NinjaFirewall (WP+ Edition)

NinjaFirewall (WP+ Edition) is a web application firewall designed for WordPress that operates at the HTTP request level, before requests reach WordPress or its plugins. It functions as a standalone firewall while being installable as a WordPress plugin, providing security capabilities typically found only in server-level applications like Apache ModSecurity or PHP Suhosin extensions.

• Request Scanning and Sanitization - Hooks into incoming requests to scan, sanitize, or reject HTTP/HTTPS traffic sent to PHP scripts
• Comprehensive Script Protection - Protects all scripts located in blog installation directories and subdirectories, including those outside the WordPress package, encoded PHP scripts, and backdoors
