When you first open an enterprise app that you've manually installed, you see a notification that the developer of the app isn't trusted on your device. You can dismiss this message, but then you can't open the app.
After you dismiss this message, you can establish trust for the app developer. Tap Settings > General > Profiles or Profiles & Device Management. Under the "Enterprise App" heading, you see a profile for the developer.
Tap the name of the developer profile under the Enterprise App heading to establish trust for this developer.
Then you see a prompt to confirm your choice. After you trust this profile, you can manually install other apps from the same developer and open them immediately. This developer remains trusted until you use the Delete App button to remove all apps from the developer.
