Private access groups let you create isolated content spaces within your organization. Unlike standard access groups where admins and owners can see all content, private access groups restrict visibility to only the members you explicitly add.
Standard access groupsAdmins and owners can see all content. Visible in access group lists to everyone. Content appears in search for admins.
Private access groupsOnly explicitly added members can see content. Hidden from non-members entirely. Content excluded from search for non-members.
