With the problems that have been reported about the newer versions of both these popular Firewalls, I was just wondering which of these two offered better protection? Kerio 4.2.2 Free which I personally use and have no problems with, (Unlike 4.3.268 on my Two User Account) has with some setting changes, passed at least 5 of the leak tests on firewallleaktest web site. I have also read where ZA Free 6.1.744 passed several as well, with users of that version having none of the problems reported in the last two versions of that Firewall. What ever is going on with both of these Firewalls, at the very least needs to be addressed and fixed much faster than like in the past. It is almost, in my opinion, shameful that anyone should even want to compare these two older versions because they are fearful of using the newest ones. I realize there are many people who do use the newest versions of both without any problems, but my point is that apparently the older versions still seem to have less problems than the newer ones. At least this is how I see it from what I have read on various web sites. I will add that I do have a life beyond Firewalls. This all started by doing some research on Firewalls to replace my Windows XP one, and as I did, it slowly amazed me how it seemed there were more problems caused by using a Firewall that offers outbound protection, than using one that doesn't. I'm not talking about any caused by the user either.
