Welcome

Welcome to NAT

NAT (Neural Autonomous Tester) is an AI-powered API security testing platform. It autonomously discovers vulnerabilities in your REST and GraphQL APIs — going beyond traditional scanners by using intelligent agents that adapt to your application's behavior in real time.

What is NAT?

NAT combines multi-agent AI with deep API understanding to deliver security testing that is:

  • Autonomous — NAT runs scans end-to-end without manual configuration for each endpoint
  • Intelligent — Adaptive agents prioritize high-risk endpoints and re-test based on new findings
  • Comprehensive — Covers OWASP API Top 10, auth flaws, injection attacks, business logic issues, and more
  • Integrable — Works inside CI/CD pipelines, Docker environments, and on-demand via CLI or REST API

Self-HostedDeploy on your own infrastructure — no data leaves your network
DashboardReal-time scan results, risk scoring, and remediation guidance
Demo ModeSafe, risk-free exploration of all features against a built-in target API

How it works

NAT deploys a team of specialized AI agents that coordinate to:

  1. Discover — Map all endpoints, parameters, and authentication flows in your API
  2. Prioritize — Score endpoints by risk and focus effort on the highest-value targets
  3. Test — Generate and execute intelligent test cases covering known and novel attack vectors
  4. Learn — Adapt strategy based on responses, chaining discoveries into deeper exploit paths
  5. Report — Produce actionable, developer-friendly reports with severity ratings and fix guidance

Get started

The fastest way to try NAT is demo mode — a fully sandboxed environment that runs against a built-in example API with no external dependencies:

pip install nat-engine
nat demo

See the Demo Mode guide for a full walkthrough, or jump straight to Installation to set up against your own API.
