There is a way to restrict certain content within the Ploud system and that is to not publish the content and keep in in the 'Private' state. This way, content will only be viewable by staff members that are logged into the system.
We recommend that you create a 'Staff Only' folder somewhere on the website and keep the folder in the 'Private' state. Any content that you place in that folder will not be available to anonymous web visitors. In order for staff members to view the content within the Staff Only folder, they will need to be logged into the system with their account.
