What Global Systems Technologies, Inc. (GST) does

Global Systems Technologies, Inc. (GST) is a private, U.S.-based government contractor founded in 1993 and headquartered in Yardley, New Jersey, with an operational presence in Stafford, Virginia (the Galloway Office). The company provides engineering and IT services to federal agencies, with a primary customer base across the Department of Homeland Security (DHS), the Transportation Security Administration (TSA), the U.S. Navy, U.S. Army, and U.S. Air Force. GST has operated as one of the original contractors supporting the FAA / TSA Aviation Security R&D Laboratory at the W.J. Hughes Technical Center since the laboratory's opening, and it currently provides continuous support across six divisions of TSA's Office of Security Capabilities.

GST's service portfolio is organized around aviation and transportation security. Core offerings include Systems Engineering and Model Based Systems Engineering (MBSE), Research and Development, Test and Evaluation, Human Factors Engineering, Quality Management, Configuration Management, Integrated Logistics Support, Baggage Handling System simulation and design review, Cybersecurity (NIST 800 Series Risk Management Framework for Transportation Security Equipment), and the production and quality control of explosive simulants and trace standards used for certification testing of detection equipment. The company holds prime positions on the GSA Multiple Award Schedule (GS-10F-0461Y) and OASIS+ Technical and Engineering Domain (47QRCA25DU147) contract vehicles, and maintains ISO 9001:2015 certification through NQA.

GST is structured as a wholly-owned subsidiary of Joint Research and Development (JRAD), which acquired the company in 2025 to combine complementary test and evaluation, R&D, and systems engineering capabilities with sister company Sayres Defense under a unified Govcon platform led by CEO Tim Reardon. The company employs 101–250 people, has no public listing or external funding events, and earns revenue exclusively through federal professional services contracts — primarily cost-plus and fixed-price task orders — awarded through direct agency relationships and government-wide contract vehicles.
