E5 tenants receive 400 Security Compute Units (SCUs) per month for every 1,000 licensed users, up to a cap of 10,000 SCUs. The allocation scales proportionally for smaller tenants. Unused SCUs reset each month and don't roll over.

|---|---|
| 400 | 160 |
| 1,000 | 400 |
| 4,000 | 1,600 |
| 25,000+ | 10,000 (cap) |
What it covers: Chat, promptbooks, and agents across Purview, Defender, Entra, Intune, Sentinel, and the Security Copilot portal.
Setup: Auto-provisioned for E5 tenants. No Azure configuration required.
Need more? Additional SCUs are available at $6/SCU. Non-E5 customers can also purchase Security Copilot standalone at this rate.
