About this agency
The Department of Homeland Security Office of the Chief Information Officer is a sub-agency within the civilian cabinet department, responsible for procuring and managing information technology and IT services to support DHS operations and missions across the department. The office transacts exclusively through federal contracts rather than grants.
The DHS CIO has awarded 2,165 federal contracts cumulatively since 2004, with $13.52 billion in combined potential value and $9.33 billion obligated to date (69% of potential). Recent activity shows 119 awards in 2022, 131 in 2023, 110 in 2024, 64 in 2025, and 75 year-to-date in 2026, reflecting a decline in annual volume over the past two years. The most recent recorded award date is September 30, 2026.
The prime contractor base is highly fragmented by award count over the last five years, with the top five contractors holding only 27% of recent awards. The One 23 Group Inc. leads by award count with 36 awards, followed by Peraton Technology Services Inc. with 32 and CACI NSS, LLC with 29. By combined potential value, concentration remains minimal at 8% for the top five, with ECS Federal, LLC leading at $309.9 million across 20 awards, CACI NSS, LLC at $270 million, and Peraton Technology Services Inc. at $224.2 million. The remaining 434 contractors collectively hold the substantial majority of value and award volume, indicating a highly distributed competitive landscape with no single dominant prime.
Set-asides are heavily skewed toward open competition: 75% of awards carry no set-aside designation. Of the 25% set-aside portion, small-business awards represent the largest cohort at 14% of total awards, followed by HUBZone at 5%, service-disabled veteran-owned small business at 2%, and 8(a) designations (sole source and competitive combined) at roughly 2%. Woman-owned and economically disadvantaged women-owned small business designations each account for less than 1% of the portfolio, as do HUBZone sole-source awards.
No recent contract opportunities are recorded against the DHS CIO in the source data; no grant activity occurs under this office.
