Action1 Is America's #1 Fastest-Growing Founder-Led Cybersecurity Company on the Inc. 5000 for the Second Consecutive Year

4,512% three-year revenue growth solidifies Action1's place among the nation's most successful companies

HOUSTON, Aug. 13, 2026 /PRNewswire/ -- Action1, a leading provider of autonomous endpoint management (AEM) solutions, today announced it has been named to the 2026 Inc. 5000, the annual ranking of the fastest-growing companies in America, landing as the #1 fastest-growing founder-led cybersecurity company for the second consecutive year. The recognition underscores Action1's accelerating year-over-year growth and reflects surging demand for its autonomous approach to endpoint security and patch management, which helps thousands of organizations close security gaps before they can be exploited and lead to breaches.

"We started Action1 with a vision of a world where cyberattacks exploiting vulnerabilities are entirely prevented across every device, operating system, and application," said Mike Walters, President and Co-founder of Action1. "Two years running on the Inc. 5000, backed by Action1's 98% customer retention rate, confirm that organizations increasingly rely on us to help get there."

The company's 4,512% three-year revenue growth, driven by rising demand and growing customer trust, signals an industry-wide shift: as organizations retire legacy patch tools, Action1's cloud-native, autonomous patch management platform has become a go-to replacement. It gives enterprise IT and security teams full control over security updates across thousands of endpoints from a single console, without manual work, scripts, or on-premises infrastructure. The first 200 endpoints are free with no functional limits, allowing them to validate the solution against their real environment before scaling up. Remediation gets faster, workloads get lighter, and security gaps close before they become risks.

This year's Inc. 5000 recognizes a new class of companies redefining what growth looks like. These businesses are expanding their impact, creating jobs, and proving that entrepreneurial ambition continues to fuel the U.S. economy.

"Every company on the Inc. 5000 has a story of perseverance, smart decision making, and a refusal to sit still," said 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."
