Won Chung

Won Chung serves as a key procurement professional within the Defense Information Systems Agency, supporting the agency’s mission to deliver secure, resilient, and interoperable information systems for global military operations. Responsible for managing complex IT and systems engineering acquisitions, Chung focuses on sustaining and modernizing the Department of Defense’s C4I infrastructure, with particular emphasis on cybersecurity, cloud modernization, and mission-critical IT services. Their procurement portfolio centers on high-stakes, mission-driven contracts that ensure the integrity and availability of defense communications networks, often requiring compliance with NIST, FISMA, and DoD Cybersecurity Maturity Model Certification standards. Chung maintains a consistent working relationship with EXPRESSION NETWORKS LLC, a primary contractor delivering specialized computer systems design and IT services. This partnership reflects a pattern of sustained collaboration with vendors capable of supporting integrated, high-assurance IT environments, including network architecture, systems integration, and technical consulting. The relationship is characterized by repeat engagements and a focus on performance-based outcomes, indicating a preference for proven, capable partners with deep domain expertise in defense IT ecosystems. Chung’s procurement activity shows no reliance on socioeconomic set-asides, with 100% of awards issued under full and open competition. This reflects a strategic prioritization of technical capability and mission readiness over socioeconomic preferences, aligning with DISA’s operational imperatives to rapidly deploy secure, scalable solutions without contractual constraints that may delay delivery. The primary NAICS categories under Chung’s purview are 541519 (Other Computer Related Services) and 541512 (Computer Systems Design Services), with a secondary focus on 541611 (Administrative Management Consulting). These reflect a specialization in enterprise IT modernization, systems architecture, and mission support services—particularly in cloud migration, secure infrastructure design, and C4I sustainment—demanding vendors with proven experience in DoD environments and defense-grade cybersecurity protocols.
