Are there role-based access and permission-controlled features in Korbyt?

Yes, Korbyt provides multiple roles tied to feature permissions.
When configuring a new user or editing an existing you will see the various roles available.
Each product that is part of your service will have a separate tab for a user’s permissions.
A user can have different roles in the different services.

A User’s Role will decide what functions they do and don’t have within the Content Management Systems.

User Groups can also be used to limit which content a CMS User has access to

For example, Frank is a Content Approver for Digital Signage, which would allow Frank to edit a Playlist.  Frank is also a member of the NYC Users Group, and through User Groups and Playlist Folder Permissions Frank can only see the NYC Playlists he is meant to edit.  Frank does not see the Playlists that are part of the LA Group

More information on how to set up Users, and User Groups is available in the Knowledge Base article – How to Manage CMS Users
