What it does
NodeZero runs unlimited autonomous pentests that uncover exploitable attack paths, guide remediation and immediately verify that fixes worked, without installing persistent agents. Horizon3's AI page describes how NodeZero builds a cyber-terrain map of the environment, plans attack paths and makes decisions from what it observes, combining graph reasoning for attack planning, classical ML for classifying files and behaviours, and scoped GenAI for high-value targeting, executive narratives and data-compromise analysis. Use cases include internal, external, cloud, Kubernetes and web-app pentesting, Active Directory password audits, tripwires and rapid response to new CISA KEV exploits. Horizon3 markets a NodeZero Federal offering with FedRAMP High authorisation (vendor claim, not checked against the FedRAMP Marketplace in this run). The About page says Horizon3 is headquartered in San Francisco, CA. Pricing is not published.
