AWS WAF Captcha helps block unwanted bot traffic by requiring users to successfully complete challenges before their web requests are allowed to reach AWS WAF-protected resources. WAF Captcha challenges are simple for humans while remaining effective against bots. Starting today, AWS WAF Captcha is adding ten additional languages - Arabic, German, Spanish, French, Italian, Dutch, Japanese, Portuguese, Turkish, and Chinese (simplified) - and is designed to meet WCAG accessibility requirements. AWS WAF Captcha uses the client browser language settings to select the language of the challenge, so there is no additional configuration needed. In addition, you will see a new option to change the Captcha page language, if needed.

AWS WAF Captcha is available in all AWS regions supported by AWS WAF, including China (Beijing, operated by Sinnet), China (Ningxia, operated by NWCD) and GovCloud regions. For detailed information, see the AWS WAF developer guide. WAF Captcha usage is charged based on the number of WAF Captcha challenges attempted, in addition to standard AWS WAF service charges. See the AWS WAF Pricing page for more details.
