Features Comparison
Barracuda Web Application Firewall
-
Advanced Bot Protection
Machine learning-powered detection distinguishes malicious bots from legitimate traffic and good bots.
-
API Discovery & Protection
Automatically discover APIs and generate security rules from OpenAPI definition files.
-
JSON & XML Security
Deep inspection of JSON payloads and XML protection against schema poisoning attacks.
-
SSL/TLS Offloading
Hardware-accelerated SSL termination with support for modern TLS protocols and cipher suites.
-
DevOps Integration
Full REST API with OpenAPI spec and native support for IaC tools like Terraform and Ansible.
-
Active Directory Integration
Integrate with AD, LDAP, RADIUS for authentication with SAML SSO and two-factor authentication support.
NAXSI
-
Scoring-Based Detection
Assigns scores to suspicious patterns in requests. Blocks when the cumulative score exceeds a threshold, rather than relying on exact signature matches.
-
Learning Mode
Monitors traffic and automatically generates whitelist rules for legitimate application behavior, reducing manual tuning effort during initial deployment.
-
Virtual Patching
Apply custom rules to block specific vulnerabilities without modifying application code. Rules target raw requests or specific fields like headers, args, and body.
-
Deny-by-Default
Operates like a DROP firewall. Common attack characters and patterns are blocked unless explicitly whitelisted for the target application.
-
Lightweight Footprint
Written in C with only libpcre as a dependency. Adds minimal overhead to NGINX request processing.
-
Dynamic Module Support
Can be compiled as a dynamic NGINX module, allowing it to be loaded without recompiling NGINX from source.
Which One Is Right for You?
The best WAF depends on your specific requirements, infrastructure, and team expertise.
Barracuda Web Application Firewall
- You need: Mid-market organizations, DevOps teams, hybrid deployments, organizations needing on-premises WAF options
- You're using: Any web application, AWS, Azure, GCP, VMware, Hyper-V, on-premises
NAXSI
- You need: Teams already running NGINX who want lightweight inline WAF protection, budget-conscious deployments, applications with predictable request patterns, virtual patching use cases
- You want to start with a free tier
- You prefer open-source solutions
- You're using: NGINX, Linux (Debian, Ubuntu, CentOS), FreeBSD, OpenBSD, NetBSD, Docker
We recommend evaluating both options with a trial or free tier before committing. Consider your existing infrastructure, team expertise, compliance requirements, and budget.
