A true Web Application Firewall.
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 sits in front of WordPress.
It will 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.
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.
See our benchmark and stress-test: WordPress brute-force detection plugins comparison.
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.
NinjaFirewall is very fast, optimised, compact, and requires very low system resource. Don't believe us? See for yourself: download and install GoDaddy's P3 Plugin Performance Profiler and compare NinjaFirewall performances with other security plugins.
Each NinjaFirewall menu page has a contextual help screen with useful information about how to use and configure it. If you need help, click on the Help menu tab located in the upper right corner of each page in your admin panel.
