Horizon 3

Horizon3.ai delivers the NodeZero Autonomous Security Platform, a solution designed for continuous, automated penetration testing. This platform actively identifies exploitable attack paths across various environments, including internal networks, external perimeters, cloud infrastructure, Kubernetes deployments, and Active Directory configurations. NodeZero’s approach allows organizations to proactively discover and remediate vulnerabilities, continuously verifying their security posture against evolving threats without manual intervention.

The company was founded in 2019 by Snehal Antani and Anthony Pillitiere. Their foundational insight stemmed from the collective experience of former US Special Operations cyber operators and seasoned cybersecurity professionals who recognized the limitations of traditional security assessments. This led them to develop a method for dynamic, adversary-centric testing that transcends conventional vulnerability scanning, addressing gaps in existing security practices.

NodeZero serves a diverse clientele, including IT operations, security operations teams, and professional pentesters across industries such as federal, financial services, and healthcare. Horizon3.ai's long-term vision is to empower organizations with an always-on, proactive security defense, enabling them to discover and eliminate exploitable weaknesses before they can be leveraged by malicious actors.
