Hi Don, Yes there is. Configuration, Administrators. Create an Administrator and assign the Administrator their own Domain. There are lots of tick boxes for the rights you give that Admin. Remember their IP address will need to be added to the ACL also. Its not perfect as this Admin you create can still see some stuff you may not want them to see as vSZ is not quite 100% multitenant yet - really you are better off keeping them out if you can for the moment. I use it to provide a managed service to multiple customers - that works well. Oh, nearly forgot - MVNO can work too.
