We are excited to share that Action1 ranked #4 fastest-growing cybersecurity company, #9 in the Software & Services industry, and #16 overall on the 2025 Deloitte Technology Fast 500™ among the fastest-growing tech companies in North America.
Across all 500 recognized organizations in technology, media, telecommunications, life sciences, fintech, and energy tech, the average three-year growth rate reached 1,079%. Action1 didn’t just meet this benchmark—we exceeded it sevenfold, achieving a remarkable 7,265% revenue increase from 2021 to 2024. This reaffirms that our autonomous endpoint management and patching platform stands out as one of the most dynamic SaaS solutions driving transformation in IT security and operations.
This momentum is not a one-time spike but reflects a consistent growth trajectory, with 327% year-over-year growth and a 205% increase in the customer base in 2024, while maintaining a 99% gross retention rate. However, these impressive numbers tell only part of the story. What truly matters is what’s behind them, and that’s customers choosing Action1 to protect their most critical assets. This drives our continued platform adoption, as we earn long-term customer trust by delivering the solutions that companies of all sizes need to secure what they’ve built.
“The recognition from Deloitte is a testament to the dedication of Action1’s global team, united by a bold vision—to prevent cyberattacks that exploit vulnerabilities across every device, operating system, and application,” said Alex Vovk, CEO and co-founder of Action1. “Building on this momentum, Action1 will continue to expand its platform capabilities and global presence to empower more IT and security teams with smarter, autonomous patching and endpoint management.”
What Makes This Achievement Significant
The Deloitte Technology Fast 500™ is a prestigious annual ranking that doesn’t hand out participation trophies. Instead, it recognizes real growth.
To qualify, companies must own proprietary intellectual property or technology that contributes to operating revenues, maintain base-year operating revenues of at least $50,000 and current-year operating revenues of at least $5 million, demonstrate growth of 50% or greater, operate for a minimum of four years, and be headquartered within North America.
“This year’s rankings highlight both enduring leadership and breakthrough momentum,” said Wolfe Tone, US Deloitte Private & Emerging Client Portfolio leader and partner, Deloitte Tax LLP. “More than half of the winners are prior honorees, yet the majority of the top ten are first-time entrants—demonstrating the staying power of established leaders alongside the accelerating growth of new innovators across key sectors.”
Action1 earned recognition in the most competitive category on the list. Software & Services companies have consistently dominated this ranking for nearly thirty years, which makes reaching #9 really meaningful for our team. It reflects years of work, testing, improvement, and the kind of persistence that rarely shows up in the numbers alone.
What Action1 Actually Does
Cyberattacks have become one of the leading causes of business shutdowns. A single exploited vulnerability can put you out of business. Action1 minimizes these risks by replacing traditional patch management tools that require on-premises infrastructure, manual workflows, and constant oversight.
These tools were built for a time when IT infrastructures were far simpler, attack surfaces were manageable, and IT teams weren’t overwhelmed by patch volumes. Those days are long gone, and none of those assumptions hold true anymore.
Action1 perfectly fulfills the demands of modern SMBs, large enterprises, and MSPs by delivering a cloud-native, scalable, autonomous endpoint management platform. It needs no servers to maintain, no VPN requirements, and no time wasted on manual processes. The outcome? Patching that just works.
The software uses risk-based prioritization that surfaces vulnerabilities in real-time and automates update/patch deployments across Windows, macOS, Linux, ARM-based systems, and third-party applications. With it, your IT team saves time, manpower, and hardware resources while minimizing your endpoints’ attack surface within hours or days instead of weeks. Better yet, compliance reporting becomes audit-ready in just a few clicks.
Simply put, Action1 delivers end-to-end automation that makes patch management a set-it-and-forget-it process, allowing you and your team to focus on business growth and improving the quality of your services. Whether endpoints are on-premises or remote, you can manage and secure them all directly in your browser, from anywhere, anytime, with no added complexity.
