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.
