Weak configurations cause
tenant compromise

With 10,000+ configuration details, the Microsoft 365 tenant attack
surface is vast and constantly expanding.

Weak configurations are a leading reason for tenant security breaches and yet Microsoft provides no way to benchmark a tenant configuration’s security, check it is hardened to repel attackers,
or ensure its resilience over time.
