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.
Reblaze (Link11) Web Security
-
Private Cloud Deployment
Dedicated virtual private cloud per customer eliminates multi-tenant security concerns and enhances data privacy.
-
Machine Learning Detection
ML-powered traffic analysis automatically identifies and blocks malicious requests while allowing legitimate traffic.
-
Bot Management
Advanced bot detection distinguishing between legitimate users, good bots (search engines), and malicious automation.
-
DDoS Protection
Integrated Link11 DDoS mitigation with global scrubbing network for volumetric and application-layer attacks.
-
API Security
Protection for REST and GraphQL APIs with schema validation and anomaly detection.
-
Managed SOC
24/7 Security Operations Center monitoring with expert incident response and threat hunting.
