C3 has been named to the Inc. Regionals list of the fastest-growing private companies in the Mid-Atlantic, recognizing organizations that have demonstrated strong revenue growth and operational momentum.
ARLINGTON, Va., — April 1, 2026 — Inc., the leading media brand and playbook for the entrepreneurs and business leaders shaping our future, today revealed that C3, a cybersecurity and compliance provider focused on the Defense Industrial Base (DIB), has been ranked No. 92 on its sixth annual Inc. Regionals: Mid-Atlantic list – the most prestigious ranking of the fastest-growing privately held companies in the Mid-Atlantic. The region includes Delaware, Maryland, the District of Columbia, Virginia, West Virginia, and North Carolina.
An extension of the national Inc. 5000 list, the Regionals list offers a data-driven look at the independent small businesses driving growth across the Mid-Atlantic economy. Companies on this year’s list demonstrate exceptional revenue expansion, resilience, and job creation during a challenging economic period.
“Making this list reflects the growing demand for cybersecurity and compliance expertise across the defense industrial base,” said Marc Pantoni, CEO, C3 Integrated Solutions. “Defense contractors are navigating complex regulatory expectations while continuing to support critical national security missions. Our focus is helping organizations build environments that are secure, compliant, and sustainable over the long term.”
Between 2022 and 2024, these 137 private companies had a median growth rate of 74 percent; by 2024, they’d also added 8,399 jobs and $10.6 billion to the region’s economy.
Complete results of the Inc. Regionals: Mid-Atlantic, including company profiles and an interactive database sortable by industry and metro area, will be available beginning March 31 at: https://www.inc.com/regionals/mid-atlantic.
“The honorees on this year’s Inc. Regionals list achieved exceptional growth at a time when the odds were against them. Amid inflation, supply chain disruptions, and ongoing economic uncertainty, they didn’t just persevere – they innovated, adapted, and thrived. Their resilience made them standouts in their industries and true growth engines in their regions,” said Bonny Ghosh, editorial director at Inc.

Methodology
The Inc. Regionals lists are ranked according to percentage revenue growth over two years. To qualify, companies must have been founded and generating revenue by March 31, 2022. They had to be U.S.-based, privately held, for-profit, and independent—not subsidiaries or divisions of other companies—as of December 31, 2024. (Since then, a number of companies on the list may have gone public or been acquired.) The minimum revenue required for 2022 is $100,000; the minimum for 2024 is $1 million. As always, Inc. reserves the right to decline applicants for subjective reasons.
