Core

MESSAGE FROM THE CEO Murphy’s Law—“Anything that can go wrong will go wrong”—may sound right. And it feels safer to delegate cybersecurity decisions to techies. But the fact is that far more incidents can happen than will happen. So, you might overspend to defend against incidents that only “can” happen while leaving yourself wide open to incidents that “will” happen. And because techies are not fiduciaries, you are left liable for their decisions. Core offers you a solution to your problem. Wayne Shaw Founder and CEO, CORE, K.K. Contact: info@coresecurity.co.jp
