Get to Know Us

Horizon3.ai is an innovative, rapidly growing cybersecurity company on a mission to help organizations proactively identify, fix, and verify exploitable vulnerabilities before they can be leveraged by cybercriminals. Our flagship product, NodeZero™, delivers autonomous pentests and security assessments that scale across complex environments, including internal, external, cloud, and hybrid cloud infrastructures. From small educational institutions to global enterprises, our platform is trusted by a wide range of organizations—IT and SecOps teams, MSSPs, MSPs, and consulting pentesters.

Our team blends former U.S. Special Operations cyber operators, startup engineers, and seasoned cybersecurity professionals. Together, we’re tackling the industry's toughest challenges: ineffective tools, false positives, alert fatigue, skills shortages, and the high costs and long timelines associated with traditional consulting. We are a culture of learn-it-alls—focused on collaboration, respect, ownership, and delivering results.

As a fully remote company, we prioritize flexibility and require a minimum 25Mbps broadband connection.
