Cyber security breaches seem to flood the headlines on a weekly basis. The state of play has made FireEye Chairman and CEO Dave DeWalt issue a stark warning about the dangers that companies and governments are facing around the world.

"Cybersecurity has never been more important," DeWalt said in an interview on CNBC's "Fast Money" on Thursday. "The danger is never more real."

DeWalt said his company is currently "at an inflection point," just as the dialogue surrounding cyber security and cyber terrorism in America is reaching an inflection point.

In a speech at the White House summit on cyber security and consumer protection at Stanford University on Friday, President Barack Obama outlined the need to beef up the country's technological barricades, a situation made all too real by massive intrusions at U.S. businesses, resulting in major losses and bad press.

"These attacks are getting more and more sophisticated every day, so we've got to be just as fast and flexible and nimble in constantly evolving our defenses," Obama said. The president also signed an executive order Friday to promote information sharing on cyber threats between private sector companies and the government.

That ups the ante for FireEye, which sees dangerous yet potentially lucrative times for its business.

"We see a massive market opportunity in cybersecurity," Dewalt said on Thursday. "The threat levels are changing nearly every day. Now we're starting to see sabotage terrorism and, really, acts of war around the world in the cyberspace."

High-profile hacks at companies such as JPMorgan, Target and Sony have made it a boom time to be in the business of putting out cyber fires. A new report from digital security company Gemalto found that more than one billion records were compromised last year alone.

DeWalt's company has been called in to handle some of the most highly publicized cases of the past two years. That publicity, coupled with an increased awareness of a changing threat landscape, has helped FireEye's business grow exponentially, he said.
