We are proud to announce that Horizon3.ai has been named a Representative Vendor in the 2025 Gartner® Market Guide for Adversarial Exposure Validation (AEV). Gartner® defines “adversarial exposure validation (AEV) as technologies that deliver consistent, continuous and automated evidence of the feasibility of an attack.” 

At Horizon3.ai, we believe AEV is essential for helping teams shift from identifying vulnerabilities to confirming exploitability in real environments.

NodeZero®: Operationalizing Adversarial Exposure Validation at Scale

According to Gartner®, solutions in the AEV market consist of technology that helps:

  • Optimize defense
  • Improve exposure awareness
  • Scale offensive-testing capabilities

NodeZero was built from the ground up to support these use cases by autonomously executing multistage attack scenarios across hybrid environments. From lateral movement and credential abuse to privilege escalation and impact demonstration, NodeZero validates whether exposures are actually exploitable in real, live environments.

NodeZero: Purpose-Built to Deliver Outcomes That Matter:

  • Test in production – No simulations, real readiness assessments
  • Unlimited testing – Priced per asset, not per test
  • Continuously updated – SaaS delivery ensures the latest attacker TTPs
  • Transparent attack paths – Including proof of exploitation with details
  • One-click retesting – Quickly verify if remediations are effective
