Features Comparison
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.
Palo Alto Networks Prisma Cloud WAAS
-
OWASP Top 10 Protection
Full coverage of OWASP Top 10 vulnerabilities including SQL injection, XSS, and code injection.
-
API Discovery & Protection
Automatic API discovery with ML-based profiling and OpenAPI/Swagger spec enforcement.
-
Bot Risk Management
Detect and manage web bots with customizable policies for different bot categories.
-
DoS Protection
Application-layer DoS protection with rate limiting and traffic analysis.
-
Agentless Deployment
Deploy protection without agents for simplified operations in cloud environments.
-
Virtual Patching
Immediate protection against known CVEs while permanent fixes are developed.
Which One Is Right for You?
The best WAF depends on your specific requirements, infrastructure, and team expertise.
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
Palo Alto Networks Prisma Cloud WAAS
- You need: Large enterprises, multi-cloud deployments, organizations using Prisma Cloud, cloud-native application teams
- You're using: AWS, Azure, GCP, Kubernetes, Docker, OpenShift, any cloud-native environment
We recommend evaluating both options with a trial or free tier before committing. Consider your existing infrastructure, team expertise, compliance requirements, and budget.
