open-appsec
-
ML-Based Detection
Pre-trained machine learning engine detects threats based on context and intent, not signatures. No rule tuning required.
-
Automatic Learning
Continuously learns application-specific traffic patterns in production, reducing false positives over time without manual intervention.
-
Native Proxy Integration
Runs as a module inside NGINX, Kong, or Envoy rather than as a separate proxy, eliminating additional network hops and latency.
-
Kubernetes Ingress
Functions as a Kubernetes Ingress Controller with built-in WAF, providing security at the ingress layer without sidecars or service mesh.
-
API Protection
Protects REST APIs against OWASP API Top 10 threats using the same ML engine, with automatic API discovery and schema enforcement.
-
Anti-Bot
