Microsoft Security Copilot

Microsoft Security Copilot is Microsoft's enterprise AI for security operations, deeply integrated across the Microsoft Defender, Sentinel, Entra, Intune, and Purview product lines. Rather than a standalone tool, Security Copilot is a cross-product agent layer that lets analysts and IT admins query Microsoft's full security telemetry in natural language: investigate incidents in Defender XDR, build KQL queries in Sentinel, audit identity risks in Entra, manage device compliance in Intune, and resolve Purview data-loss incidents — all from one prompt-first interface. The pricing model is consumption-based via Security Compute Units (SCUs); Microsoft 365 E5 customers receive 400 SCUs/mo per 1,000 user licenses (capped at 10,000 SCUs/mo) included, and additional capacity can be provisioned. The platform also exposes pre-built AI agents — Phishing Triage, Conditional Access Optimization, Vulnerability Remediation — that work autonomously inside the Defender product surfaces. For organizations already on the Microsoft security stack, Security Copilot is the lowest-friction way to add agentic AI to a SOC; for organizations evaluating purely best-of-breed alternatives, the Microsoft tax (M365 E5 dependency) is the major adoption gate.
