General Dynamics Information Technology, known as GDIT, is the technology services division of the defence contractor General Dynamics and one of the largest suppliers of IT to the United States federal government. It designs, builds and operates networks, cloud environments, cybersecurity and mission applications for defence, intelligence, homeland security and civilian agencies, work that requires a very large security-cleared workforce. The division roughly doubled in scale through the 2018 acquisition of CSRA, and has since concentrated on cloud migration, zero trust architecture and applying artificial intelligence inside accredited government environments.
