Safer by the Numbers

  • 32M+ Hashes of known CSAM in database
  • 1M+ CSAM files identified on customer platforms since launching
  • 330K+ Images classified as potential CSAM


Safer’s Hashing and Matching Services identify existing CSAM by hash matching against our CSAM database that includes 32M+ hashes. Our Video and Image Classifiers use machine learning to predict whether new content is likely to be CSAM and flags it for further review.

“Safer not only helps Bublup with legal compliance but also our shared mission of combatting child sexual abuse material on the internet. With Safer, Bublup can now review and report CSAM with greater efficiency when compared with our homegrown workflow, and it enables us to send potentially time-sensitive reports to the National Center for Missing and Exploited Children more quickly.”
