You will now find more options in the ‘Permissions’ section in your Team settings modal. This is where team admins can set team permissions for inviting members, project access and prototype access if your team is on the Enterprise plan. With these permissions all your files can be completely private and only accessible to those with your company’s email domain.
In addition, all users on the Pro or Enterprise plan will now be able to make prototypes private on a project level as well as limit collaborators to only viewing prototypes. In your project, open the Share panel and check the box next to Private Link. If the prototype access has already been determined on a team level, you will see that reflected in the Share panel.
