I am aware of the directory sync to help control user accounts from a corporate environment up to the control hub. One thing I haven't seen available is the ability to limit access to the control hub administrative portal.
Is there anyway to limit access to the actual admin portal login interface to a corporate network? Maybe to an external proxy within a corporate environment?
You can control what access the user has in the Hub, by giving them full admin access or Sales access so they cant actually make changes. You can do this by finding the user and clicking the three dots and changing the access they have. Hope this helps
