Horizon3.ai’s NodeZero is an autonomous penetration testing platform that continuously attacks your environment to reveal what’s truly exploitable. It traverses internal, external, cloud, Active Directory, and Kubernetes assets, chaining exposures into realistic attack paths that highlight business impact. Tests are production‑safe and fully automated, enabling frequent pentests without the cost and scheduling pain of traditional consulting. NodeZero outputs prioritized findings with remediation guidance and supports CTEM, security control validation, zero‑/N‑day exposure checks, third‑party risk, and compliance‑driven testing.
