API Security

Get deep visibility into your API ecosystem by discovering known and unknown APIs, performing threat modeling, running posture checks via custom rules, and enabling expert-led analysis. Every API is fully documented with method, headers, parameters, auth, and risk metadata — all without requiring runtime agents or traffic proxying.
