First-time honoree recognized for 140% three-year growth; Cloud Range provides live-fire cyber attack simulation training for enterprise security teams

Inc., the leading media brand and playbook for the entrepreneurs and business leaders shaping our future, today announced that Cloud Range, the leading enterprise cyber range simulation platform for reducing detection and response times thereby reducing cyber risk, is No. 1181 on the annual Inc. 5000 list, the most prestigious ranking of the fastest-growing private companies in America. The list provides a data-driven snapshot of the most successful companies within the economy’s most dynamic segment—its independent, entrepreneurial businesses. Past honorees include companies such as Microsoft, Meta, Chobani, Under Armour, Timberland, Oracle, and Patagonia.

“We’re honored to be named to the Inc. 5000 list. It’s a powerful validation of the hard work our team has put into transforming how cybersecurity professionals train for real-world threats, ultimately reducing the likelihood of a devastating breach,” said Debbie Gordon, Founder and CEO of Cloud Range. “This recognition reflects the growing demand for proactive, hands-on cyber defense skills and the critical role simulation-based training plays in preparing organizations to respond to today’s advanced attacks. It’s exciting to see the market embracing a new standard in readiness and resilience.”

This year’s Inc. 5000 honorees have demonstrated exceptional growth while navigating economic uncertainty, inflationary pressure, and a fluctuating labor market. Among the top 500 companies on the list, the median three-year revenue growth rate reached 1,552 percent, and those companies have collectively added more than 48,678 jobs to the U.S. economy over the past three years.

“Making the Inc. 5000 is always a remarkable achievement, but earning a spot this year speaks volumes about a company’s tenacity and clarity of vision,” says Mike Hofman, editor-in-chief of Inc. “These businesses have thrived amid rising costs, shifting global dynamics, and constant change. They didn’t just weather the storm—they grew through it, and their stories are a powerful reminder that the entrepreneurial spirit is the engine of the U.S. economy.”

Inc. will celebrate the honorees at the 2025 Inc. 5000 Conference & Gala, taking place October 22–24 in Phoenix, and the top 500 will be listed in the Fall issue of Inc. magazine.
