The very first Kerio PF I have downloaded is the 4.1.3 version and I like it coz it really have made a big difference in my internet speed after I switched from ZoneAlarm. Web filtering feature is just not important coz I have some other software that take cares for that. Then comes the Kerio 4.2, but I was dismayed when I learned that the newly added HIPS feature was only available in their full version. After I learned that I have nothing to rejoice in this newer version coz I’m only using the free version then I was thinking of going back into 4.1.3 version. Is the Kerio 4.2 free “more protective” than 4.1.3 free version?
