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.
Radware Cloud WAF Service
-
Automatic Policy Generation
Patented technology automatically creates and optimizes security policies for new applications.
-
Positive and Negative Security
Combines signature-based detection with positive security model for comprehensive protection.
-
Bot Manager
Advanced bot detection using behavioral analysis, device fingerprinting, and CAPTCHA challenges.
-
API Protection
Discover and protect APIs with schema validation, rate limiting, and anomaly detection.
-
DDoS Protection
Integrated network and application layer DDoS mitigation backed by Radware''s global scrubbing network.
-
Geo-Fencing
Block or allow traffic based on geographic location with granular country-level controls.
Which One Is Right for You?
The best WAF depends on your specific requirements, infrastructure, and team expertise.
NAXSI
