Dependent on battlefield work for much of its revenue, ManTech continued this year to shift into new markets. The company, which focuses on services for the military and intelligence agencies, has sought to expand its cybersecurity footprint and took steps to enter the commercial market with its purchase of Sacramento-based cybersecurity business HBGary. ManTech also acquired Herndon-based Evolvent to boost its health information technology work.


ManTech was one of the first technology firms on the battlefield in 1990 in Desert Storm.
