Microsoft Security Copilot leverages OpenAI's GPT-4 model and Microsoft's proprietary security model trained on global threat intelligence to enhance threat detection, analysis, and response capabilities. It integrates with Microsoft security products like Defender XDR, Sentinel, Intune, Entra, and Purview, along with third-party solutions through plugins. The tool provides real-time threat monitoring, automated vulnerability management, and cloud environment protection. Features include generating incident summaries, reverse-engineering malicious scripts, creating KQL queries through natural language, automating patch deployment, and providing remediation guidance. Users can access it through a web interface or Microsoft security dashboards, with preprocessing and post-processing workflows that contextualize prompts using organizational data and threat intelligence for accurate responses.
