Leidos Holdings, Inc.
A technology and engineering firm that builds mission software, cybersecurity, and health systems for U.S. government agencies, plus defense hardware like unmanned maritime vehicles. It also makes the airport baggage and body scanners used at checkpoints around the world. Born in 1969 as the employee-owned science consultancy SAIC, it split into Leidos in 2013, taking a name clipped from "kaleidoscope" to echo the way it blends solutions from many angles.
