Features Comparison
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.
open-appsec
-
ML-Based Detection
Pre-trained machine learning engine detects threats based on context and intent, not signatures. No rule tuning required.
-
Automatic Learning
Continuously learns application-specific traffic patterns in production, reducing false positives over time without manual intervention.
-
Native Proxy Integration
Runs as a module inside NGINX, Kong, or Envoy rather than as a separate proxy, eliminating additional network hops and latency.
-
Kubernetes Ingress
Functions as a Kubernetes Ingress Controller with built-in WAF, providing security at the ingress layer without sidecars or service mesh.
-
API Protection
Protects REST APIs against OWASP API Top 10 threats using the same ML engine, with automatic API discovery and schema enforcement.
-
Anti-Bot
Detects and mitigates automated attacks, credential stuffing, and web scraping using behavioral analysis.
Which One Is Right for You?
The best WAF depends on your specific requirements, infrastructure, and team expertise.
HAProxy Enterprise WAF
- You need: High-traffic applications already using HAProxy for load balancing, organizations wanting integrated WAF and load balancing without separate appliances, teams that prioritize low latency and accuracy over rule customization, enterprises running multi-cloud or hybrid deployments
- You're using: Linux (RHEL, Ubuntu, Debian, CentOS, Amazon Linux), Docker, Kubernetes, AWS, Azure, GCP, FreeBSD, virtual appliance
open-appsec
- You need: Kubernetes environments, teams using NGINX or Kong, organizations wanting hands-off WAF protection, cloud-native applications, DevOps teams that do not want to manage WAF rules
- You want to start with a free tier
- You prefer open-source solutions
- You're using: Docker, Kubernetes, Linux, NGINX, Kong Gateway, Envoy
We recommend evaluating both options with a trial or free tier before committing. Consider your existing infrastructure, team expertise, compliance requirements, and budget.
Frequently Asked Questions
Which is better for startups: HAProxy Enterprise WAF or open-appsec?
open-appsec offers a free tier while HAProxy Enterprise WAF does not, making open-appsec more accessible for budget-conscious startups. open-appsec scores higher for ease of use (4.3/5), which is valuable for smaller teams. Consider your immediate security needs and growth plans when choosing.
Which has better support: HAProxy Enterprise WAF or open-appsec?
