Every computer system in the world is vulnerable to hackers and criminals, according to Marten Mickos, CEO of HackerOne. That's nothing new with major data breaches at Yahoo and the federal government.
But not to worry, teams of ethical hackers could be an answer to the growing cybersecurity concerns.
"There are far more ethical hackers, white hat hackers, in the world than criminals," Mickos told CNBC's "Squawk Alley" on Thursday. "So when you just invite the good guys to help you, you will always be safe. It's like a neighborhood watch. You're asking the good guys around you to help you see what's wrong with your system and help you fix it."
