Horizon3.ai

Horizon3.ai is a cybersecurity company whose NodeZero platform delivers autonomous penetration testing and continuous security posture management. NodeZero safely attacks your internal, external, cloud, and hybrid environments the way a real adversary would, proving exploitable attack paths, prioritizing the fixes that matter, and verifying that remediations actually work. Horizon3.ai exposes a publicly documented GraphQL API (the NodeZero API) plus an h3-cli command-line tool and a hosted Model Context Protocol (MCP) server, letting teams schedule pentests, retrieve findings, weaknesses, attack paths, credentials, and host inventory, and wire results into CI/CD, ticketing (Jira, ServiceNow), and agentic workflows. NodeZero Federal is FedRAMP High authorized for public-sector use.

Kin Score

This is the API Evangelist rating — a single, repeatable read computed from the artifacts on this page. Green fill is points earned; the red track is points possible, so every bar shows earned-versus-possible at a glance.

How we profile Horizon3.ai

Each block below is one kind of artifact we hold for Horizon3.ai. For each we say what it is and why it earns a place in the profile, then list every one we've indexed — capped at two rows, scroll within the panel for the rest.

APIs 1

Each API is captured as its own OpenAPI definition — every operation, parameter, and response. This is the single most useful machine-readable description of what an API does, and it's what lets us score, lint, mock, and generate against it without asking the provider for anything.

Individual APIs this provider publishes, each with its own machine-readable definition.

NodeZero GraphQL API

The NodeZero API is a publicly accessible GraphQL API that exposes a subset of the Horizon3.ai Portal: schedule and control autonomous pentest operations, and read pentests, ops...

MCP Servers 1

Model Context Protocol servers expose these APIs directly to AI agents. We profile them because agent-native access is the fastest-growing way this provider's capabilities actually get used.

Event Specifications 1

Not every API is request/response. AsyncAPI describes the event-driven and streaming side — the webhooks and channels — so the asynchronous half of the interface is documented the same way the synchronous half is.

Security Posture 4

Authentication, domain security, vulnerability disclosure, and trust-center signals — the evidence that a provider takes security seriously enough to document it. We profile it because you can't govern what you can't see.
