Tech Unicorn Horizon3.ai, The Fastest Growing Cyber Company in North America, Strategically Commits to Europe with New Amsterdam Headquarters
New regional hub strengthens Horizon3.ai’s support for customers and partners across Europe, the Middle East and Africa as organisations shift toward continuous security validation
Amsterdam, 26 June 2026 – Horizon3.ai, the AI-native proactive security leader, has opened its new Amsterdam office, which will serve as the company’s EMEA headquarters. The strategic expansion reflects accelerating demand across the region for AI-native proactive security assessment solutions as organisations seek to understand which security weaknesses are truly exploitable and whether their defences can withstand real-world attacker behaviour.
The official opening took place in Amsterdam on 24 June and was attended by Horizon3.ai Co-founder and CEO Snehal Antani, alongside Co-founder Anthony Pillitiere and Keith Poyser, Vice President for EMEA.
The new office will support Horizon3.ai’s rapidly expanding EMEA customer base, channel ecosystem and regional operations. The company is continuing to recruit heavily across the region as enterprises look for more scalable ways to validate cyber resilience, reduce exposure and verify the effectiveness of security controls.
Amsterdam Becomes Horizon3.ai’s EMEA Base
Amsterdam will serve as the central hub for Horizon3.ai’s EMEA operations, supporting customers and partners across key markets. The decision to establish the company’s regional headquarters in the Netherlands was driven by Amsterdam’s world-class talent, digital infrastructure, and international connectivity, making it uniquely positioned for Horizon3.ai’s continued international expansion across Europe, the Middle East, and Africa.
Over the past 12 months, the company’s EMEA team has grown by 283%, with further expansion planned as customer demand continues to accelerate. As organisations across the region face growing pressure from boards, regulators, customers and insurers to demonstrate that their security programmes are effective in practice, not just in policy, Horizon3.ai expects its EMEA headcount to increase by an additional 73% by the end of the year.
“At a time when attackers are moving faster and using AI more effectively, organisations need more than vulnerability scans, dashboards and periodic assessments,” said Keith Poyser, Vice President EMEA at Horizon3.ai. “With our focus on exploitability, our Amsterdam headquarters and fast growing regional team here strengthen our ability to support customers across EMEA as they shift to continuous assurance.”
“Cybersecurity has entered a new phase where confidence alone is not enough,” added Snehal Antani, Co-founder and CEO of Horizon3.ai. “Security teams need the ability to continuously validate their exposure. Our expansion in Amsterdam reflects both the scale of this market transition and our long-term commitment to Europe.”
From Periodic Testing to Continuous Validation
Horizon3.ai’s expansion comes as security teams face growing pressure to prove that cyber investments are reducing real exposure. Traditional approaches such as vulnerability scanning, annual penetration tests and compliance-led assessments often fail to show whether an attacker could still reach critical systems.
NodeZero, the world’s best and most experienced AI Hacker, has autonomously executed more than 250,000 production-safe pentests across enterprise environments. These are real-world assessments across sectors including healthcare, manufacturing, financial services and critical infrastructure, not lab-based exercises.
Unlike traditional tools, NodeZero continuously identifies and links exploitable weaknesses across web applications, network infrastructures, Active Directory, cloud environments, and identity systems, showing how attackers could move through an organization to reach critical systems and sensitive data. This helps expose real-world risks that traditional tools and manual testing approaches can miss.
Building the EMEA Team
Horizon3.ai is continuing to expand its EMEA team across sales, technical, customer success, channel and operational roles. The Amsterdam office will provide a base for regional collaboration, customer engagement and partner enablement as adoption of Horizon3.ai’s AI-native Proactive Security Platform continues to grow.
