Fix Recommendation

If a third-party unmanaged VPN app is installed on the iOS 18 device, do not configure the VPN app with a DOD network VPN profile.

Check Contents

Review the list of unmanaged apps installed on the iPhone and iPad and determine if any unmanaged third-party VPN clients are installed. If so, 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:
1. Open the Settings app.
2. Tap "General".
3. Tap the "VPN and Device Management" line and determine if any "Personal VPN" exists.
4. If not, the requirement has been met.
5. If there are personal VPNs, open each VPN app. Review the list of VPN profiles configured on the VPN client.
6. Verify no DOD network VPN profiles are configured on the VPN client.

If any third-party unmanaged VPN apps are installed (personal VPN) and they 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.
