Claude becomes an agentic security analyst for Microsoft 365. Siemserva ships the market-leading MCP, so you run all 650+ checks, compliance mapping, and agentic remediation from Claude, or the AI of your choice, in plain language. No KQL, no clicking through portals. Or hand the AI the full Senserva security data model and let it build its own audits and threat-hunting exercises.

A quick install puts the real Claude on a rich simulated tenant at no cost, so you can try the whole thing free. It stays low cost in production, too: you bring your own model, so there is no AI markup, and the rich data model means the AI answers from real findings with fewer calls. Run your own tenant with a key. One longtime customer retired their home-grown PowerShell scripts and now lets Siemserva and Claude handle remediation, reclaiming around 80 percent of the hours they used to spend on hand-rolled tooling.

Under the hood, Siemserva builds your tenant as a living graph, 110+ node tables and 70+ edge tables capturing identity, devices, apps, roles, Conditional Access, patches, and CVEs, and the relationships between them. That structure is why scans are richer and the AI is smarter: it reasons across how your environment actually connects, not a flat checklist, so answers and remediations reflect real blast radius and root cause. The same graph drives continuous security drift management, and the platform comes from founder Mark Shavlik, who built HfNetChk and MBSA at Shavlik Technologies.
