In a movie heist, there's always a gap between when the intruders break in and when they make off with the goods.

That also applies to digital heists, said Cybereason cofounder and CEO Lior Div, who publicly unveiled his digital security startup on Tuesday after spending three years in stealth mode.

“It probably took the Target hackers a while to understand what was going on inside that operation,” said Div in a recent interview with VentureBeat. “You can expedite the process in some way if you have prior information about the network and the layout, but we are saying that with our approach, we can catch it."

Cybereason's software monitors digital activities inside an enterprise, continuously searching for suspicious activity. But it's not just focused on prevention, which Div bills as important but insufficient; the company's core competency is helping breached organizations prevent major damages.

If Cybereason detects suspicious activity, it will alert security analysts with a detailed, visual report. It will also provide a series of suggestions aimed at eradicating the breach.

"The fundamental change between our approach and other companies," said Div, is that "we are assuming that the user doesn’t know how to ask the right questions."
