What it checks

Device enrollment restrictions control which device types, platforms, and OS versions are allowed to enroll in Intune management. Without proper restrictions, users could enroll personal devices running unsupported or vulnerable operating system versions, expanding the attack surface. Enrollment restrictions also prevent unauthorized device types from gaining access to corporate resources through device management.

Recommended value

Block personally owned devices or limit to specific platforms; enforce minimum OS version requirements; limit per-user device enrollment count

Remediation

Review the device enrollment restrictions in Intune and configure platform-specific restrictions that align with your organization's supported device policy. Set minimum operating system version requirements for each platform and configure the maximum number of devices a single user can enroll to prevent abuse. If corporate-owned device enrollment is preferred, block personally owned device enrollment and direct users to use app protection policies for BYOD scenarios.
