I love how simple it makes creating rules for my VPNs (OpenVPN in particular). As well as being able create some quite complex routing/NATing scenarios using just one tool! The UI can be somewhat clunky at times - not sure if this was down more of an issue between releases than anything else but would expect better performance from something priced so high anyway? If you're looking into getting yourself ready should have your own private cloud setup which will make deploying any new features much easier too because they are self contained tools rather then relying upon 3rd party products like CloudFlare does out there now days :) Have been playing around doing various things here such has NAT throught Openvpn tunnels etc without having used their dedicated servers before until recently when we moved over our services onto them due issues previously mentioned above.
