How Netclient Licensing Works

I am trying to determine my licensing needs for a network installation of Avast! on several clients using the ADNM. The technical matters are reasonably simple, but the licensing seems a bit cryptic to me (or at least not well documented). If I want to distribute the netclient my workstations do I need to purchase Avast Standard, Advanced, Pro, Enterprise or Internet Security Suite? Thanks in advance for your help with this matter.

I purchased 12 licences of the Standard Suite for our network managed antivirus. I believe that depending on the size of your network it may require something else though.
