Microsoft Sentinel for detection, Siemserva for posture

Sentinel watches what is happening. Siemserva hardens the configuration so there is less to detect. Better together.

Microsoft Sentinel is a powerful cloud-native SIEM and SOAR. It detects and responds to threats; Siemserva reduces the misconfigurations that let threats succeed. Siemserva has achieved Microsoft Sentinel integration approval, so configuration posture and detection work together.

How Siemserva makes it better

Siemserva runs standalone for full Microsoft 365 posture across configurations, logs, and CVEs, or right alongside Microsoft Sentinel.

What Microsoft Sentinel does wellWhere teams want more
Scalable cloud-native SIEM and SOAR.A SIEM detects activity; it does not audit and fix configuration posture.
Deep Microsoft ecosystem and threat-intelligence integration.Microsoft 365 misconfiguration coverage is not its focus.
Powerful analytics, hunting, and automation.Tuning and cost require investment.
Centralized incident response.Prevention-side hardening is out of scope.

Your data, and a model you can build on

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.

A closer look

Cloud-native SIEM and SOAR

Microsoft Sentinel is a scalable, cloud-native SIEM with built-in SOAR, running on Azure Log Analytics. It ingests logs from Microsoft 365, Azure, and a large catalog of third-party sources, then detects, investigates, and responds to threats across the estate.

Detection and hunting with KQL

Analytics rules and proactive hunting queries are written in Kusto Query Language (KQL), and detections map to the MITRE ATT&CK framework. The combination of rich data and a powerful query language is what makes Sentinel strong for threat detection and investigation.

Automation and response playbooks

SOAR playbooks, built on Azure Logic Apps, automate response: enrich an alert, open a ticket, disable an account, or isolate a device without manual steps. Automation rules orchestrate how incidents are triaged and assigned.

Data, cost, and what feeds it

Sentinel's value depends on the data flowing into it, and ingestion drives cost, so connector selection and tuning matter. It is a detection-and-response platform; the quality of the configuration and posture data it receives shapes how much it can catch.

Frequently asked

Does Siemserva replace Sentinel?

No. Sentinel is detection and response; Siemserva is configuration posture and compliance. They are complementary, and integration is approved.

Do I need to install agents or grant broad access?

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.

Can I try Siemserva before I buy?

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.

Does Siemserva work for MSPs and multiple tenants?

Yes. It supports multi-tenant and MSP fleets, with bulk tenant security audits and unified, client-ready reporting across many customers.

How does Siemserva use AI, and does it cost extra?

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.
