I like that it's easy enough to set up your app or website as part of our firewall/proxy server at work so we can use them through corporate proxy servers without issue.
It also makes sure you have proper security in place if someone does manage to get access. Not much dislike about this software but maybe some would be better served by something else? If setting one site with multiple connections then this might not fit well because there are other products out there which do let us assign individual sites as they come online.
