There are lots of topics here talking bout what is the best firewall or favorite firewall, but haven’t heard yet what really are they are actually using. I mean, maybe those using only free versions of firewalls will be possibly hesitant (or shy ) to participate on that poll or topics because most of the time only “popular firewalls” are always on the list and talk about. Aside from that, also, even paid versions has its own flaws, blemishes, weaknesses, inadequacies and problems discovered as we used them day by day. Maybe my guess is right… but I could not say for sure if I am correct. What really are you actually using, free or paid versions of firewall?
