ManageEngine Patch Manager Plus automates patching across Windows, macOS, Linux, and hundreds of third-party applications. Siemserva is the independent patch double-check and the Microsoft 365 posture layer.
ManageEngine Patch Manager Plus, from Zoho, automates the full patch cycle for operating systems and a large catalog of third-party applications, on-premises or as a cloud service. It deploys patches well. Siemserva complements it with an independent verification of patch coverage across Microsoft's own APIs and whatever tools you run, plus deep Microsoft 365 configuration posture and compliance that a patch tool does not cover.
Siemserva runs standalone for full Microsoft 365 posture across configurations, logs, and CVEs, or right alongside ManageEngine Patch Manager Plus.
| What ManageEngine Patch Manager Plus does well | Where teams want more |
|---|---|
| Automated patching for Windows, macOS, Linux, and 850+ third-party applications. | A deployment tool reports its own actions, not an independent cross-tool check. |
| Available both on-premises and as a cloud service. | Microsoft 365, Entra ID, and Purview tenant posture is out of scope. |
| Test-and-approve workflows, decline rules, and scheduled deployment windows. | No native mapping to Microsoft compliance baselines like SCuBA or MCSB. |
| Patch compliance dashboards and detailed deployment reporting. | Patch gaps that fall between tools are hard to see from one console. |
| Capability | ManageEngine Patch Manager Plus | Siemserva |
|---|---|---|

| CVE risk ranking | Vendor severity | MSRC, CISA KEV, EPSS |
| Compliance evidence | Patch-focused | Mapped to frameworks |

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.
ManageEngine Patch Manager Plus, from Zoho, automates the full patch cycle, detection, testing, approval, deployment, and reporting, for operating systems and a large third-party application catalog. It is available both on-premises and as a cloud service.
Patch Manager Plus covers Windows, macOS, and Linux plus 850-plus third-party applications, with test-and-approve workflows and decline rules that suit organizations needing controlled rollout. It is also available within the broader Endpoint Central suite.
On-prem and cloud options, plus distribution features for remote and branch offices, make it adaptable to different infrastructure constraints, a reason it is popular with mid-market IT teams.
Patch Manager Plus reports patch compliance for what it manages. An independent double-check across Microsoft's APIs, with CVE enrichment that ranks gaps by exploitability, adds assurance across the whole estate.
No. ManageEngine deploys patches; Siemserva independently verifies coverage across Microsoft's APIs and adds Microsoft 365 configuration posture and compliance.
Siemserva reads patch state through Microsoft's own APIs, Azure Update Manager, Intune via Microsoft Graph, and Defender TVM, so it confirms the end result on the device regardless of which tool applied the update.
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.
