Entity in EMM: In an EMM context, an entity can be a mobile device (like a smartphone or tablet), a user profile, or even an application that's managed by the system.
Deregistration Process: When you deregister an entity from an EMM platform, you're essentially revoking its management privileges or removing it from the system's control.
For Devices: Deregistering a device means removing its configuration profiles, policies, applications, and other management settings enforced by the EMM platform.
For Users: Deregistering a user profile might involve revoking access to certain enterprise resources, removing associated device management settings, or deactivating associated licenses or privileges.
Technical Mechanisms:
Communication: The EMM platform typically communicates with managed entities through a combination of protocols like Mobile Device Management (MDM), Mobile Application Management (MAM), and Mobile Content Management (MCM).
Commands: EMM platforms send commands (often using protocols like MQTT, HTTP/HTTPS, or proprietary protocols) to devices or applications to enforce policies, install or remove apps, or collect information.
Feedback & Acknowledgment: After sending a deregister command, the EMM platform expects feedback or acknowledgment from the device or user profile. This ensures that the deregistration process is complete and the entity is no longer under management.
Reasons for Deregistration:
Lost/Stolen Devices: If a managed device is lost or stolen, it's crucial to deregister it from the EMM platform to prevent unauthorized access to corporate resources.
Employee Departure: When an employee leaves an organization, their devices and user profiles might be deregistered from the EMM platform to ensure data security and compliance.
Policy Changes: If there's a change in organizational policies or strategies, certain devices, applications, or users might need to be deregistered from the EMM platform.
Impact:
Device/Entity State: After deregistration, the device or entity might revert to its default settings or a state where it's no longer managed by the EMM platform.
Data & Access: Depending on the EMM platform's configuration, deregistration might also lead to data wipe processes to ensure data security.
