Paradigm also added new Defense clients for ECS, including the Missile Defense Agency, the Navy’s Program Executive Officer for Integrated Warfare Systems, the United States Marine Corps, and the U.S. Marshals Service.
In 2012, ECS completed the acquisition of iLuMinA Solutions, Inc. iLuMinA brings large-scale Enterprise Resource Planning (ERP) software implementation and infrastructure design and development to ECS’ expanding capabilities.
