About S2I2 Inc.
S2I2 Inc., an SBA 8(a) certified, minority-owned small disadvantaged business (Asian-Pacific American owned) headquartered in Oakton, Virginia, operates predominantly as a subcontractor (69% of awards) and prime contractor on defense and civilian IT infrastructure programs. The company specializes in enterprise technology services, cybersecurity infrastructure, endpoint security, data protection, and IT strategic consulting across the Department of Defense and subordinate commands.
S2I2's customer concentration is heavily weighted toward defense IT infrastructure. The Defense Information Systems Agency leads by award count (20 awards, $9.8 million combined potential value), but two large IDV seats dominate the dollar picture: the Defense Logistics Agency Land and Maritime customer (2 awards, $11.94 billion combined potential value) and the Department of the Navy Naval Sea Systems Command (2 awards, $4 billion combined potential value). These represent positions on the DLA J6 Enterprise Technology Services 2.0 (JETS 2.0) IDIQ and the Seaport Next Generation (Seaport-NxG) IDIQ respectively. The Department of the Army Corps of Engineers Engineer Research and Development Center and the Department of the Navy round out the active set. The top five customers account for all of S2I2's reported potential value.
S2I2 holds seats on four major contract vehicles. The Chief Information Officer—Solutions and Partners 3 (CIO-SP3) vehicle anchors the bulk of activity with 18 task orders. Alliant II carries 7 task orders, while JETS 2.0 and Seaport-NxG each have generated one or more task orders. Representative prime work includes a $4.5 million 8(a) sole-source IDC with the U.S. Army Corps of Engineers for IM/IT strategic consulting and technical writing services (with a $1.35 million task order through September 2025), a $4.49 million firm-fixed-price delivery order from the Defense Logistics Agency for Endpoint Security System Program support under JETS 2.0 (completion October 2027), an $8.83 million combined value in installation processing node resiliency and data protection work for the Defense Information Systems Agency (completed September 2024), and a $1.36 million 8(a) sole-source purchase order from the Department of the Navy for public internet services (completion February 2030). S2I2 also holds a position on the Scalable Homeland Innovative Enterprise Layered Defense (SHIELD) IDIQ, a $151 billion multiple-award vehicle issued by the Missile Defense Agency in December 2025, with an initial $500 delivery order.
Activity peaked in 2022 (19 awards) and has moderated since, averaging six awards per year across 2023–2025. One award with $4.5 million combined potential value reaches completion within the next twenty-four months, creating a recompete window. As a subcontractor, S2I2 performs predominantly for Science Applications International Corporation across DISA Joint Information Service Provider platform services and USACE Revolutionary Information Technology Services (RITS) with large-scale DoD expertise in network, data center, and cloud adoption. S2I2 also subcontracts to Empower AI Inc. on GSA digital transformation initiatives and to Capital Consulting Corp on Pentagon JSP next-generation IT services.
The company's category concentration aligns with IT infrastructure and cybersecurity work: Computer Systems Design Services dominates at 28 awards, with Other Computer Related Services, Engineering Services, and R&D in the Physical, Engineering, and Life Sciences representing secondary categories. GSA Multiple Award Schedule labor portfolio spans eight categories from Business Analyst ($92.76/hr, bachelor's degree, 2 years experience) through Enterprise Infrastructure Architect ($246.77/hr, bachelor's degree, 10 years experience), with no security-cleared roles offered. The SCI dataset shows S2I2 delivered approximately 18.5 FTEs on federal service contracts in FY2022 and 23.5 FTEs in FY2024, all in its subcontractor capacity; these figures represent only SCI-reportable work and exclude goods, products, classified contracts, and non-federal revenue. The company operates in full-and-open competition on its largest IDVs (JETS 2.0, Seaport-NxG, SHIELD) and leverages its 8(a) certification primarily on sole-source Army Corps of Engineers and Navy contracts.
