Company Overview
About Horizon3.ai
Horizon3.ai is a cybersecurity company founded in 2019 by former US National Security veterans and headquartered in San Francisco. Its flagship product, NodeZero, is an autonomous penetration testing platform that executes real-world attack techniques without agents or disruption — simulating what a sophisticated attacker would do across networks, Active Directory environments, cloud infrastructure, and containerized workloads. NodeZero autonomously discovers and chains vulnerabilities, exfiltrates credentials, and generates remediation guidance, replacing the need for infrequent and expensive manual pentests.
Business Model & Competitive Advantage
The company has achieved significant commercial traction: nearly 4,000 companies worldwide use NodeZero as of 2025 (up 117% YoY), and Horizon3.ai has executed more than 170,000 autonomous pentests — surpassing the collective history of manual pentesting in just a few years. In 1H 2025, the company reported 137% year-over-year ARR growth, with its enterprise segment expanding 485% YoY. In August 2025, NodeZero became the first AI to fully solve the Game of Active Directory (GOAD) benchmark — a respected test of real-world Active Directory exploitation capability — completing it in just 14 minutes.
Competitive Landscape 2025–2026
Horizon3.ai published the 2025 Cybersecurity Insights Report based on findings from more than 50,000 NodeZero pentests, providing industry intelligence on attack paths and vulnerability trends. The platform integrates with security tools like CrowdStrike and Splunk and is used by global governments, Fortune 10 companies, and major healthcare providers. The company also offers NodeZero Kubernetes Pentesting, the only autonomous pentest deployable into a Kubernetes container. Horizon3.ai was named a Sample Vendor in the 2025 Gartner Hype Cycle for Security Operations.
