Past honorees include companies such as Microsoft, Meta, Chobani, Oracle, and Patagonia. The annual Inc. 5000 list recognizes the nation's fastest-growing independent businesses and highlights companies that have demonstrated strong revenue growth, resilience and momentum in competitive markets. C3's inclusion reflects continued demand for cybersecurity and compliance support across the Defense Industrial Base as contractors work to protect controlled unclassified information (CUI), strengthen IT operations and navigate evolving CMMC, DFARS and related cybersecurity requirements. C3 designs, implements and manages secure cloud, IT and security environments that help defense contractors protect CUI, prepare for CMMC assessments and maintain long-term operational resilience. The company's growth has been driven by its focus on helping customers shift from reactive compliance efforts to sustained operational maturity in real operating environments. "Being named to the Inc. 5000 reflects the work our team has done to help defense contractors meet one of the most complex cybersecurity and compliance challenges facing the market," said Marc Pantoni, CEO of C3. "Our customers need security and compliance support that holds up in real operating environments, not just on paper. This recognition reinforces the demand we're seeing for managed IT, cybersecurity and compliance solutions that help organizations protect sensitive defense information and build resilience over time."

From AI and advanced manufacturing to healthcare, consumer products, and professional services, these businesses are expanding their impact, creating jobs and proving that entrepreneurial ambition continues to fuel the U.S. economy.
