The SigFree SDK allows you to develop applications capable of identifying and dealing with malware, even self-modifying malware, as soon as itâ??trade;s launched â?? at DayZero. SigFree is signature free, does not rely on string-matching and does not slow you down. SigFree can detect suspect code even employing polymorphism, encryption, metamorphism, self-modifying, anti-disassembly, and anti-emulation. DayZero and SigFree change the trade-off dilemma between effectiveness and cost which faces malware protection today. What had been too expensive to implement for true zero day protection in the past is made feasible today with SigFree.
