CYREN is latest company to join Internet Watch Foundation

Published:  Tue 2 Feb 2016

The Internet Watch Foundation (IWF) starts its 20th Anniversary Year by welcoming five new companies into its membership. The latest to be announced is CYREN, a global cloud-based security company.

CYREN deploys Web, email and anti-malware products globally to fellow IWF members such as Dell, Google and Microsoft. CYREN is interested in taking the IWF Image Hash List service once it’s launched later this year.

The Image Hash List is a list of unique identifiers for images of child sexual abuse. Each image is converted into a unique code called a hash. Hashes automatically identify known child sexual abuse images without needing to examine each image individually. This can dramatically improve the ability to prevent online distribution of these images.

Dan Maier, vice president of marketing at CYREN, said: “CYREN strongly supports IWF’s mission. We are excited to be working with them to help stop the dissemination of child sexual abuse images. Armed with IWF’s upcoming feeds, CYREN will be able to provide its customers with a more effective way to block these materials in email and on the Web.”

Susie Hargreaves, IWF CEO, said: “It’s great to see an influx of new Members so early in 2016. CYREN will be just one of our Members who will begin using the Image Hash List. For companies like CYREN, the new technology is a valuable addition to their safety products, but more importantly it will bolster our global efforts to disrupt access to child sexual abuse material online.”
