Horizon3.ai’s NodeZero delivers autonomous penetration testing that finds, exploits, and proves vulnerabilities with evidence your team can act on immediately. (★ 4.7 on G2)
NodeZero runs genuine attack chains autonomously, going beyond vulnerability scanning to demonstrate real impact. It safely exploits discovered weaknesses, chains findings into privilege-escalation paths, and produces proof such as captured hashes or accessed files that confirms severity beyond doubt. The platform is designed for continuous use: organizations schedule assessments against their infrastructure and receive prioritized findings with guided remediation and verified fixes. Because findings are proven rather than theoretical, teams can focus effort on issues that matter. NodeZero covers internal networks, external surfaces, cloud environments, and active directory, and its reporting serves both engineers and compliance auditors. The autonomous model effectively puts offensive security capability on a schedule rather than an annual engagement. The platform’s remediation verification closes the loop: after fixes are applied, NodeZero retests automatically and confirms whether the exposure is truly gone, preventing quietly recurring weaknesses. Reporting templates align with common frameworks, which shortens the evidence-gathering work that compliance reviews otherwise demand.
Horizon3.ai sells NodeZero through enterprise agreements based on assessment scope and frequency; trial engagements let teams run real assessments on production environments before committing. Pricing page not published; contact sales.
Security teams that need offensive testing at continuous frequency, and organizations whose compliance regimes require demonstrated — not just scanned — security validation. It fits lean security teams that cannot staff a red team but cannot accept annual testing as sufficient coverage either. Penetration testing firms also use NodeZero to extend consultant capacity between manual engagements.
