Microsoft Defender for Cloud is a strong CSPM and workload-protection platform for Azure and multicloud infrastructure. Siemserva covers the Microsoft 365, Intune, Entra ID, CVEs, and Purview configuration layer that cloud-workload posture does not. They are better together.
Microsoft Defender for Cloud is excellent at what it is built for: cloud security posture management and workload protection across Azure, AWS, and GCP resources, with a Secure Score for those resources and a regulatory compliance dashboard. That is the infrastructure layer. It is not the same thing as the configuration of your Microsoft 365 tenant, your Entra ID identity and privileged-access policies, your Intune device compliance, or your Purview data protection. Siemserva is built for exactly that SaaS configuration layer. Run both and you cover cloud workloads and the Microsoft 365 tenant in one story, instead of assuming one covers the other.
Siemserva runs standalone for full Microsoft 365 posture across configurations, logs, and CVEs, or right alongside Microsoft Defender for Cloud.
| What Microsoft Defender for Cloud does well | Where teams want more |
|---|---|
| Strong cloud security posture management (CSPM) for Azure, AWS, and GCP resources. | Centers on cloud infrastructure and workloads, not Microsoft 365 SaaS configuration. |
| Workload protection for servers, containers, databases, and storage. | Limited depth on Entra ID identity and privileged-access posture, Intune device configuration, and Purview data protection. |
| Secure Score and a regulatory compliance dashboard for cloud infrastructure. | No AI-generated, validated remediation tuned to your Microsoft 365 tenant state. |
| Deeply integrated with Azure and the wider Microsoft Defender stack. | Built for the Azure-centric enterprise, not lightweight single-tenant or MSP multi-tenant Microsoft 365 review. |
| Capability | Microsoft Defender for Cloud | Siemserva |
|---|---|---|
| Cloud workload protection (servers, containers) | Core strength | Not a workload protector |
| Azure and multicloud resource posture | Core strength | Out of scope |
| Microsoft 365 and Entra ID configuration posture | Limited | Core strength |
| Intune device and Purview data posture | Limited | Built in |
| AI-generated, validated remediation | No | Yes |
| Lightweight, agentless, MSP multi-tenant | Enterprise / Azure-centric | Yes |

Every finding, and the full graph behind it, is yours. Through the Senserva SDK, the open database and the rich Claude MCP you get complete access to the underlying Siemserva data, so you, or Claude, 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.
It is easy to assume that because both carry the Microsoft and Defender names, Defender for Cloud also covers Microsoft 365. It does not. Defender for Cloud is about the resources you run in Azure and other clouds: virtual machines, containers, databases, storage. Microsoft 365 configuration, who holds privileged Entra ID roles, whether Conditional Access is sound, how Intune enforces device compliance, how Purview protects data, is a separate layer, and that is the layer Siemserva owns.
Defender for Cloud gives you a Secure Score for cloud resources. Siemserva gives you ranked findings for the Microsoft 365 tenant and, for each one, AI-generated remediation that Senserva validates before you apply it. A number tells you where you stand; a validated fix moves you forward.
Defender for Cloud shines in the large, Azure-centric enterprise. Siemserva is built so a one-person IT team, a mid-market security program, and an MSP managing many tenants can all assess Microsoft 365 in minutes, agentlessly, with reporting tuned to each audience.
Run Defender for Cloud for cloud workloads and Siemserva for the Microsoft 365 tenant, and you close the blind spot each leaves on its own. Infrastructure posture and SaaS configuration posture, side by side, with remediation you can actually act on.
No. Microsoft Defender for Cloud is cloud security posture management and workload protection for Azure and multicloud infrastructure. Defender for Office 365 is email and collaboration security. Siemserva is different again: it assesses the configuration of your Microsoft 365, Intune, Entra ID, and Purview tenant.
No. They cover different layers. Defender for Cloud secures cloud infrastructure and workloads. Siemserva secures the Microsoft 365 tenant configuration, identity, devices, and data. Most organizations benefit from both.
Because a clean cloud-workload posture says nothing about whether your Entra ID privileged roles, Conditional Access, Intune compliance policies, or Purview labels are configured safely. Siemserva assesses that Microsoft 365 configuration layer and tells you how to fix what it finds.
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. 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.
Yes. Findings are mapped to key frameworks and are audit-ready on the first scan, with AI-enhanced reports a security manager or an auditor can read directly.
"They're surfacing blind spots other tools miss, and their AI-first reporting gives the platform a true voice, helping organizations understand not just what's at risk, but what to do about it."
