SEP.cloud: Easy to get started?

Hi.  I traditionally go with on-premises SEPM for my customers however I have one that since we don't have a way to link their branch offices effectively to their head office, I imagine my next step is to go with the SEP .cloud (Symantec.cloud portfolio) .  The current head office network would remain using SEPM on premises but there are maybed 3 computers at each branch office that currently are just Unmanaged SEP clients. 

Has anybody worked with this before?  I am already a .cloud reseller with Email and Web Security stuff but haven't done anything with SEP yet. 

Thanks!  5 bucks says I know who will reply first!
