Features Comparison
AWS Web Application Firewall
-
AWS Managed Rules
Pre-configured rule groups maintained by AWS and AWS Marketplace sellers for common threats.
-
Custom Rules
Build your own rules using conditions like IP addresses, HTTP headers, URI strings, and more.
-
Rate-Based Rules
Automatically block IPs that exceed defined request thresholds.
-
Bot Control
Managed rule group for detecting and managing bot traffic (additional cost).
-
Fraud Control

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.
Which One Is Right for You?
The best WAF depends on your specific requirements, infrastructure, and team expertise.
AWS Web Application Firewall
- You need: AWS-native applications, organizations already invested in AWS ecosystem, variable traffic workloads, multi-account AWS environments
- You're using: AWS CloudFront, ALB, API Gateway, AppSync, Cognito, App Runner, Verified Access
F5 WAF for NGINX
- You need: Organizations already running NGINX Plus, Kubernetes deployments using NGINX Ingress Controller, DevOps teams wanting WAF-as-code in CI/CD pipelines, microservice architectures needing per-service WAF policies, teams wanting F5 security without BIG-IP complexity
- You're using: NGINX Plus (Linux), NGINX Ingress Controller (Kubernetes), Docker, AWS, Azure (native NGINXaaS), GCP, any NGINX Plus-supported environment
We recommend evaluating both options with a trial or free tier before committing. Consider your existing infrastructure, team expertise, compliance requirements, and budget.
