Four new malware strains are created every second, and the banking industry is almost 300 times as likely to get attacked by malware as other types of businesses, according to Nayeem Islam, CEO of Blue Hexagon. That's why his deep-learning cybersecurity startup, which has been in stealth mode for a year and a half and officially launched Tuesday, is making financial services one of the primary industries it serves. The company has received $31 million in funding from the venture capital firms Benchmark and Altimeter Capital. Heffernan Insurance is its first public customer. Blue Hexagon uses self-learning technology to catch network threats, Islam said.
