Horizon3.ai, the AI-native proactive security leader in, today announced the appointment of Matthew Schaner as Vice President of Sales, Americas. A seasoned technology sales executive, Schaner will lead Horizon3.ai’s commercial teams across the U.S., Canada, and Latin America. In this role, he will accelerate NodeZero’s market penetration, deepen the partner ecosystem, and cultivate the region’s next generation of sales leadership.

With nearly 20 years of sales leadership experience, Schaner specializes in building high-performance teams and go-to-market strategies from the ground up. His background includes leading Netskope’s East Coast Enterprise business through rapid growth, serving as an early regional and practice leader at Zscaler, and spending nine years at Cisco Meraki, where he expanded the NY Public Sector business sevenfold.

“Matthew knows how to turn hyper-growth momentum into market dominance,” said Matt Hartley, Chief Revenue Officer at Horizon3.ai. “He has spent his career building high-performance sales teams and deep partner ecosystems from the ground up. Beyond his leadership, Matthew’s technical depth earns him instant credibility with customers and sellers alike—he understands the problem before solving it. He is the perfect fit to scale Horizon3 across the Americas.”

Horizon3.ai’s NodeZero® Offensive Security Platform enables organizations to continuously identify and remediate exploitable vulnerabilities before attackers can exploit them, driving continuous exposure management across production infrastructure. NodeZero provides customers with the necessary tools to stay ahead of a rapidly evolving threat landscape with autonomous pentesting, emerging threat intelligence, threat detection, and unified data and reporting.

“Horizon3.ai has built a genuinely differentiated platform that proves what is actually exploitable, not just what is theoretically vulnerable, putting the power of autonomous pentesting in the hands of organizations of every size,” said Matthew Schaner, Vice President of Sales, Americas at Horizon3.ai. “There’s an enormous opportunity in front of us across SMB, Mid-Enterprise, and Enterprise, and I am committed to building the teams and ecosystems needed to make NodeZero the standard for offensive security across the Americas.”

Schaner’s appointment builds upon the company’s momentum following last year’s Series D funding round and a series of strategic leadership hires. As the company expands its platform expansion and global go-to-market efforts, Schaner will play a key role in driving the next phase of growth and leadership in autonomous security.
