Time and again i have held off for the longest periods before trying a new firewall myself. My latest attempt was with COMMODO, another free-firewall where i have seen mixed reviews.
And as always, i have returned yet again to KERIO 2.15! I'm sure there are others who find excellent capabilities with the more popular to the more expensive, but i yet to run across another that performs with such precision and perfection with 100% stability as found with the old Kerio.
When and if i do, i'll be the first to make my own change known along with the reasons. In the meantime KERIO remains CHAMPION on ALL my units.
