Review the list of unmanaged apps installed on the iPhone and iPad and determine if any third-party VPN clients are installed. If yes, verify the VPN app is not configured with a DoD network (work) VPN profile. This validation procedure is performed on the iOS device only. On the iPhone and iPad, do the following: 1. Open the Settings app. 2. Tap "General". 3. In the "VPN" line, determine if any "Personal VPN" exists. 4. If not, the requirement has been met. 5. If so, open each VPN app. Review the list of VPN profiles configured on the VPN client. 6. Verify there are no DoD network VPN profiles configured on the VPN client. If any third-party unmanaged VPN apps are installed (personal VPN) and have a DoD network VPN profile configured on the client, this is a finding. Note: This setting cannot be managed by the MDM administrator and is a User Based Enforcement (UBE) requirement.
