Understanding the Concept

Microsoft Security Copilot is an AI-powered assistant that helps analysts investigate incidents, hunt threats, and understand security posture. It integrates into the Defender XDR portal and uses natural language processing.

Copilot can summarize incidents, analyze scripts, generate KQL queries from natural language, explain alerts in plain language, and provide remediation guidance.

Licensed via Security Compute Units (SCUs) on a capacity basis. Administrators manage capacity, configure plugins, and control access through RBAC.
