never clears.
Siemserva collapses all of it into one command. 650+ checks run in minutes, every finding arrives with a validated, ready-to-run fix, and audit-ready evidence is generated automatically: each finding pre-mapped to the Microsoft Cloud Security Benchmark and CISA SCuBA, and bridged through the MCP to NIST 800-53, 800-171, ISO 27001, SOC 2, and HIPAA. That is how teams cut up to 80% of the time they spend hardening Microsoft 365.
You will not be overwhelmed. The volume is Microsoft 365's: thousands of settings, identities, and log events exist whether or not anyone looks, and a real audit needs all of them. Siemserva's job is to hide that complexity. Findings arrive in priority order with plain-language descriptions, and drill-down is there when you want it.
It scales, too. One scanner runs a single tenant or every tenant an MSP manages, with bulk tenant audits and unified, client-ready reporting: Senserva for MSPs and MSSPs.
What a scan covers
A full Microsoft 365 security audit in one scan: 650+ checks, each mapped to the frameworks above, ranked by real risk, and paired with a validated fix. Run it once as a security posture assessment, or on a schedule as continuous assurance. The two largest areas alone, Entra ID and device management, carry 200+ and 190+ checks.
- Identity and access (Entra ID)
- A full identity risk assessment on every scan: MFA, Conditional Access, PIM, directory and Azure roles, authentication methods and strengths, FIDO2 and Windows Hello for Business, break-glass accounts, and risky users and sign-ins. 200+ Entra ID security checks.
- Privileged access
- Continuous privileged access monitoring and an Entra ID privileged access review on every scan: eligible versus active PIM assignments, role-management policies and alerts, plus Azure security auditing across subscription role definitions and RBAC assignments.
- Applications and service principals
- A Microsoft 365 permissions audit across app registrations, OAuth2 grants and scopes, credential hygiene, risky service principals, and app role assignments.
- Devices and endpoints (Intune)
- Compliance policies, configuration profiles, antivirus, firewall, attack surface reduction, BitLocker, app control, Windows security experience, and update rings. 190+ checks.
- Patch and CVE intelligence
- Per-device missing patches and CVEs enriched with MSRC, CISA KEV, and EPSS, ranked by the Senserva CVE Ranking so the fixes that matter rise first.
- Email security (Defender for Office)
- Anti-phishing, anti-malware, anti-spam, and Safe Links policies, checked against a secure baseline.
- Logging and threat detection
- Unified audit log health, sign-in and directory logs, provisioning logs, and security alerts, so the evidence is there when you need it.
- Purview and data governance
- Sensitivity labels, retention and records management, unified audit log, and subject rights requests for privacy and DSAR.
- M365 workloads and AI
- SharePoint, Exchange, Teams, and OneDrive configuration, plus Copilot and AI agent settings, so new surfaces get audited too.

Run it from Claude, or the AI of your choice
Siemserva ships a market-leading MCP, so Claude, or the AI you already use, can drive the whole product in plain language: scan, investigate, prioritize, and draft the fix, no KQL and no portals. Ask which problems in a tenant to fix first and the answer comes from the actual scan, with the evidence behind each finding. You can try it today without registering: the MCP demo mode runs against a built-in sample tenant, no tenant access and no key required.
For each finding, Siemserva generates a fix tuned to your tenant and validates it against your tenant's actual data. You review and apply it, often as ready-to-run PowerShell, from the Senserva UI or from Claude, and the next scan proves the gap is closed. Prefer a different model? Siemserva works with any AI, from ChatGPT and Gemini to a local model, using its built-in prompt builder and validation. How validated remediation works.
Every scan also becomes six reports, from a deep technical breakdown to a one-page executive summary, each carrying the evidence, the mapped control, and the validated fix. Self-contained HTML, print-ready for the audit binder. See the reports.
AI is on by choice and fully optional: the product is complete without it, and every AI suggestion is grounded in your real findings and validated before you act. Senserva Trustworthy AI.
Configuration, patching, and logs, in one model
Most posture tools stop at settings. Siemserva models your configuration, your patching and CVEs, and your logs as one connected model. Risk lives in the overlap: a weak setting on an unpatched device that is also being probed in your sign-in logs is far more dangerous than any one of those alone, and separate tools never see it. The single model is what ranks real risk, grounds the AI, and proves the gap is closed on the next scan. It also watches for configuration drift continuously, so what you fixed stays fixed.
A raw CVE list is noise. Siemserva reports the vulnerabilities and missing patches across your devices, enriches each one from the authoritative sources (MSRC, CISA KEV, EPSS), and ranks them by real-world risk, so you fix the handful that matter. Coverage runs the whole pipeline: per-device missing KBs and CVEs, Windows Autopatch and Windows Update for Business audits, third-party software via Defender Vulnerability Management, and a software inventory with per-product CVE counts. The full patch and CVE coverage.
Live from the Senserva CVE Ranking, from Mark Shavlik, creator of HFNetChk and MBSA (the Shavlik story). In your own tenant, Siemserva ranks the CVEs and missing patches on your devices the same way, with a validated fix attached to each. Patching is built into the same scan: Siemserva patching in action, and the free Microsoft patch tracker runs on the same engine.
Alongside the configuration checks, Siemserva investigates your sign-in logs as a 14-day replay, the unified audit log, directory and provisioning logs, and security alerts, so you see not just the door left unlocked but who walked through it. Risky activity is surfaced, ranked, and tied to a fix, next to the misconfigurations that let it happen. Full Microsoft 365 log analysis | Conditional Access gap analysis.
What one model is worth
The value lands in two places: the hours it gives back every month, and the gap it closes that nothing else did. Both came from users, not from us.
