GK Sierra

Founded in 2007, Washington, D.C.- and Portland-based private military company GK Sierra started out producing secure communication technology for the U.S. government. Two years later, the firm, which is a wing of Genoa-Knowlton, Inc., started offering investigation and intelligence options among its services. At present GK Sierra gathers intelligence for the CIA. As well as having a Tel-Aviv office, the company is said to employ high-ranking Mossad operatives, which has led to accusations that it is in fact part of the Israeli Intelligence Service – allegations that GK Sierra has emphatically rejected. The company’s specialties include corporate investigation and intelligence, digital forensics, and encryption technology, while it is also purported to have “direct action” operatives on the ground in various countries around the world.
