As compared to other non-hips firewalls, for example those contained in Avira or Eset? Is it the same principal? I guess what I am asking is if I just load the enhanced ruleset, is that enough protection? I keep waiting for the other shoe to drop. The reason I ask is because after a couple of days, this thing is SILENT. I forget it's there. And it runs sooo light. I keep thinking I am doing/have done something wrong. FWIW, I am running with Defensewall 3 (firewall on).
