Atera is an accessible all-in-one RMM/PSA. Siemserva adds the Microsoft 365 security posture and compliance layer it is not built for.
Atera is a popular all-in-one RMM and PSA, known for a simple model and AI features for IT operations. It manages endpoints and tickets. Siemserva complements it with deep Microsoft 365 tenant posture, compliance evidence, and an independent patch double-check across clients.
Siemserva runs standalone for full Microsoft 365 posture across configurations, logs, and CVEs, or right alongside Atera.
| What Atera does well | Where teams want more |
|---|---|
| Simple, all-in-one RMM and PSA. | Operations and endpoint focused, not Microsoft 365 tenant posture. |
| Accessible pricing and fast onboarding. | Entra ID, Intune, and Purview auditing is out of scope. |
| Endpoint management and patching. | No native Microsoft compliance-framework mapping. |
| Growing AI-assisted IT features. | Patch reporting is internal, not independent. |
| Capability | Atera | Siemserva |

| Per-tenant M365 posture | Limited | 650+ checks |

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.
