up to 80%

less time spent on Microsoft 365 security

Hardening Microsoft 365 the usual way means weeks of manual work: exporting from a dozen admin centers, hand-writing PowerShell, chasing every fix, and rebuilding audit evidence each cycle.

Senserva 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, so your existing team covers far more without adding people.

That is how teams cut up to 80% of the time they spend hardening Microsoft 365.

Run it from our UI, from Claude through the Senserva MCP, or with any AI you already use: Siemserva builds the prompt, validates the answer, and writes the report. Every AI output is grounded in your real findings and validated before you act: Senserva Trustworthy AI.

Compliance, configuration, patching, and logs in one model: the state of the art for Microsoft 365 security, and what lets AI reason across your whole estate, MSPs included. From Microsoft MISA partner Senserva.

"Senserva cut my tenant hardening effort by 80%. Setup takes minutes, results are immediate. The AI doesn't just report findings, it reasons about your environment and tells you exactly how to fix them. If you work with Microsoft 365, Intune, or Entra ID, this is the tool you didn't know you were missing." Timo Becirovic, Municipal IT Consulting, ITEBO GmbH

"Senserva exists because good organizations, small and large, were failing audits with tools that weren't built for them. We built one solution that fits a small IT team and works alongside a Fortune 500 security program. For smaller firms it can be the whole solution; for larger firms, part of it. Same core tech, all Microsoft." Mark Shavlik, Founder & CEO. Microsoft NT Kernel team. Founder of Shavlik Technologies (HfNetChk, MBSA).

"Canadian organizations need security assessments they can put in front of an auditor with confidence - and for those operating under Federal data privacy and sovereignty requirements, the bar is higher still. Siemserva gives our clients a clear picture of their Microsoft 365, Entra ID, and Intune posture, maps every finding to compliance frameworks, and delivers audit-ready output built on Senserva Trustworthy AI. That combination of assessment depth and provable remediation is exactly why we brought Senserva into our portfolio." Siti Mwakatobe, Director of Sales / Directeur des Ventes, NET-WALL Internet Security, Inc.

"I gave Siemserva a test run and the core of the tool is genuinely impressive. Deep Microsoft 365 security findings, with a clear path from 'here's the gap' to 'here's how we fix it.' For MSPs especially, it's the kind of engine that can turn a complicated tenant review into actionable next steps." Simon Ronald, Cybersecurity & IT Director, Brave North Technology

"We believe Senserva provides a great amount of innovation in the Microsoft security world... The Senserva team was great to work with, responsive and focused on meeting our needs." Rich Lilly, Partner, Director of Security, Netrix

"The Senserva team is great to work with, they are responsive and could find any data in Azure we needed. It's amazing really." John McCann, CEO Satisent, A Gamma Company

"... The Siemserva team have moved incredibly fast to deliver a compelling approach to Microsoft 365 modern workplace risk visibility. They're surfacing blind spots other tools miss, and their AI-first reporting gives the platform a true voice, helping organizations understand not just what's at risk, but what to do about it." Nick Johnson, Program Manager IT Solutions, Loffler

AI-enhanced reports your auditors actually read

Every scan 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. The AI provides new and powerful insights; the evidence makes them defensible. Self-contained HTML, print-ready for the audit binder.

See the reports

CVEs and missing patches, ranked by what can actually hurt you

A raw CVE list is noise. Siemserva reports the vulnerabilities and missing patches across your estate, 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, not the thousands that do not. 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.

Shavlik patch management heritage runs deep here. Siemserva is founded by Mark Shavlik, the creator of the Shavlik patching products HfNetChk, MBSA, SCUPdates, and more, the patch tools a generation of Windows admins relied on. Now that Siemserva tracks patch and CVE data too, it is the modern Shavlik patch state tracker from the same people. The Shavlik story.

Validated AI remediation, not just findings

For each finding, Siemserva generates a fix tuned to your tenant and validates it. You review and apply it, often as ready-to-run PowerShell, from the Senserva UI or from Claude through the Senserva MCP. The next scan proves it worked. 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

Siemserva validated AI remediation in Claude

Misconfigurations are half the story. Your logs are the other half.

Most posture tools stop at settings. Siemserva reads your logs too. Alongside 650+ configuration checks, it investigates your sign-in logs, 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 surfaced, ranked, and tied to a fix.

Configuration tells you where you are exposed, patching tells you what is unfixed, and logs tell you whether it is being used against you. Bringing configuration, patching, and logs together in one model is the state of the art for security, and it is what lets the AI reason across your whole estate to create better, grounded solutions. Siemserva does it all, in one scan.

Catch configuration drift, continuously

A tenant that was secure last quarter quietly is not this quarter. Settings change, exceptions linger, and Microsoft moves defaults. Siemserva compares your live configuration against a known-good baseline on every scan and surfaces exactly what has drifted, so you can run it on a schedule and keep your modern workplace on baseline between audits. That continuous security drift management keeps misconfigurations from quietly piling up between reviews.

Baseline comparison
Every scan is measured against a secure baseline mapped to MCSB and CISA SCuBA, so drift is defined against a standard, not a guess.
Identity and role drift
Catches Conditional Access exclusions that linger, MFA quietly disabled, and Azure or Entra role assignments that drift from approved access.
Intune and device drift
Flags compliance policies, configuration profiles, and update rings that have slipped, per device and per tenant.
Run it on a schedule
With continuous scanning, drift is caught as it happens, not at the next audit, with a validated fix attached to each finding.

One scanner, from a single tenant to an MSP fleet

Siemserva by Senserva scans your Microsoft 365, Intune, Defender, Entra ID (logs included), CVEs, and Purview tenant, surfaces what matters, and helps you remediate it, whether you run a single tenant, multi-tenant, or MSP fleet. That means Intune compliance auditing, Entra configuration auditing, and continuous tenant monitoring in one Entra ID security scanner. See how it stacks up against other Microsoft 365 audit tools, including native and dedicated Intune audit tools. MSPs cut security management time across every client tenant, standardized and run from one place. Works Great for MSPs, saving time and helping you solve all the difficult problems. It is built on three decades of Microsoft security heritage from founder Mark Shavlik.

"Senserva cut my tenant hardening effort by 80%. Setup takes minutes, results are immediate. The AI doesn't just report findings, it reasons about your environment and tells you exactly how to fix them. If you work with Microsoft 365, Intune, or Entra ID, this is the tool you didn't know you were missing."

Purpose-Built for Microsoft 365 Security

Get more from the Microsoft security tools you already own. Siemserva surfaces what matters across every domain. One scan, one view, one tool. Combine our 650+ checks with Microsoft Zero Trust Assessment and Maester, both plug in as first-class integrations. Your own PowerShell scripts drop in with zero code changes: emit a Senserva JSON file and they land in the same graph, no SDK required. Want deeper access? The Senserva SDK exposes the full graph in C#, Python, and PowerShell. Every source, native or external, maps to the same compliance controls, dashboard, and AI reports.

A real application, not a pile of scripts

Siemserva is compiled, native software written in C# and .NET, not a bundle of PowerShell. That is where the depth comes from: a security graph, Microsoft Graph delta queries, an in-memory model, and native-code speed in one small binary. It can generate PowerShell remediation for you, but the engine is real software, well beyond what a script can do.

Frequently asked

Does Siemserva install agents or use a cloud service?

No. It runs on Windows or Mac and reads your tenant through Microsoft's APIs, read-only and least privilege. No agents, no cloud pipeline, and your data stays with you.

How long does setup take?

About 20 minutes from download to your first findings. You can explore the whole product first, free, on the Advanced Microsoft 365 Security Simulator or the game, with no access to your tenant. See the quick start.

How many checks are there, and can I see the list?

650+ checks across Microsoft 365, Intune, Defender, Entra ID, and Purview, in one scan. You can browse the full searchable checks catalog: each shows what it checks and the risk if you do not.

What does Siemserva check for Conditional Access?

It runs the most powerful Conditional Access evaluator we know of: every policy against every user, app, and condition, finding users no policy covers, risky exclusions, legacy authentication, and report-only policies that were never enforced. See Conditional Access gap analysis.

Does it analyze logs, not just configuration?

Yes. Alongside configuration checks it reads your sign-in logs (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. See log analysis.

Does Siemserva cover CVEs and missing patches?

Yes. It reports CVEs and missing patches across your devices, ranked by real-world risk with CISA KEV and EPSS. See CVE and patch management or search the CVE reference.

Why bring configuration, patching, and logs into one model?

Because risk lives in the overlap. A weak setting on an unpatched account that is also being probed in your sign-in logs is far more dangerous than any one of those alone, but separate tools never see it. Siemserva holds configuration, patching and CVEs, and logs in one connected model, so it ranks that real risk and the AI can reason across your whole estate. See the unified security model.

Is there a free way to try it?

Yes. The Advanced Microsoft 365 Security Simulator and the game are free, no registration or key needed. Registering free unlocks scans of 3 of your own tenants, up to 25 users each, in one verified scan. Education institution and nonprofit discounts are available, and full evaluation keys are available on request, reviewed and verified.

Does it work for MSPs and many tenants?

Yes. Siemserva is multi-tenant and MSP-ready, with bulk tenant audits and unified, client-ready reporting across many customers.

How does the AI work, and does it cost extra?

Siemserva is built for AI from the ground up and runs great without it: every scan delivers deep analysis and production-ready remediation with no AI or API key required. Turn it on for our market-leading MCP: six AI-enhanced report types (Detailed, Compliance, Business, Remediation, Audit, Portfolio), live tenant Q&A from Claude or the AI of your choice, and agent-mode remediation that lands as Microsoft Graph PowerShell SDK v2 scripts your admins already trust. You bring your own model, so there is no AI markup, and the rich data model keeps calls and cost low. See Senserva Trustworthy AI and the MCP and Claude.

What does it cost?

Pricing scales by tenant size, education institution and nonprofit discounts are available, and MSP pricing is available. Full evaluation keys are available on request. Contact info@senserva.com.

Is Siemserva audit-ready?

Yes, by design. Every finding ships with the source data Siemserva used to detect it, the control mapping it satisfies or fails, and a validated remediation step, mapped to every major framework and the verticals your auditor cares about. See the full compliance reference.

AI you can trust, on by choice

Siemserva is built for AI from the ground up and runs fully without it: every check and finding is deterministic, so a result never depends on a model. Turn AI on and it does the heavy lifting, AI-enhanced reports, plain-language tenant Q&A, and agent-mode remediation, and every output is grounded in your real scan data and Senserva-validated before you act.
