WordPress spam blocker

  • Block contact-form spam from your website – integrates with Contact Form 7, Kadence Blocks, WP Forms, Beaver Builder Pro and Elementor Pro Forms. More integrations are on their way.
  • Block WordPress comment-spam.
  • Choose to only allow messages from specific countries.
  • Use the Spam Shield API in your own projects, with an API key and the Spam Shield Docs.

For agencies & hosting providers

Grab a volume licence and deploy Spam Shield in Agency Mode, creating a value-added service for your clients. You can integrate your own branding with the Spam Shield for WordPress plugin too.

IP address reputation

Check whether an IP address is known for spamming, probing for vulnerabilities or should be hard-blocked. Also returns a “trusted” status for selected network providers like GMail, PayPal, etc, so you don’t end up blocking a key infrastructure provider by mistake.

In your own projects

The API is fully documented and easy to integrate into your own projects. Check out the documentation to learn how.
