Implementing mobile device management (MDM) provides the best method for maintaining the security of corporate applications pushed to employee-owned mobile devices. MDM allows organizations to apply security policies, manage applications, and ensure data protection on these devices. It offers comprehensive control over various aspects of device security, such as configuring settings, enforcing security policies, monitoring compliance, and performing remote actions like wiping data if necessary. This makes MDM a robust solution for maintaining secure corporate application access and usage on employee-owned devices.
