Qualys is a established vulnerability and compliance platform. Siemserva focuses on Microsoft 365 configuration posture with native Microsoft compliance mapping.
Qualys (VMDR, Policy Compliance) is a long-standing cloud platform for vulnerability management and broad compliance scanning across infrastructure. Siemserva is complementary and Microsoft-specialized: it audits Microsoft 365 configuration posture with native MCSB and CISA SCuBA mapping, and verifies patch coverage across Microsoft's APIs.
Siemserva runs standalone for full Microsoft 365 posture across configurations, logs, and CVEs, or right alongside Qualys.
| What Qualys does well | Where teams want more |
|---|---|
| Established cloud vulnerability management (VMDR). | Infrastructure-centric; Microsoft 365 SaaS configuration is not its focus. |
| Broad infrastructure and policy-compliance scanning. | Entra ID, Intune, and Purview posture is shallow compared to a Microsoft-native tool. |
| Large control library across many standards. | Microsoft-specific baselines (MCSB, SCuBA) are not native. |
| Scales across big, mixed environments. | No agentic remediation for Microsoft 365 misconfigurations. |
| Capability | Qualys | Siemserva |
|---|---|---|
| Infrastructure vulnerability management | Core strength | Not a vuln scanner |
| M365 configuration posture | Limited | 650+ checks |
| Native MCSB / CISA SCuBA mapping | No | Yes |
| Agentic M365 remediation | 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.
Qualys is a long-established cloud security and compliance platform, best known for VMDR, Vulnerability Management, Detection, and Response. Delivered from the cloud with lightweight Cloud Agents and scanners, it continuously finds and assesses vulnerabilities across hybrid environments.
Qualys spans asset inventory, vulnerability management, policy compliance, patch management, web application scanning, and cloud security from a single agent and console. That breadth makes it a consolidation play for security and compliance teams.
VMDR closes the loop from detecting a vulnerability to prioritizing it with threat intelligence to deploying the patch, aiming to shorten the time between discovery and fix within the Qualys platform.
Qualys centers on vulnerabilities and compliance across infrastructure and endpoints. Deep Microsoft 365 configuration posture, Conditional Access, identity, and workload settings mapped to MCSB and CISA SCuBA, is an adjacent, complementary specialty.
No. Qualys does infrastructure vulnerability and policy compliance; Siemserva specializes in Microsoft 365 configuration posture and Microsoft-native compliance mapping.
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.
