How it Works

Identify known and unknown CSAM with perceptual hashing and machine learning algorithms.

Flagged content is queued for further review by content moderators. Our Review Tool was designed with employee wellness in mind.

Review and report verified CSAM and securely store content in accordance with regulatory obligations.

Contribute hashes of new content to the Safer community, resulting in more content being removed from circulation and improved detection.

Break Down Data Silos

Your content moderators can add hashes to a self-managed hash list—SaferList—to protect against re-uploads, re-reviews and fine tune your matches. You’re able to instantly match against the content you discover, as well as filter out false positives. You also have the option to share your list anonymously with the Safer community and leverage lists contributed by fellow community members.
