What It Does

NinjaFirewall (WP Edition) is a true Web Application Firewall. Although it can be installed and configured just like a plugin, it is a stand-alone firewall that stands in front of WordPress.

It allows any blog administrator to benefit from very advanced and powerful security features that usually aren’t available at the WordPress level, but only in security applications such as the Apache ModSecurity module or the PHP Suhosin extension.

NinjaFirewall can hook, scan, sanitise or reject any HTTP/HTTPS request sent to a PHP script before it reaches WordPress or any of its plugins. All scripts located inside the blog installation directories and sub-directories will be protected, including those that aren’t part of the WordPress package. Even encoded PHP scripts, hackers shell scripts and backdoors will be filtered by NinjaFirewall.

NinjaFirewall includes the most powerful filtering engine available in a WordPress plugin. Its most important feature is its ability to normalize and transform data from incoming HTTP requests which allows it to detect Web Application Firewall evasion techniques and obfuscation tactics used by hackers, as well as to support and decode a large set of encodings.

By processing incoming HTTP requests before your blog and any of its plugins, NinjaFirewall is the only plugin for WordPress able to protect it against very large brute-force attacks, including distributed attacks coming from several thousands of different IPs.

NinjaFirewall can alert you by email on specific events triggered within your blog. Some of those alerts are enabled by default and it is highly recommended to keep them enabled. It is not unusual for a hacker, after breaking into your WordPress admin console, to install or just to upload a backdoored plugin or theme in order to take full control of your website.

To get the most efficient protection, NinjaFirewall can automatically update its security rules daily, twice daily or even hourly. Each time a new vulnerability is found in WordPress or one of its plugins/themes, a new set of security rules will be made available to protect your blog immediately.

NinjaFirewall is very fast, optimised, compact, and requires very low system resources. It looks and feels like a built-in WordPress feature. It does not contain intrusive banners, warnings or flashy colors.

FAQ

NinjaFirewall stands between the attacker and WordPress. It can filter requests before they reach your blog and any of its plugins. This is how it works :

Visitor -> HTTP server -> PHP -> NinjaFirewall #1 -> WordPress -> NinjaFirewall #2 -> Plugins & Themes -> WordPress exit -> NinjaFirewall #3

And this is how all WordPress plugins work :

Visitor > HTTP server > PHP > WordPress > Plugins -> WordPress exit

Unlike other security plugins, it will protect all PHP scripts, including those that aren’t part of the WordPress package.
