It was a while ago, but with process injection being very common nowadays, it won't help you much blocking untrusted processes from communicating. The Bitdefender way of doing it is far better, focusing on untrusted websites blocked in all apps, rather than blocking app by app.Yeah right. The Norton one is even better in some context. Norton can even be set up to ask only if an unknown/suspicious program tries to connect. They probably do that by default. Norton's firewall is superb.
