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.phpto 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.
Requirements and Compatibility
- WordPress multisite is not supported.
- Apache 1.3, Apache 2.x, and Nginx are supported.
- Rename Login cannot be combined with a login page URL change feature in another plugin. Enable it in only one plugin; using both can leave two login URLs available, or stop the login page from loading.
- CAPTCHA requires the PHP extensions
mbstringandgd. - WAF Tuning Support requires SiteGuard Server Edition on Apache.
