Nucleus Security Named to the 2026 Inc. 5000 List for Third Consecutive Year, the Most Prestigious Ranking of America's Fastest-Growing Private Companies
Company Ranked #1084, Earning a Place Among the Nation's Most Successful Independent Businesses
SARASOTA, Fla., Aug. 11, 2026 /PRNewswire/ -- Nucleus Security, the leader in unified exposure management, today announced it has been ranked No. 1084 on the 2026 Inc. 5000 list, the annual list of the fastest-growing private companies in America. The list is the most prestigious ranking of the nation's most successful independent and entrepreneurial businesses, recognizing companies that have achieved remarkable growth while driving innovation, creating jobs, and shaping the future of the economy.
"Making the Inc. 5000 again this year is a reflection of the trust our customers have placed in Nucleus and the work our team has done to solve a problem that continues to get harder as enterprise attack surfaces grow," said Steve Carter, co-founder and CEO of Nucleus Security. "Organizations don't need more vulnerability data; they need a better way to understand what matters, act faster, and know their exposure is being reduced. Our growth shows that this has become a business-critical priority for enterprises and government agencies alike."
This year's Inc. 5000 recognizes a new class of companies redefining what growth looks like. 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. Among the 5,000 companies on the list, the median three-year revenue growth rate was 130%, and those companies have collectively added more than 627,208 jobs to the U.S. economy over the past three years.

"Every company on the Inc. 5000 has a story of perseverance, smart decision making, and a refusal to sit still," says Mike Hofman, editor-in-chief of Inc. "Their growth reflects more than strong financial performance–it reflects creativity, resilience, and the customer focus required to build companies that make a lasting impact. We congratulate all honorees on this significant achievement."
Inc. will celebrate the honorees at the 2026 Inc. 5000 Conference & Gala, taking place October 14–16 in Dallas, Texas and the top 500 will be listed in the Fall issue of Inc. Magazine. Tickets are on sale now.
