A little birdy told me, that in products like Threatfire and I would assume DriveSentry, that the majority of detection comes from the AV engine and not the behavior-based engine. Which all in all, is a great combo. What I want to see is a product that can accomplish their detections rates based on a behavior-based engine alone. Maybe, just maybe, one is on the way. ". However, our preliminary testing results indicate that for true behavior-based software competitors, our detection numbers are better than all we’ve tested against." Cant say anymore then that for now.
