About Aptnexus LLC
Aptnexus LLC, an SBA 8(a) certified small disadvantaged business and black American-owned company based in Accokeek, Maryland, operates as a federal prime contractor (92% of recent awards) delivering cybersecurity compliance, security assessment, information assurance, and IT modernization services across civilian and defense agencies. The company is a Subchapter S corporation with SBA 8(a) certification through September 2029.
Aptnexus holds a seat on two transformational vehicles that dominate its potential-value profile. Most significantly, the company was awarded a $151 billion multiple-award IDIQ under the Scalable Homeland Innovative Enterprise Layered Defense (SHIELD) contract issued by the Missile Defense Agency on December 29, 2025, with a ten-year performance period through December 2035. The SHIELD vehicle is a full-and-open (no set-aside) competition structured to support research, development, prototyping, systems engineering, test and evaluation, and modernization across air, missile, space, cyber, and hybrid threat domains, with work spanning classified and unclassified programs. Aptnexus also holds a seat on the 8(a) STARS III GWAC (GSA Federal Acquisition Service, awarded February 2022, ceiling $50 billion, completion July 2029), a competitive 8(a) set-aside vehicle from which it has executed three task orders totaling roughly $939 thousand. A third vehicle — the GSA Multiple Award Schedule (MAS) — was awarded September 2025 with a $100 thousand ceiling through September 2030. Aptnexus offers 17 active labor categories on the GSA Schedule spanning cybersecurity assessment, compliance, privacy, IT project management, and helpdesk support, with hourly rates ranging from $69.32 (junior helpdesk/desktop support) to $159.46 (senior IT project manager and subject-matter expert roles); all positions require a bachelor's degree, and security-cleared roles are available across the portfolio.
Recent capability work reflects a civilian-agency focus anchored to cybersecurity and compliance. Representative prime awards include a $6.4 million firm-fixed-price definitive contract awarded by the Bureau of Engraving and Printing on May 5, 2025 (8(a) Sole Source, completion November 2026) for cybersecurity compliance and privacy program support covering security program management and analytical support to protect agency assets; a $441 thousand delivery order from the Internal Revenue Service under 8(a) STARS III (September 2024) for FISMA compliance security assessment services supporting on-premises and cloud solutions; and a $248 thousand order from the National Assessment Governing Board under STARS III (September 2023) for security assessment and Authority to Operate services for www.nagb.gov. Historical work includes a $669 thousand 8(a) Sole Source definitive contract with the United States Trade and Development Agency (August 2021, completed December 2022) for Microsoft SharePoint and records management implementation.
Customer concentration is heavily weighted toward GSA (driven by the vehicle ceilings) and the Trade and Development Agency by award count. The top five customer agencies account for 92% of all awards, but the ranking splits sharply by potential value versus count: GSA Federal Acquisition Service anchors 100% of combined potential value due to the SHIELD and MAS vehicles, while the United States Trade and Development Agency, the Bureau of Engraving and Printing, the IRS, and the National Assessment Governing Board represent the operative customer set by transactional volume and actual obligated spend. Only $8.3 million has been obligated across the entire award portfolio — less than 0.02% of combined potential value — reflecting the early-stage nature of the SHIELD ceiling and the small scale of task orders to date.
Activity has accelerated recently. Awards per year rose from one in 2021 to four in 2025, though the raw count remains modest at twelve total awards across the source period. One award (the Bureau of Engraving and Printing cybersecurity compliance contract, $6.4 million potential value) faces ultimate completion inside the next twenty-four months and therefore carries recompete exposure. Aptnexus functions predominantly as a prime (92% of awards) with minimal subcontractor engagement; the company serves as a named subcontractor on one award under Maximus Federal Services for IRS Masterfile system programming support and CI/CD pipeline leadership (November 2024). Service Contract Inventory reports minimal activity — seven SCI records total (three as prime, four as sub) from FY2022–FY2024 with zero invoiced revenue recorded in the SCI dataset and less than one FTE delivered per year on SCI-reportable contracts — indicating that Aptnexus's substantive federal revenue flows through firm-fixed-price contract vehicles, delivery orders, and labor-category scheduling rather than time-and-materials service contracts captured in SCI.
