Among defense contractors, QinetiQ North America is known for spy-world connections and an eye-popping product line. Its contributions to national security include secret satellites, drones and software used by U.S. special forces in Afghanistan and the Middle East.

Former CIA Director George Tenet was a director of the company from 2006 to 2008 and former Pentagon spy chief Stephen Cambone headed a major division. Its U.K. parent was created as a spinoff of a government weapons laboratory that inspired Q's lab in Ian Fleming's James Bond thrillers, a connection QinetiQ (pronounced kin-EH-tic) still touts.

QinetiQ's espionage expertise didn't keep Chinese cyber-spies from outwitting the company. In a three-year operation, hackers linked to China's military infiltrated QinetiQ's computers and compromised most if not all of the company's research. At one point, they logged into the company's network by taking advantage of a security flaw identified months earlier and never fixed.
