2024, 2025
Kathryn Rifenbark is the Director for CyberTipline, in the Exploited Children Division (ECD) at the National Center for Missing & Exploited Children (NCMEC), where she has worked for over 14 years. Kathryn is responsible for overseeing day-to-day operations of NCMEC’s CyberTipline, the reporting mechanism within the U.S. for suspected online child sexual exploitation, with a concentration on its response to reports received from members of the public. In addition, she manages NCMEC’s programs to notify companies of hosted CSAM material, to reduce revictimization of survivors. Kathryn helped spearhead NCMEC’s efforts to improve resources for reporting people and survivors of child sexual abuse material and continues that work today by liaising with law enforcement, victim service providers, and child serving professionals.
