ConnectWise recovery leaves MSPs with a tenant-proof problem

ConnectWise is moving towards phased service re-enrolment, but MSPs still need separate evidence that application identities did not establish persistence or access inside each managed Microsoft 365 tenant.

Executive consequence

ConnectWise’s Friday update moved the incident from broad suspension towards phased re-enrolment, while Microsoft quantified a wider Storm-0940 operation using the ARTEX agentic penetration-testing framework. The immediate CISO decision is not simply when to reconnect.

Decision today

Assign Entra administrators to review every tenant connected to Cloud Backup, not a representative sample.
