Semperis expands Microsoft ties with Sentinel integration

Summary

Semperis and Microsoft have deepened their collaboration, with Semperis bringing its Lightning Platform into the Microsoft security ecosystem. The effort gives security analysts identity context inside the tools they already use. The companies describe the goal as helping analysts investigate faster, hunt more effectively, and act on identity risk within existing workflows.

Identity has become central to attack paths across hybrid environments, and insight into it often sits outside the analyst workflow. The collaboration centers on protecting the identity fabric, described as the security control plane for organizations adopting agentic AI. It builds on a longstanding relationship that includes Semperis' membership in the Microsoft Intelligent Security Association and its designation as a Microsoft Certified Security Software vendor.

The integration uses Microsoft-native building blocks, including Azure Functions, DCE/DCR, Log Analytics workspace tables, KQL, Security Copilot, and MCP. Lightning-derived identity context, such as attack paths, Tier 0 exposure, posture indicators, and broader hybrid identity telemetry, appears directly within Microsoft Sentinel. Analysts can query, correlate, and act on that context without leaving the Microsoft security environment.

Semperis has also built custom Security Copilot agents that operate within the Microsoft security stack and use KQL-based tools over Lightning tables in Sentinel. The agents return structured risk and posture summaries, identify exposed paths and Tier 0 proximity, and answer higher-order questions. In the companies' model, Sentinel serves as the central analytics and hunting plane, while Security Copilot adds an AI-assisted investigation layer on top.

“Security teams do not need more disconnected tools,” said Semperis CEO Mickey Bresman. “They need the identity context that helps them understand what matters, what is exposed, and where to act first. By bringing the Semperis Lightning Platform into Microsoft Sentinel and Security Copilot, we are helping customers operationalize identity risk inside the workflows their SOC teams already trust.”

“Security teams need identity context within the tools they already use.” said Jesse Kopavi, principal program manager, Microsoft Sentinel at Microsoft. The agents may be published through the Microsoft Security Store, which would let joint customers discover, deploy, and operate them within Microsoft's ecosystem.
