NinjaOne is strong RMM and endpoint patching. Siemserva is the Microsoft 365 posture layer and the independent patch double-check, with unified reporting.
NinjaOne is a well-regarded RMM with autonomous Windows and third-party patching, patch caching, and good dashboards. Its own guidance notes that Microsoft 365-dedicated patch coverage is thin, and RMM is about managing endpoints, not auditing your Microsoft 365 tenant. Siemserva complements it: deep Microsoft 365 configuration posture plus an independent, cross-tool patch verification.
Siemserva runs standalone for full Microsoft 365 posture across configurations, logs, and CVEs, or right alongside NinjaOne.
| What NinjaOne does well | Where teams want more |
|---|---|
| Autonomous, zero-touch Windows and third-party application patching. | RMM manages endpoints; it does not audit Microsoft 365 / Entra ID / Intune / Purview configuration posture. |
| Patch caching and network optimization for distributed sites. | Microsoft 365-dedicated patch and security coverage is limited (per NinjaOne's own docs). |
| AI-assisted patch explanations and known-issue highlights. | Patch reporting is self-reported by the same tool that deploys. |
| Clean dashboards and MSP-friendly automation. | No native Microsoft compliance-framework mapping. |
| Capability | NinjaOne | Siemserva |
|---|---|---|
| RMM and endpoint patch deployment | Core strength | Does not deploy |
| M365 / Entra / Intune / Purview posture | Limited | 650+ checks |
| Independent cross-tool patch verification | Self-reported | Yes |
| Microsoft compliance mapping | No | MCSB, CISA SCuBA |
| Multi-tenant MSP fit | Yes | Yes |
Comparison reflects general capabilities at time of writing and is provided for research. Vendor features change; verify current specifics with each vendor.
Every finding, and the full graph behind it, is yours. Through the Senserva SDK and the Claude MCP you get complete access to the underlying Siemserva data, so you can query it, extend it, and build your own checks, reports, automation, and integrations on top. Nothing is locked away in a vendor cloud, and the data stays with you.
Siemserva does not just record pass or fail. It models your target environment, the identities, devices, applications, policies, and how they relate, as a queryable graph. That makes the data a foundation for new work: custom analysis, threat hunting, and automation, not a static checklist you read once and set aside.
NinjaOne is a modern, cloud-based remote monitoring and management (RMM) and endpoint management platform used by MSPs and internal IT teams. It combines monitoring, automation, remote access, and endpoint management in one console known for a clean, fast interface.
NinjaOne includes OS and third-party application patching as a core feature, automating updates across Windows, macOS, and a catalog of common apps, with reporting on patch compliance across managed endpoints.
Beyond patching, NinjaOne offers scripting and automation, software deployment, backup, and integrations with security tooling, positioning itself as a single pane for day-to-day endpoint operations.
RMM platforms manage and patch devices well. Independent verification of patch coverage with CVE context, plus Microsoft 365 cloud configuration posture, complements the operational view with a security and compliance lens.
No. NinjaOne is RMM and patch deployment; Siemserva is Microsoft 365 posture, compliance, and an independent patch verification. Use both.
Because deployment is not verification. Siemserva double-checks patch coverage across all your tools and Microsoft's APIs, and covers the Microsoft 365 configuration NinjaOne does not.
No agents and no cloud service. Siemserva reads your tenant through Microsoft's APIs and runs on Windows or Mac. You can explore the whole product first on the free Advanced Microsoft 365 Security Simulator, with no access to your environment at all.
Yes. The Advanced Microsoft 365 Security Simulator and the game let you explore a full scan, the findings, the AI, and the reports for free. Scanning your own tenant uses a license key, and 501(c)(3) nonprofits get the full version free.
Yes. It supports multi-tenant and MSP fleets, with bulk tenant security audits and unified, client-ready reporting across many customers.
Siemserva is built for AI from the ground up and also runs fully without it. Turn it on for AI-enhanced reports and to run the product from Claude, or the AI of your choice, via our market-leading MCP. You bring your own model, so there is no AI markup, and the rich data model keeps calls and cost low.
"For MSPs especially, it's the kind of engine that can turn a complicated tenant review into actionable next steps."
