Sunbelt Personal Firewall

Kerio free (the actual name is Sunbelt Personal Firewall) is a simple personal firewall, light, but several tests on the control of outbound traffic is not as effective as others, and especially there is a considerable distance from his own version payment (same as Zone Alarm). It easy to configure, and even this is much appreciated by users looking for something ready or almost everything.

The free version available for non-professional-after 30 days lost many security functions (which only remain in the fee), although less than Zone Alarm, as shown by tests on safety.

Overall, however, there are currently firewall free to consider other level (Comodo and PCTools Firewall, for example), as from my test is if anything better than the free version of Zone Alarm.

NOTE: The downloadable version is in charge, after 30 days turns into free, losing the extra features.
