About
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.
