This a supervised-only control. If the iPhone or iPad being reviewed is not supervised by the MDM, this control is automatically a finding.

If the iPhone or iPad being reviewed is supervised by the MDM, follow these procedures:

This check procedure is performed on both the device management tool and the iPhone and iPad device.

Note: If an organization has multiple configuration profiles, the check procedure must be performed on the relevant configuration profiles applicable to the scope of the review.

1. Open the Settings app.
2. Tap "General".
3. Tap "VPN & Device Management".
