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.
