Caci International, Inc.
CACI International doesn't need a lot of clients, just a few with deep pockets. As one of the largest government IT contractors, CACI derives most of its revenue from the US government (including about two-thirds from the US Department of Defense). CACI provides a wide range of technology services, including systems integration, network management, knowledge management, engineering, and simulation. It helps federal agencies provide national security, secure information systems and networks, and enhance data collection and analysis. CACI also serves state and local governments, as well as commercial customers. It operates internationally through subsidiary CACI Limited and CACI BV.
