Agentic Index
Horizon3.ai vs XBOW (2026)
The two best known autonomous pentest platforms, and they are built for different rooms. That verdict is the Agentic Index coverage score, graded from each vendor's own published materials.
Horizon3's NodeZero runs continuously and safely in production with no persistent agents, chaining real attack paths across internal, external, cloud, Active Directory and web app surfaces and verifying fixes instantly, FedRAMP High Authorized. XBOW directs thousands of parallel agents that chain vulnerabilities into reproducible exploit validated paths, first AI to reach number one on HackerOne, from 6,000 dollars per on demand engagement. Horizon3 for continuous internal assurance, XBOW for application depth and a priced entry point.
On the Agentic Index AI SOC ranking, neither Horizon3.ai nor XBOW clears the bar, which asks for all five investigation loop capabilities documented in full. Horizon3.ai does not document human oversight and guardrails in full; XBOW does not document triggers and channel coverage in full, nor human oversight and guardrails. 24 of the 94 vendors in the lane clear it.

This comparison is published by Agentic Index, an independent agentic AI vendor research platform. Horizon3.ai and XBOW are each graded against the same 14 capability Agentic Index taxonomy, from the vendor's own public materials under the Agentic Index verification standard, alongside 969 researched vendors. No vendor pays for placement and no vendor has reviewed this page. How this evidence is graded
Choose Horizon3.ai if
- Internal network, Active Directory and cloud surfaces are the scope, not just applications.
- FedRAMP High Authorization is a procurement requirement your environment imposes.
- Running safely in production with no persistent agents is what makes this deployable for you.
Choose XBOW if
- Application security is the scope and exploit validated proof is what you need to show developers.
- A 6,000 dollar on demand engagement lets you buy one test before buying a program.
- The HackerOne result is the evidence you want against a claim this category makes loosely.
