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.
Horizon3.ai is a security company focused on attacker-validated risk: proving what’s actually exploitable so teams can fix the right things first and then re-check that the fix worked. Its NodeZero platform is used for continuous exposure assessment across on-prem and cloud environments, and it’s extended with products like Tripwires (decoy-based signals to surface suspicious behavior early), Vulnerability Risk Intelligence (adds exploit evidence and context to scanner findings from tools like Tenable/Qualys/Rapid7), and Rapid Response testing for newly disclosed or actively exploited CVEs, including items in the CISA KEV catalog.
