What is mobile device management and what policies does it enforce?

Mobile device management, or MDM, is a centralized platform that manages and secures smartphones, tablets, and laptops used in an organization. MDM enforces security policies including requiring device encryption, mandating screen lock with PIN or biometric, enforcing minimum operating system versions, controlling which applications can be installed, configuring VPN and Wi-Fi settings, enabling remote wipe if a device is lost or stolen, separating personal and corporate data through containerization, and restricting features like camera or Bluetooth in sensitive areas.
