Ninja Firewall WP+ Edition v4.8.1 - WordPress Plugin

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.

Key Features

• Web Application Firewall - Operates as a full firewall standing in front of WordPress, scanning and filtering HTTP/HTTPS requests before they reach WordPress or plugins

• 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
• Brute-Force Attack Protection - Includes brute-force attack detection and prevention mechanisms
• Unix Shared Memory Support - Uses Unix shared memory for inter-process communication in the WP+ Edition
• Multisite Support - Compatible with WordPress multisite installations
• Response Body Filtering - Web filter capability to process and filter HTTP response bodies (WP+ Edition)
• HTTP Response Headers - Manages and modifies HTTP response headers for enhanced security
