CrowdSec Web Application Firewall

• Crowd-Sourced Threat Intelligence

  Network of 200,000+ installations sharing attack signals in real-time. Blocks malicious IPs 7-60 days before other vendors detect them.

• ModSecurity Rule Compatibility

  Load existing ModSecurity SecLang rules directly. Teams migrating from ModSecurity can reuse their rule sets without rewriting.

• Virtual Patching

  Block exploitation attempts at the WAF layer before application patches are deployed. Protect against known CVEs without code changes.

• Advanced Behavior Detection

  Goes beyond single-request analysis. Generates internal events to build complex multi-request scenarios before triggering blocks.

• Proxy Integration

  Native integration with Nginx, Traefik, HAProxy, Apache, and Envoy. No separate appliance needed.

• Kubernetes Ready

  Runs as a sidecar or within ingress controllers. Fits containerized and microservice architectures.

• Console Dashboard

  Web-based management console for monitoring alerts, managing blocklists, and configuring the security engine.

• Community Blocklists

  Free access to crowd-sourced IP blocklists updated in real-time from the CrowdSec network.

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.
