Aviv Raff knows a thing or two about cybersecurity. He’s chief technology officer at Seculert, which specializes in helping companies detect and stop sophisticated cyber attacks. In the wake of recent megabreaches such as the one at JPMorgan Chase (JPM), where hackers compromised personal information of some 76 million households, or Home Depot (HD), where the digital intruders got at about 56 million credit and debit card numbers, Raff says no one can afford to be complacent about digital safety. “Awareness is definitely rising, but there are people out there who still think it might not happen to them,” he says. “Everyone is at risk of being compromised.”
