Security Copilot in Microsoft 365 E5

Microsoft Security Copilot is transforming how organizations protect, investigate, and respond to threats by embedding generative and agentic AI directly into security and IT operations. Now part of Microsoft 365 E5, Security Copilot brings AIpowered assistance and automation into the everyday tools security and IT teams already use across Microsoft Defender, Entra, Intune, and Purview — accelerating threat response, simplifying complex workflows, and improving security outcomes.

Microsoft partners play a critical role in helping customers adopt and scale Security Copilot as part of their E5 security strategy. With Security Copilot included for Microsoft 365 E5 customers, partners can drive faster timetovalue, deliver differentiated security services, and support more resilient, efficient security operations at scale—creating new opportunities to grow and expand E5based security practices.
