ModSecurity Integration
Built-in ModSecurity WAF with OWASP Core Rule Set for comprehensive protection against web application attacks.
-
Bot Protection
Block malicious bots with challenge-based verification using cookies, JavaScript tests, captchas, or third-party services.
-
Rate Limiting & DDoS Protection
Limit connections and requests from clients, automatically ban suspicious activities triggering abnormal HTTP status codes.
-
IP Reputation

-
Web UI Management
User-friendly graphical interface for configuration and monitoring without command-line expertise.
-
Plugin System

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.
