Features Comparison
BitNinja Server Security
-
WAF 2.0
Caddy-based reverse proxy WAF with per-domain customizable protection levels and CMS-specific rulesets for WordPress, Joomla, and Drupal.
-
AI Malware Scanner
AI-powered file scanner that detects and removes malware, backdoors, and infected files on the server.
-
IP Reputation Network
Global threat intelligence network that shares IP reputation data across all BitNinja installations in real-time.
-
DDoS Protection
Kernel-level DoS detection that auto-blacklists IPs exceeding connection thresholds.
-
Brute-Force Prevention
Protects SSH, FTP, cPanel, WordPress, and other login endpoints from brute-force attacks.
-
Outbound WAF
Scans outgoing connections from the server to detect compromised sites sending spam or attack traffic.
-
Port Scan Detection
Honeypot system that detects port scanning attempts and globally blacklists scanning IPs.
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.
Which One Is Right for You?
The best WAF depends on your specific requirements, infrastructure, and team expertise.
BitNinja Server Security
- You need: Hosting providers managing shared servers, sysadmins running cPanel or Plesk, VPS owners wanting free server security, WordPress hosting environments
- You want to start with a free tier
- You're using: Linux (CentOS, AlmaLinux, Ubuntu, Debian, CloudLinux)
NAXSI
- You need: Teams already running NGINX who want lightweight inline WAF protection, budget-conscious deployments, applications with predictable request patterns, virtual patching use cases
- You want to start with a free tier
- You prefer open-source solutions
- You're using: NGINX, Linux (Debian, Ubuntu, CentOS), FreeBSD, OpenBSD, NetBSD, Docker
We recommend evaluating both options with a trial or free tier before committing. Consider your existing infrastructure, team expertise, compliance requirements, and budget.
