SiteGuard WP Plugin helps protect WordPress sites by strengthening login and admin-area security. It helps reduce brute-force login attacks, password list attacks, comment spam, and unauthorized access to /wp-admin/.

Main Features

  • Admin Page IP Filter: Restricts wp-admin access to IP addresses that have successfully logged in.
  • Rename Login: Changes the URL of the login page from wp-login.php to a custom path.
  • CAPTCHA: Adds CAPTCHA to login, comment, password reset, and user registration forms.
  • Login Lock: Temporarily locks out IP addresses after repeated failed login attempts.
  • Login Alert: Sends email notifications when users log in.
  • Fail Once: Intentionally rejects the first valid login attempt and requires the user to try again shortly after.
  • Protect XML-RPC: Disables pingbacks or all XML-RPC access to help prevent abuse.
  • Block Author Query: Helps prevent username leakage through /?author=<number> requests.
  • Update Notifications: Sends email notifications when updates are available for WordPress core, plugins, or themes.
  • WAF Tuning Support: Creates exclusion rules to help prevent false positives when SiteGuard Server Edition WAF is installed.

  • Apache 1.3, Apache 2.x, and Nginx are supported.
