The purpose of a mobile device management (MDM) system is to secure and manage mobile devices used within an organization. MDM enables IT departments to enforce security policies, monitor device compliance, and remotely manage applications and data. This system protects sensitive information by implementing controls like data encryption and the ability to remotely wipe devices if lost or stolen. Additionally, MDM facilitates the deployment of apps and updates, ensuring employees have access to necessary tools securely. Overall, MDM enhances productivity while safeguarding the organizational ecosystem.
