F5 WAF for NGINX

7,800+ Attack Signatures
F5's comprehensive threat signature database with continuous updates from F5's threat research team. Covers OWASP Top 10, CVE-specific signatures, and application-specific attack patterns.
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.
Request and Response Inspection
Inspects both incoming requests and outgoing responses. Response inspection catches data leakage, error messages that reveal application internals, and sensitive data exposure.
