In order to improve detection capabilities on Bot Protect, we will roll out a new serving endpoint for response pages (Device Check, CAPTCHA, Block).

Target date

Monday, January 26, 2026

Required change

If you are using the frame-src directive in your Content-Security-Policy headers with a direct reference to geo.captcha-delivery.com, you will need to proceed with the change below:

  • Before: frame-src geo.captcha-delivery.com
  • After: frame-src *.captcha-delivery.com

Without this change, some of your end users might experience issues with displaying response pages in case of false positives.
