Security Copilot inclusion in Microsoft 365 E5 subscription..The future of cybersecurity is here!


At Ignite 2025, Microsoft is announcing that Security Copilot agents will be directly built into the flow of work for security teams using Microsoft Defender, Microsoft Entra, Microsoft Intune, and Microsoft Purview.

A dozen new agents are introduced across these products, to bring agentic defense across workflows, enabling autonomous and proactive protection.

To make the agents easily accessible and help security teams get started more quickly, we’re excited to announce that Security Copilot will be available to all Microsoft 365 E5 customers.

Rollout starts November 18, 2025, for existing Security Copilot customers with Microsoft 365 E5 as of November 18, 2025, and will continue in the upcoming months for all Microsoft 365 E5 customers. Customers will receive a 30-day advanced notification before activation. For more information on what’s included, see What capacity is included?.

Welcome to a new era of cybersecurity: where security is ambient and autonomous, with agents built-in, easy-to-use, and ready to empower your team to stay ahead of threats.
