Horizon3.ai, the leading provider of offensive security solutions, today announced that it has been named to the Silicon Valley Defense Group’s NatSec100 list for the second consecutive year. The NatSec100 recognizes the top venture-backed dual-use and national security companies demonstrating significant growth momentum and mission relevance across the national security ecosystem.
The NatSec100 highlights organizations driving impact across defense, critical infrastructure, intelligence, space, cyber, and advanced manufacturing. Horizon3.ai appears alongside some of the most innovative companies working to strengthen the National Security Innovation Base and expand the supply of field-ready capabilities.
Horizon3.ai joins a cohort of NatSec100 companies that span the full breadth of modern national-security innovation, including AI-driven readiness platforms, advanced materials and manufacturing, dual-use energy and infrastructure technologies, resilient supply-chain solutions, and next-generation cyber and space systems. This broad representation underscores how the NodeZero® Offensive Security Platform contributes to national resilience by helping organizations identify and fix exploitable security weaknesses before adversaries can act.
Horizon3.ai’s role in supporting the NSA Cybersecurity Collaboration Center’s CAPT program, powered by NodeZero, reflects the company’s commitment to strengthening the security posture of defense organizations that play a critical role in national resilience. CISA’s OCIO also uses NodeZero to secure their infrastructure, and leverages the platform to deliver vulnerability-assessment services to Federal Civilian Executive Branch (FCEB) agencies, Tribal Nations, and critical infrastructure providers as part of its national-mission support.
“Our mission is to help defenders stay ahead of real adversaries by thinking like attackers. Being included again in the NatSec100 shows the impact our technology is having as organizations focus on what is actually exploitable across their environments. The key point is that speed and verification matter,” said Snehal Antani, CEO and Co-Founder, Horizon3.ai. “The future of national security depends on the ability to move fast, validate what matters, and operationalize results, and that is exactly what our customers are doing with NodeZero at scale.”
Horizon3.ai’s NodeZero is used by leading enterprises, critical infrastructure operators, and defense organizations to find, fix, and verify exploitable vulnerabilities across on-premises, cloud, and hybrid environments. By performing real attacks and validating their impact without causing disruption, NodeZero helps organizations strengthen their defenses by focusing remediation on weaknesses that truly matter.
