Every day the security industry misses maliciousness, but Cylance finds it… all without signatures, heuristics, behavioral analysis, sandboxing, etc.. Cylance (www.cylance.com), is using advanced mathematics and neural type algorithms to discern good from bad data and stop the execution of bad before it has an opportunity to run. No more Malware!
