Features Comparison
CDNetworks Application Shield
-
Edge-Based WAF
WAF filtering at 1,500+ global edge locations for low-latency protection close to end users.
-
DDoS Protection
Multi-layer DDoS mitigation covering network (L3/L4) and application (L7) layer attacks.
-
Bot Management
Identify and manage automated traffic including scrapers, credential stuffers, and inventory hoarders.
-
API Protection
Secure APIs against abuse, injection attacks, and unauthorized access with dedicated API security rules.
-
Virtual Patching
Quickly mitigate known vulnerabilities without modifying application code.
-
Real-Time Analytics
Comprehensive dashboards showing attack trends, blocked requests, and traffic patterns.
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.
CDNetworks Application Shield
- You need: Businesses with significant Asian traffic, organizations needing combined CDN and WAF, enterprises targeting China market
- You're using: Any web application, cloud-hosted sites, on-premises origins
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.
