Secure Cross-Tenant Agent Interaction

When enterprise agents collaborate across corporate borders (e.g., Supplier agent talking to Manufacturer agent), security cannot rely on shared API keys. It demands Microsoft Entra ID Workload Identity Federation:

  • Mutual Trust: Tenants configure cross-tenant access settings and trust external Entra ID tenant IDs.
  • Granular Application Roles: Agents request minimal scopes like Agent.Delegate.ReadWrite.
  • Continuous Access Evaluation (CAE): Real-time token revocation if either tenant flags a security risk.
