Microsoft Defender XDR: Retirement of in-app OS update notifications in Defender for Endpoint (iOS)

Microsoft Defender for Endpoint on iOS will retire in-app OS update notifications by late July 2026, shifting OS update compliance and enforcement solely to Microsoft Intune and MDM/MAM. This removes duplicate messaging, requires no immediate action, and aims to simplify management and unify compliance across services.

[What and Why]

Microsoft Defender for Endpoint (MDE) on iOS is retiring in-app OS update notifications and recommendations. To improve consistency and reduce duplicate guidance, OS update compliance and enforcement will rely on Microsoft Intune and existing MDM/MAM capabilities instead of Defender in-app experiences. This change simplifies management for administrators and provides a more unified and secure compliance experience across Microsoft security and device management services. Intune driven OS update requirements will remain unaffected by this change.
