Which solutions would best allow control over company emails on BYOD devices and limit data exfiltration?

The correct answer focuses on containerization as the solution that provides the best control over company emails on BYOD (Bring Your Own Device) devices while also limiting data exfiltration.

Containerization allows organizations to create a secure, separate environment within a personal device where company data, such as emails and applications, can reside independently from personal data and applications. This separation ensures that sensitive company data is protected and can be managed according to corporate policies. For example, IT can enforce policies that dictate how company emails are accessed and stored within the container, restricting functions like copy/paste or the ability to forward emails to personal accounts.

By using containerization, organizations can also apply specific security policies such as remote wipe, meaning if an employee leaves the company or loses their device, critical company data can be remotely deleted without affecting personal data. This control minimizes the risk of data exfiltration, where sensitive information could otherwise be inadvertently or deliberately transferred to insecure locations outside of company oversight.

Other options such as full-device encryption, network usage rules, and geofencing, while beneficial to an extent, do not specifically address the management of company email on BYOD devices or limit data exfiltration as effectively as containerization does. Full-device encryption secures
