WP Hardening is a security plugin for WordPress that conducts real-time audits to identify missing security best practices. It incorporates features such as checking for outdated plugins, PHP version security, and file permissions to enhance website protection. Users can also utilize the 'Security Fixer' to implement fixes directly from the WordPress dashboard. However, it is important to note that this plugin has been discontinued and is no longer maintained, meaning users will not receive updates or support moving forward.

The plugin’s features include hardening audits that assess WordPress version compliance, database password strength, and firewall protection. Additionally, it offers security fixers that disable unnecessary features to reduce vulnerability. Functionality such as changing the login URL and disabling XMLRPC helps prevent brute-force attacks. Despite its comprehensive features, users are advised to deactivate and delete this plugin and seek alternatives due to its discontinuation.
