Microsoft Intune is a cloud-based unified endpoint management (UEM) solution for managing both corporate-owned and personally-owned devices and applications. The primary administrative interface for configuring and managing Intune is the Microsoft Endpoint Manager admin center. This web-based console unifies the management experience for Intune and Configuration Manager, providing a single place to create policies and manage devices. While Intune integrates heavily with Azure Active Directory for identity and access management, its specific device and application management functions are performed within the Endpoint Manager portal. The security and compliance centers serve different purposes related to threat protection and data governance, respectively.
