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.

HAProxy Enterprise WAF

• Intelligent WAF Engine

  Machine learning-powered threat detection trained on 60+ billion daily requests. Detects zero-day and polymorphic attacks without relying on static signatures. 98.5% balanced accuracy in open source benchmarks.

• OWASP CRS Compatibility

  Optional mode that runs OWASP Core Rule Set rules through the Intelligent WAF Engine, dramatically reducing latency and false positive rates compared to traditional CRS processing.

• WAF Profiles

  Customizable security profiles per application, allowing fine-tuned policies based on each app's unique traffic patterns. Minimizes false positives and alert fatigue for diverse application portfolios.

• Bot Management

  Proprietary bot detection module with 100% local processing for low latency. Identifies and manages automated traffic using fingerprinting and behavioral analysis.

• Global Rate Limiting

  Dynamic, cluster-wide rate limiting powered by the Global Profiling Engine. Tracks and enforces rate limits in real-time across distributed deployments.

• HAProxy Fusion Control Plane

  Centralized management, monitoring, and automation of WAF policies across multi-cluster, multi-cloud, and multi-team deployments from a single dashboard.

• DDoS Protection

  Full-spectrum DDoS mitigation via HAProxy Edge, protecting against volumetric, protocol, and application-layer attacks.

• In-Process Architecture

  WAF runs in the same process as HAProxy, adding virtually zero latency and CPU overhead. No separate WAF appliance or proxy hop required.

• Threat Intelligence

  Real-time threat intelligence from HAProxy Edge's global network, continuously updating the ML models that power the WAF engine.
