Posture check · Entra ID and hybrid
Users can create new tenants (T1136.003)
Non-admin users can create new Microsoft Entra tenants. The creator becomes Global Administrator of the new tenant, which sits outside your policies.
Why it matters
Tenants that nobody monitors can hold company data and identities. An attacker can also use one to stage activity.
