A feature of the BlackBerry Enterprise Server (BES) that separates personal and corporate activity in a BlackBerry device. It enables the company to manage the apps for its BlackBerry users independent of the user's personal needs. A personal app cannot update the data in a corporate app and vice versa. If an employee leaves the company, the work side can be deleted, keeping the personal side intact. See
