“This recognition underscores the fundamental shift underway in how enterprises are executing on their Zero Trust journey. Organizations are decisively moving past legacy network-centric platforms and traditional NAC, embracing identity-driven microsegmentation that spans IT, IoT, OT, and hybrid environments. Our customers aren’t willing to wait years rearchitecting their networks to protect their most critical assets, they’re deploying Elisity in weeks, with no disruption, and gaining immediate, real-time visibility and policy control over every user, device, and workload,” said James Winebrenner, CEO, Elisity. “As threat actors increasingly exploit vulnerable identities and devices and rely on rapid lateral movement, enterprises need segmentation that is dynamic, automated, and rooted in identity, not constrained by brittle network constructs. Elisity was built for this new reality, and this milestone reflects the trust each of our customers places in our approach.”

Microsegmentation is now a priority for modern cybersecurity postures to stop lateral movement in networks. Still, legacy hardware and agent-centric approaches cannot keep up with environments spanning IT, IoT, and OT. Identity-based microsegmentation maps least-privilege policy to the entity itself, including users, devices, applications, and workloads, and evaluates dynamic identity context rather than static network topology. By continuously understanding who and what are communicating and automatically enforcing least-privilege access, organizations can secure unmanaged and mission-critical OT systems, contain threats in real time, and adopt Zero Trust without rearchitecting networks or interrupting operations. Elisity enables enterprises to move from broad trust zones to fine-grained identity-driven controls in weeks, not years, delivering practical Zero Trust segmentation with visibility, automation, and scale.

“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. As in previous years, private companies continue to dominate, underscoring the agility that private enterprises bring to competitive markets, enabling the exceptional triple and quadruple digit growth reflected in these rankings.”

Overall, 2025 Technology Fast 500 companies achieved revenue growth ranging from 122% to 29,738% over the three-year time frame, with an average growth rate of 1,079%.

Over the past twelve months, Elisity has achieved significant milestones across product, market, and recognition fronts. The company was named a Cool Vendor™ in the Gartner® Cool Vendors™ in Cyber-Physical Systems Security 2025. It earned the Overall Network Security Solution Provider of the Year award in the CyberSecurity Breakthrough Awards. It was also recognized as a Sample Vendor in the Gartner® Hype Cycle for Enterprise Networking 2025 and as a Representative Vendor in the 2025 Market Guide for Network Security Microsegmentation. With this recognition, Elisity has also expanded its customer base into major regulated sectors (including healthcare, manufacturing, and critical infrastructure), accelerated its go-to-market through new partner engagements, and reported that more than 83% of its enterprise customers achieved full segmentation roll-out within 90 days.
