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.

Nexusguard Application Protection

  • DDoS Threat Intelligence

    Proprietary threat intelligence from monitoring global DDoS attack patterns.

  • CSP Protection

    Specialized solutions for communications service providers.
