shedding some light

As a By Light company, CESI leverages one of the leading providers of innovative IT, infrastructure solutions, and full spectrum cyberspace operations for U.S. Federal and State Government agencies.

To meet these needs, By Light has grown substantially in the past few years, both organically and through strategic acquisitions such as CESI. By Light has built a strong portfolio, stepping to the forefront of cutting-edge technology in key market growth areas of IT and Cyberspace Operations and Security; Network Services, Integration, and Operations; Cloud and Managed Services; Artificial Intelligence; Software Services; and Satellite and Wireless Communications.

simulation production
