About Us

Horizon3 is a fast‑growing cybersecurity company on a mission to help organizations proactively find, fix, and verify exploitable attack vectors before adversaries exploit them. Our flagship platform, NodeZero™, delivers production‑safe autonomous pentesting and attacker‑centric validation across internal, external, cloud, and hybrid environments.

We are a fusion of former U.S. Special Operations cyber operators, startup engineers, and cybersecurity practitioners who were tired of ineffective tools, alert fatigue, blind spots, and “checkbox security.” We operate with a culture of respect, collaboration, ownership, and results, and we’re looking for sellers who thrive in fast‑moving, high‑growth environments.
