Adding CAPTCHA Protection to a Drupal Site

CAPTCHA protection helps secure your Drupal site by reducing spam and blocking automated bots. On ruachost.com, you can add CAPTCHA functionality using the official CAPTCHA module.

Why Add CAPTCHA?

• Prevents automated spam registrations and form submissions.
• Protects login and comment forms from brute‑force attacks.
• Adds an extra layer of security to your site.
