The NodeZero™ platform empowers organizations to continuously find, fix, and verify exploitable attack surfaces. It is the flagship product of Horizon3.ai, founded in 2019 by former industry and U.S. National Security veterans. Our mission is to help organizations see their networks through the eyes of the attacker and proactively fix problems that truly matter, improve the effectiveness of their security initiatives, and ensure that they are prepared to respond to real cyberattacks.

Reduce your security risk by autonomously finding weaknesses in your network, knowing how to prioritize and fix them, and immediately verifying that your fixes work. NodeZero delivers production-safe autonomous pentests and other key assessment operations that scale across your largest internal, external, cloud, and hybrid cloud environments. No required agents, no code to write, and no consultants to hire.
