Microsoft Will Bundle Security Copilot With M365 Enterprise Licenses

### Executive summary — Microsoft announced at Ignite that Security Copilot will be automatically offered to Microsoft 365 E5 customers, with monthly Security Compute Unit (SCU) allotments tied to license counts (capped at 10,000 SCUs); the company also unveiled a set of new built-in agents for Defender, Entra, Intune and Purview, more than 30 third-party agents, and Agent 365 as a centralized registry/control plane to manage and secure AI agents — a move intended to accelerate enterprise adoption of AI-driven security capabilities while acknowledging limits for mid-size and smaller organizations due to cost and entitlement caps.
