ESEI started in the private sector with a focus on electric, oil and gas, and water companies. For clients in these industries, ESEI has designed and managed the implementation of complex interstate microwave radio systems, fiber optic networks, and tandem telephone systems.

We have also developed a large variety of secure web based applications to supervise and control critical transmission grid switching (SCADA), and to track network inventory and cellular telephone costs

Since 2003, we have established a solid presence in the Defense Industry. From our office in Sierra Vista, AZ we have taken our commercial telecommunications and information technology expertise and migrated into the Command, Control, Communications, Computers and Intelligence (C4I) world within the Department of Defense.

We are providing telecommunications management support for the Kuwait Iraq Communication Commercialization effort, engineering analysis for the Army's Future Telecommunications and IT Infrastructure requirements, engineering and installation support for the Enterprise System Technology Activity in Southwest Asia, as well as providing intelligence training support to the Army Intelligence School and Test and Evaluation support for new army systems.

ESEI has successfully provided telecommunications, database, and data networking solutions for public safety and educational institutions. In the public safety arena, ESEI has built radio systems to serve police and fire applications. For the educational community, ESEI has designed and implemented secure voice, data, and video networks for campuses and districts of all sizes through vehicles such as E-rate.
