Cylance

Though cybersecurity firm Cylance has been working with high-profile clients such as Panasonic, The Gap and Toyota since its founding in 2012, it was a government agency that gave the Irvine, California-based company its biggest boost in 2016. That's when a congressional report concluded that Cylance played a pivotal role in discovering and stopping malware that caused the massive data breach at the Office of Personnel Management that stole the personal information of more than 20 million current and former government employees.
