Having been going back and forth between ThreatFire and Mamutu which I think along with Prevx are very nice programs. It dawned on me that the Community Protection they offer have to differ to some degree in the that there has to be more users of one product than the other. Prevx has been around the longest and PC Tools is well known, but Mamutu is the new kid on the block and I'm not sure how well known Emsi Software is yet. Comodo will also soon get into the Community based arena with ThreatCast and I would think they now have a very large following. Of course I realize it all boils down to 0 Day protection and how well each HIPS app does it's job. But having used all the ones I mentioned I will say that each ran very well for me and that I liked everyone of them. I guess the question is. How important is the Community Protection some security apps offer and is it really that important? Please no bashing of any programs so we can have a nice discussion about this if some want. Thanks.
