Microsoft Security Copilot

What is Microsoft Security Copilot?

Microsoft Security Copilot is an AI assistant specialized in cybersecurity, built by Microsoft and available as an addition to the Microsoft Security product family (Sentinel, Defender, Entra). It democratizes security expertise: even analysts with less experience can perform complex threat analyses via plain language.

How does Security Copilot work?

Security Copilot integrates with the Microsoft Security platform and has access to security signals from Microsoft Sentinel (SIEM), Microsoft Defender (endpoint security), Entra ID (identity management) and Microsoft Purview (data risk management). This gives it a broad view of an organization's security posture.

Analysts can ask questions in plain language: "Give me a summary of all incidents from the past week with high priority" or "Analyze this suspicious IP address". Security Copilot searches the available data and provides a structured response with recommendations.
