CrowdStrike is a leader in endpoint and threat protection. Siemserva covers the Microsoft 365, Intune, Entra ID (logs included), CVEs, and Purview configuration layer that EDR does not. They are better together.
This is not an either/or. CrowdStrike Falcon watches what is happening on your endpoints and in your environment in real time. Siemserva audits how your Microsoft 365 tenant is configured, the misconfigurations and identity risks that let an attack succeed in the first place. Most mature teams want both.
Siemserva runs standalone for full Microsoft 365 posture across configurations, logs, and CVEs, or right alongside CrowdStrike.
| What CrowdStrike does well | Where teams want more |
|---|---|
| Best-in-class endpoint detection and response (EDR/XDR) with a lightweight agent. | Falcon centers on runtime threats and endpoints, not deep Microsoft 365 / Entra ID / Intune / Purview configuration posture. |
| Excellent threat intelligence and managed threat hunting (Falcon Complete). | SaaS and M365 misconfiguration coverage is lighter than a Microsoft-focused posture tool. |
| Broad platform: identity protection, cloud, and exposure modules. | Identity Threat Protection is a separate module and licensing tier. |
| Strong incident response reputation and large install base. | Platform breadth and cost can be heavy for teams that mainly need Microsoft posture and compliance. |
| Capability | CrowdStrike | Siemserva |

| M365 / Entra / Intune / Purview config posture | Limited | 650+ checks |
| Compliance control mapping (MCSB, SCuBA, more) | Limited | Native |
| Agentic remediation of misconfigurations | No | Yes |
| Claude MCP interface | No | Yes |

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.
Most breaches are a chain: a user is phished, an identity is misused, a foothold is gained, then lateral movement and impact. CrowdStrike is strongest at the later stages, detecting and stopping malicious behavior on endpoints and across the environment in real time. Siemserva is strongest at the front of the chain, the Conditional Access gap, the standing privileged role, the legacy authentication still enabled, the misconfiguration that let the phish land in the first place. Close those and there is less for any EDR to catch.
CrowdStrike sees process execution, endpoint telemetry, identity threat signals, and network behavior. Siemserva sees configuration and posture: how MFA and Conditional Access are scoped, which roles are standing versus eligible in PIM, how Intune compliance and BitLocker are set, where SharePoint and OneDrive overshare, and whether Purview audit logging is healthy. Different data, different questions, and together a fuller picture than either alone.
A common setup: CrowdStrike for detection and response on endpoints and identities, Siemserva for continuous Microsoft 365 configuration posture, compliance evidence, and remediation. A Siemserva finding, say a Conditional Access bypass or a risky OAuth grant, often explains how an incident CrowdStrike flagged became possible, and hands the team the fix instead of just the alert.
CrowdStrike is a broad, premium platform. If your priority is Microsoft 365 posture and compliance rather than full endpoint EDR, Siemserva covers that layer with no agents and no cloud service, and native MCSB and CISA SCuBA mapping. Many teams keep CrowdStrike for what only an EDR can do and add Siemserva instead of buying extra Microsoft-posture modules.
No, and we are clear about that. Siemserva is not an EDR. It covers the Microsoft 365 configuration and identity posture layer that sits in front of those threats. Keep CrowdStrike for detection; add Siemserva for posture and compliance.
Yes. CrowdStrike handles runtime detection; Siemserva hardens the Microsoft 365 configuration so there is less for an attacker to exploit, and gives you the compliance evidence.
Depth and breadth on Microsoft 365 posture, native compliance mapping, agentic remediation, and a unique choice of a full UI or a full Claude MCP interface. Senserva is a Microsoft Intelligent Security Association (MISA) member and a 2024 Microsoft Security Excellence Awards finalist. The Microsoft security layer is our specialty, not a side feature.
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.
"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."
