The federal defense IT and consulting market remained highly competitive in Fiscal Year 2025. Acquisition timelines tightened, competition increased, and awards were concentrated among firms able to consistently secure obligated dollars.
Arctas, in cooperation with OrangeSlices and HigherGov, is launching the 2026 Vanguard Defense 250. This list provides a data-driven view of companies that captured federal civilian IT and consulting work during FY 2025.
The Arctas Vanguard Defense 250 is not based on nominations, surveys, or subjective rankings. Instead, it is built exclusively from federal contracting data and reflects reported FY 2025 obligated dollars, including both prime awards and reported subcontractor obligations. The analysis covers a defined set of federal IT and consulting services NAICS and PSC codes. HigherGov supports this analysis by tracking federal buying activity across agencies, contract vehicles, and award categories. Its ability to capture and organize obligation data at scale makes this type of market-level analysis possible. HigherGov is an innovative platform which integrates actionable Human and AI intelligence from dozens of real-time government and proprietary sources and combines it with reporting, management, and search tools to enable users to find and win contracts and grants, cultivate partnerships, and find expansion opportunities.
Past performance does not guarantee future results. However, the companies represented in the Arctas Vanguard Defense 250 demonstrate consistent participation and success in the federal civilian contracting market during FY 2025.

What is Next
On February 24, Arctas, OrangeSlices, and HigherGov will host Vanguard 250 GovCon Gamechangers, a one-hour virtual session focused on the question leaders immediately ask after seeing the list. Why these firms? Why now?
The conversation brings together a small group of highly respected GovCon advisors who collectively work across hundreds, and in some cases thousands, of companies. They see patterns form early, recognize shifts before they become obvious, and understand what separates firms that keep winning from those that stall.
In one fast-paced hour, these advisors will break down what the data is signaling, where leading firms are placing bets heading into 2026, and what the rest of the market can learn from the companies already winning.
This list is not about hype. It reflects who is winning, and why that matters.
