You can protect your Joomla website from spam with the Cloudflare Turnstile CAPTCHA. It's a solution developed to protect websites from automated access (bots). The primary goal is to offer a high level of security with minimal impact on the user experience. Sometimes, the user or site visitor (guest) may not even be required to take any additional actions — the verification can occur in the background, no visual puzzle anymore. Turnstile’s ‘Managed’ mode is completely free to everyone for unlimited use. And Turnstile is WCAG 2.1 Level AA compliant. Turnstile meets ePrivacy Directive, GDPR, and CCPA compliance requirements, as well as the strict requirements of our privacy commitments.

Notice!  To use Cloudflare reCAPTCHA, you need at least SPPB Pro 5.4.6 (Jan 2025). Of course, we recommend using a much more current version. 

This powerful CAPTCHA service seamlessly integrates with SP Page Builder Pro 5.x / 6.x, allowing you to use it in the Form, Opt-in, and Contact Form addons for enhanced security.
