What is Microsoft Security Copilot?

Microsoft Security Copilot is an AI-powered security assistant designed to help organisations detect, investigate, and respond to security threats more quickly. It works across Microsoft's security products, including Defender, Sentinel, and Entra, pulling together security data from your existing tools to provide faster threat analysis and recommended actions. The tool is built for security teams of all sizes, particularly those already using Microsoft's security suite. Rather than replacing your existing security tools, it sits on top of them, using machine learning to analyse threats, suggest responses, and reduce the time your team spends on manual investigation work. Notably, Security Copilot integrates Zero Trust principles and can handle identity management, network access, and data security tasks. It's positioned as a way to make security operations more efficient when you're managing multiple security products across cloud and on-premises environments.
