Which practice involves segmenting corporate-owned data from personal data on mobile devices?

Containerization is the practice that effectively segments corporate-owned data from personal data on mobile devices. This technique allows organizations to create a secure environment or "container" for corporate applications and data on a mobile device, ensuring that sensitive information remains protected while personal items are kept separate.

By utilizing containerization, businesses can enforce security policies specific to the corporate data, such as encryption, remote wipe capabilities, and access controls, without interfering with the personal use of the device. This separation is crucial for maintaining privacy for the user while also ensuring that the organization can protect its data from potential breaches or leaks.

In the context of mobile device management (MDM), containerization is especially important as it addresses the challenges posed by the use of personal devices for work purposes (often referred to as Bring Your Own Device, or BYOD). It enables a balance between functionality and security, which is paramount in today’s mobile-first environment.
