Illumio for Microsoft Sentinel: Unified, Graph-Powered Security at Cloud Scale

We’re excited to announce that Illumio has built new integrations into Microsoft’s updated Sentinel platform. Illumio for Microsoft Sentinel brings AI-powered breach containment to Microsoft’s cloud-scale security ecosystem.

The new integrations combine the power of Illumio Insights with Microsoft Sentinel data lake and graph, as well as with Microsoft Security Copilot to transform how security teams detect, investigate, and contain cyber threats.

With Illumio for Microsoft Sentinel, you can:

Get a unified, graph-based view of your entire security landscape.
Publish lateral traffic findings from Illumio directly into the Sentinel data lake.
Correlate traffic data with Microsoft products, including Microsoft Defender XDR and Microsoft Defender Threat Intelligence vulnerability data and Entra ID activity logs, as well as with other security product information.

And with the Illumio Security Copilot Agent now integrated directly into Microsoft Security Copilot, analysts can ask natural-language questions, uncover real threats fast, and take action — all without jumping between consoles or manually stitching together data.

See the new integration in action at the recent Microsoft Security event, featuring Illumio Founder and CEO, Andrew Rubin:

What’s inside Illumio for Microsoft Sentinel

Illumio for Microsoft Sentinel is built to deliver real-time threat detection, contextual intelligence, and rapid response without adding complexity for security teams.

The integrations include three core components. Together, they give security teams a unified view of risk, clear paths to containment, and powerful AI tools to respond built into the Microsoft Cloud ecosystem you already trust.

Illumio Insights

Illumio Insights is our AI-powered cloud detection and response (CDR) solution and a key component of the Illumio breach containment platform.

Built on the Illumio AI security graph, Insights monitors and protects every workload and resource across hybrid and multi-cloud environments. It visualizes high-risk or malicious traffic and behavior, prioritizes lateral movement risks, and helps security teams detect and respond to breaches faster.

Illumio for Microsoft Sentinel Data Lake Connector

Bring Illumio Insights data straight into the Microsoft Sentinel data lake. This enables analysts to use Illumio data to dig into lateral movement patterns, uncover high-risk pathways, and strengthen containment strategies.

Once it’s in the data lake, that information can be correlated with Defender XDR and Defender Threat Intelligence vulnerability data, Entra ID logs, and more to create a unified view of activity across hybrid environments.

Illumio セキュリティコパイロットエージェント

The Illumio Security Copilot Agent plugs Illumio Insights directly into the Microsoft Copilot for Security chat interface.

Analysts can explore Illumio events correlated with Microsoft security telemetry — no console hopping or manual alert matching required.

Smarter threat detection with faster response

What security teams need is smarter, connected intelligence that helps them turn alert noise into clear, actionable insights.

Traditional API-to-API connections are fragile and slow. Illumio for Microsoft Sentinel takes a different approach.

At the heart of Illumio for Microsoft Sentinel are two complementary security graphs that work better together:

The Microsoft Sentinel graph connects data across endpoints, apps, and threat intel to reveal known risks. ‍
The Illumio security graph tracks east-west traffic in real time to uncover threats moving laterally that other tools miss.

Together, these graphs give defenders an always-on lens into both static indicators of compromise and dynamic behavioral anomalies. This closes the security gaps attackers love to exploit.

On the right, analysts use Microsoft Secuity Copilot to ask questions and surface threat findings from Illumio Insights. On the left, Illumio maps the security graph and makes it easy to quarantine the threat before it spreads.

By using a graph-based model, this integration offers two powerful ways to work:

Low-code or no-code with AI chat: ask Copilot natural-language questions to instantly surface risks, gaps, and blast radiuses. ‍
Programmatic scale: use Jupyter notebooks and Apache Spark jobs to test threat hypotheses and operationalize rules faster at scale.

The result is faster detection, smarter response, and fewer security gaps across every layer of your defense.

Illumio + Microsoft: modern security at cloud scale and speed

Breaches aren’t a matter of if but when. Prevention alone isn’t enough. You have to detect, contain, and respond to breaches as fast as they can travel through your network.

This means that today’s organizations can’t rely on siloed tools or brittle connections. Security at cloud scale demands a unified, graph-powered security fabric.

Illumio for Microsoft Sentinel gives you that capability, combining the best of the Illumio breach containment platform with the Microsoft cloud-scale security ecosystem.
