Break Down Data Silos

Your content moderators can add hashes to a self-managed hash list—SaferList—to optimize your CSAM detection. 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.
