Many of these companies are taking different approaches to combating cyber crime including crowdsourcing, machine learning and a focus on network endpoints.
Investment opportunities in the industry have become attractive not only because of the increase in cyber crimes, but the increase in everyday items that are now connected to the internet. With the proliferation of data and access points, cyber security will only increase in importance. Investors at least are making that bet.
In 2014—a year in which cyberthieves stole customer information from at least four Fortune 500 companies—venture capitalists invested a record amount in privately held companies in the cybersecurity industry. Venture-backed companies in the U.S. that provide cybersecurity technology or services raised $1.77 billion from investors last year, topping the previous high of $1.62 billion set in 2000 during the dot-com boom, according to industry tracker Dow Jones VentureSource. Globally, venture-backed cybersecurity companies raised $1.9 billion last year, also a record. Cybersecurity has become an unending arms race, with companies and governments trying to protect themselves against attackers that include organized crime and increasingly nation-states.
