Top 3 Horizon AI Features
Executes real attacks against live production environments without human involvement. Covers internal, external, cloud, and hybrid environments. No persistent agents required.
Find-Fix-Verify Loop Node Zero identifies exploitable vulnerabilities, provides prioritized remediation guidance, and allows immediate re-testing to confirm fixes are effective — closing the loop without engaging a separate pentest team.
Continuous Threat Intelligence / Rapid Response Monitors for emerging CVEs and zero/N-day vulnerabilities, alerts organizations to risks relevant to their previously scanned environment, and enables targeted testing before attackers can exploit new findings.
What’s In It for You
Risk Reduction
Finds and proves exploitable attack paths before real attackers do — not theoretical vulnerabilities, but confirmed, weaponized ones.
Cost Avoidance
Replaces or reduces reliance on expensive manual pentests. NodeZero claims $6.78M annual cost avoidance per organization by replacing traditional pentests and reducing scanner overhead.
Operational Efficiency
Security teams focus on what actually matters — NodeZero prioritizes by exploitability, not severity score. Reduces alert noise.
Continuous Assurance
One-time penetration tests go stale immediately; NodeZero runs continuously as environments change, giving an up-to-date security posture rather than a point-in-time snapshot.
