Ivanti (the home of Shavlik patching) is strong at patch management. Siemserva is the independent patch double-check and the Microsoft 365 posture layer, and we proudly complement Ivanti's customers.
Ivanti is a major endpoint and patch management vendor, the long-term home of the Shavlik patch technology Senserva's founder originally built. We have deep respect for that lineage. Siemserva does not replace Ivanti; it complements it with an independent patch verification across Microsoft's APIs and deep Microsoft 365 configuration posture and compliance.
Siemserva runs standalone for full Microsoft 365 posture across configurations, logs, and CVEs, or right alongside Ivanti.
| What Ivanti does well | Where teams want more |
|---|---|
| Mature, broad patch management (including the Shavlik heritage). | Patch and endpoint focused, not Microsoft 365 tenant configuration posture. |
| Endpoint management and security across many platforms. | Entra ID, Intune, and Purview auditing is not its core. |
| Large enterprise install base and OEM relationships. | Patch reporting is internal to the deployment tool. |
| Deep third-party patch catalog. | Microsoft-native compliance mapping (MCSB, SCuBA) is limited. |
| Capability | Ivanti | Siemserva |
|---|---|---|
| Patch management and deployment | Core strength | Does not deploy |
| Independent patch verification | Self-reported | Cross-tool double-check |
| M365 / Entra / Intune / Purview posture | Limited | 650+ checks |
| Cross-tool unified patch report | No | Yes |
| Microsoft compliance mapping | Limited | Native |

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.
Ivanti's patch lineage runs through Shavlik, a pioneer of Windows and third-party patch management. That heritage lives on in Ivanti's patch products, which remain a respected, deep option for organizations that take patching seriously.
Ivanti patches the operating system and a broad catalog of third-party applications, on-prem and cloud, with the granular control that enterprises with complex change processes often need. Coverage breadth and maturity are its hallmarks.
Ivanti has expanded patch into the broader Neurons platform, spanning unified endpoint management, risk-based patch management, and IT service and asset management, positioning patch within a wider operations suite.
For the many organizations and OEMs that rely on Ivanti or Shavlik patching, an independent posture and patch-verification layer, reading device state through Microsoft's APIs and adding Microsoft 365 configuration coverage, complements rather than competes with the deployment work.
No. Ivanti deploys patches and manages endpoints; Siemserva independently verifies patch coverage and adds Microsoft 365 posture and compliance. We complement Ivanti and Shavlik customers.
Senserva founder Mark Shavlik created the original Shavlik patch technology, which lives on at Ivanti. See our Shavlik story for the full history.
