 ## User Enrollment
 
 Microsoft Defender for Endpoint iOS can now be deployed on Intune User Enrolled devices. This new feature offers security and IT teams the flexibility to deploy Defender for Endpoint for iOS to user-enrolled devices so that work data and applications are protected, while end-user privacy is upheld on those devices.
