Everything works together — or stands alone
Security testing, an AI co-pilot, and compliance evidence — three pillars that work independently or as an integrated testing lifecycle.
OWASP API Top 10 + GraphQL
All 10 OWASP API checks plus 5 GraphQL-specific security checks — broken auth, excessive data exposure, SSRF, injection, and more.
Autonomous BDI Agents
Multi-agent engine with adaptive risk scoring — agents collaborate, share beliefs, and route to highest-risk endpoints first.
REST + GraphQL + Postman
OpenAPI/Swagger parsing, GraphQL introspection, and Postman Collection v2.1 import — no manual test authoring required.
Extensible Plugin System
Write custom security checks as Python plugins. Load via CLI flags, entry points, or the Python API — extend NAT for your organization's needs.
AI Test Planning & Generation
nat ai plan analyzes your spec and prioritizes by risk. nat ai generate-tests creates targeted test cases — happy path, negative, security, fuzzing.
AI Scan Interpretation
nat ai explain translates findings into plain English with compliance impact. nat ai configure troubleshoots your setup interactively.
Dashboard AI Chat
Floating chat widget in the dashboard with streaming responses. Context-aware — knows your current scan, page, and findings.
Proactive Scan Insights
AI-generated insight cards after every scan: new findings, resolved issues, compliance changes, coverage gaps — with suggested next actions.
Compliance Reports & Audit Trail
AI-generated compliance narratives for OWASP, PCI-DSS, HIPAA, and SOC 2. Full BGSTM 6-phase audit trail with timestamped evidence.
Compliance Badges
Embeddable shields.io badges for your README: OWASP API Top 10 9/10, PCI-DSS 7/8. Auto-updated after every scan.
CI/CD & GitHub Integration
GitHub Action with SARIF upload to Code Scanning, PR comments with scan summaries, quality gates, and configurable severity thresholds.
Zero-Config Onboarding
nat init detects your framework, generates .natrc, and sets up CI. nat status shows health. nat scan --watch gives live progress. nat scan --diff shows regression delta.
Six phases. One command to start.
NAT follows the BGSTM methodology — use one step or all six. The AI co-pilot helps at every phase.
Plan
AI analyzes your spec, identifies high-risk endpoints, and generates a prioritized test plan. Or skip this — just point and scan.
nat ai plan --spec openapi.yamlGenerate
AI creates intelligent test cases: happy path, negative, security, and fuzzing — tailored to each endpoint's risk profile.
nat ai generate-tests --endpoint "POST /payments"Prepare
Zero-config setup detects your framework, generates .natrc, configures auth, and sets up CI. One command.
nat init → Detected FastAPI, created .natrcExecute
Autonomous BDI agents run tests in parallel with real-time progress. Watch findings appear live as agents explore your API.
nat scan --watch --spec openapi.yamlAnalyze
AI interprets findings in plain English, shows regression delta from previous scans, and evaluates compliance impact.
nat ai explain --scan-id abc123 --diff lastReport
SARIF to GitHub Code Scanning, PR comments, compliance narratives, BGSTM audit trail, and embeddable badges — all automatic.
nat ai compliance-report --framework pci-dssUse one step or all six. NAT meets you where you are.
Start scanning in 5 minutes — no install required
The SaaS path gives your team full NAT capability without provisioning a single server. Sign up, paste a URL, and get actionable security findings before your next stand-up.
Sign up — free
Create your account at app.nat-testing.io. No credit card required. Your free tier includes 50 scans per month.
Paste your API URL or spec
Enter your live API URL or upload an OpenAPI / GraphQL spec. NAT reads your spec automatically — no test authoring, no configuration.
See prioritised results
Within minutes, your dashboard shows endpoint risk scores, OWASP findings, and agent-driven insights — sorted by severity, ready to act on.
Prefer self-hosted? pip install nat-engine and run locally — free forever under AGPL-3.0.
Designed for security engineers
A dark-mode dashboard built for fast triage — not checkbox compliance. Every finding links to evidence, not guesswork.
Agent Activity
Real-time belief state visualization for every BDI agent in the scan fleet.
Security Findings
Prioritised OWASP findings with severity, endpoint, and fix recommendations.
Finding Detail
Full request/response traces, CWE references, and remediation guidance.
How NAT compares
Built for the security engineer who needs more than manual test scripts and checkbox scanners.
