Check summary
What this check verifies
Foreign group (outside the tenant) has a role assignment on the subscription
Why it matters
A group from outside your tenant has role access to your subscription. If the foreign tenant is compromised, attackers gain access to your Azure resources
How to fix it
Azure portal → Subscriptions → [subscription] → Access control (IAM) → Role assignments; filter to find the foreign group assignment (its tenant ID will differ from yours); contact the external tenant admin to confirm ongoing need; if not required, select the assignment and click Remove; review Entra External Identities → Cross-tenant access settings to restrict future external group grants
Siemserva flags every tenant where this check fails and, with Senserva Trustworthy AI remediation, can propose a validated fix you approve before it applies.
