Features Comparison

Bunny Shield

  • AI-Powered WAF

    Next-gen WAF engine that blocks zero-day exploits, OWASP Top 10, and emerging risks with AI recommendations and real-time logs.

  • DDoS Protection

    Volumetric and application-layer DDoS mitigation backed by 250+ Tbps network capacity across 119 global scrubbing centers.

  • Global Rate Limiting

    Set precise rate limits per IP, user, or path globally across your entire infrastructure to control abuse.

  • Bot Mitigation

    Detect, block, and neutralize malicious bots in real time using behavioral fingerprinting without impacting legitimate users.

  • Access Lists

    Block traffic using curated threat lists for VPNs, Tor nodes, and other threat sources, or create custom access controls.

  • Upload Scanning

    Automatically scan uploaded files for viruses, malware, and CSAM to prevent harmful content from reaching your platform.

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.
