 ## About project visibility
 
-Projects can be public or private. For public projects, everyone on the internet can view the project. For private projects, only users granted at least read access can see the project.
+Project visibility can be set to {% ifversion ghec %}private, internal when using an {% data variables.enterprise.prodname_emu_enterprise %}, or public if your enterprise does not use {% data variables.enterprise.prodname_managed_users %}{% else %}public or private{% endif %}. For public projects, everyone on the internet can view the project. For private projects, only users granted at least read access can see the project. {% ifversion ghec %} For internal projects, other members of your enterprise can see the project.{% endif %}
 
 Only the project visibility is affected; to view an item on the project, someone must have the required permissions for the repository that the item belongs to. Only people with access to a private repository will be able to view project items from that private repository.

 Project admins and organization owners can control project visibility. Organization owners{% ifversion project-visibility-policy %} and enterprise owners{% endif %} can restrict the ability to change project visibility to just organization owners.
 
-In public and private projects, insights are only visible to users with write permissions for the project.
+In public{% ifversion ghec %}, internal, {% endif %} and private projects, insights are only visible to users with write permissions for the project.

 Project admins can also manage write and admin access to their project and control read access for individual users. For more information, see "[AUTOTITLE](/issues/planning-and-tracking-with-projects/managing-your-project/managing-access-to-your-projects)."
