NinjaFirewall (WP Edition) – Advanced Security Plugin and Firewall

NinjaFirewall (WP Edition) is a standalone firewall that stands in front of WordPress, providing advanced security features that are not usually available at the WordPress level. It can hook, scan, sanitize or reject any HTTP/HTTPS request sent to a PHP script before it reaches WordPress or any of its plugins. NinjaFirewall includes the most powerful filtering engine available in a WordPress plugin and offers the fastest and most efficient brute-force attack protection for WordPress. However, it requires at least PHP 7.1, MySQLi extension and is only compatible with Unix-like OS (Linux, BSD), not Microsoft Windows.
