Admins can indeed define particular groups for which Google Drive files can be link-shared. This will help ensure the security of the data and make it easy for users to share files with the right colleagues.
Based on beta release feedback below changes have been made.
Increased the maximum number of target audiences you can recommend from three to five.
Admins can add any group as a target audience, including groups belonging to different organizations
Why should you use it?
Administrators may formerly opt to allow users to link-share files to their entire domain or to someone with the link. Target audiences allow administrators to identify and propose users with more granular link-sharing options. This will lead to:
- Improve your organization’s security posture by making it harder for information to be shared more broadly than is appropriate.
- Guide users to share with more specific and appropriate audiences.
- Save users time by reducing the need to manage sharing requests from multiple individuals.
- Make it easier for your users to collaborate with their colleagues simply, efficiently, and securely.
Admins can assign target audiences at the group or OU level.
Admin console > Directory > Target audiences
End users will see target audiences available to them as link-sharing options for Drive, as indicated in the image above.
