Multiple settings in the policy configuration will help you to ensure the prevention of sharing work data in the personal container.
Go to miniOrange MDM dashboard -> Android -> Policies -> Select your policy -> Data Sharing.
This screen will give you all the possible options that you can set up to ensure data transfer prevention.
E.g. Set Copy Paste to option ‘Deny work to personal’ so any content copied from the work apps can’t be pasted in the personal container apps.
