-
Declarative Security Policies
WAF policies defined in JSON or YAML, designed for version control and CI/CD integration. Security-as-code approach where policies deploy alongside application code through the same pipelines.
-
API Security
Import OpenAPI/Swagger specifications to automatically enforce API contracts. Schema validation, parameter type checking, and rate limiting for REST, GraphQL, and gRPC APIs. Blocks requests that violate the API specification.
-
ML-Powered DoS Protection
Behavioral analytics using machine learning to detect and mitigate Layer 7 denial-of-service attacks. Learns normal traffic patterns and automatically identifies anomalous request rates, slow POST attacks, and resource exhaustion attempts.
-
Bot Protection
Multi-layered bot detection combining signature matching, anomaly detection, and behavioral analysis. Identifies credential stuffing bots, web scrapers, and automated vulnerability scanners.
-
Kubernetes Ingress WAF
Native WAF support in the NGINX Ingress Controller. Attach WAF policies to specific ingress resources for per-service or per-route security. Policies managed through Kubernetes CRDs and annotations.
-
NGINX One Visual Editor
The NGINX One console provides a GUI-based WAF policy editor, replacing the original CLI-only configuration. Security teams can create, modify, and monitor WAF policies through a web interface without writing JSON.
