A simpler path to a safer Internet: an update to our CSAM scanning tool

Cloudflare has updated its CSAM Scanning Tool to remove the need for site operators to create and share their own unique NCMEC credentials, a change that has driven a dramatic rise in adoption. The post explains that the tool relies on fuzzy hashing to generate perceptual fingerprints of images, allowing matches even when content is altered, and that it now enables scanning of content uploaded to a site with less manual effort.

According to the National Center for Missing and Exploited Children (NCMEC), adoption of the tool has increased by 1,600% since the change was introduced in February. The process remains straightforward: enable the tool on your Cloudflare zone, scan and detect CSAM, and Cloudflare blocks the URL to identified matches while notifying the site owner.

The update aims to make CSAM protection available to a broader range of websites, not just large platforms, and Cloudflare invites developers to review the technical details in the documentation.
