Configure Duo Security integration for iOS devices

Perform the following steps to let Duo Security determine the trust status of your iOS devices.
  1. From the menu sidebar, go to Setup > System setup > Duo Security and then configure the settings for the SCEP CA server as provided by Duo Security.
  2. Add a Duo device certificate configuration to the iOS device profile you are using for your iOS devices.
  3. Update the iOS device profile on the devices.

This installs a Duo device certificate on the devices. The Duo Mobile iOS app detects the certificate and classifies the devices as trusted.
