SiteGuard WP Plugin

The SiteGuard WP Plugin is a comprehensive security tool designed to enhance WordPress security, focusing primarily on defending against brute force login attacks. The plugin offers multiple features including Admin Page IP Filter, which restricts access to the admin page based on IP addresses; Rename Login, which allows the renaming of the default login page to deter unauthorized access; and CAPTCHA, which adds a layer of human verification to minimize automated attacks and comment spam. Additional functionalities include Login Lock, which blocks repeated failed login attempts; Login Alert, which sends email notifications for login activities; and Fail Once, which purposely fails the first login attempt to thwart password list attacks. The plugin also disables potentially vulnerable features such as Pingback and Block Author Query to protect user data. Moreover, it includes an Update Notify system to keep the WordPress core, plugins, and themes up-to-date. For advanced users, the WAF Tuning Support function helps to fine-tune Web Application Firewall (WAF) settings to prevent false positives while maintaining security. However, the plugin does have some limitations, including non-support for WordPress multisite functionality and specific web server and PHP library requirements.
