I'll have to disagree with that statement. I just finished installing sophos utm essential firewall and was able activate Endpoint Protection. I have the same question as far as endpoint licensed users.
The UTM license itself allows for 9999 connections and 999999 bandwidth.
I've never found the Essential Firewall to be very useful, as most features are disabled. If you are serious about security for your business, you're much better off paying for a business license and having access to all of the features.
