NTIA's Communications Supply Chain Risk Information Partnership (C-SCRIP)

C-SCRIP program

Welcome to the Communications Supply Chain Risk Information Partnership (C-SCRIP). C-SCRIP is a program designed to share supply chain security risk information with trusted communications providers and suppliers. Our goal is to improve small and rural communications providers’ and equipment suppliers’ access to information about risks to key elements in their supply chain. NTIA will tailor this risk information to be relevant and accessible to the C-SCRIP community. Additionally, C-SCRIP will share public security alerts, relevant training events, and grant funding opportunities from government partners with this community.

Please sign up here to join our mailing list.

The C-SCRIP program was called for in the Secure and Trusted Communications Networks Act of 2019. The Act established a Federal Communications Commission program to reimburse smaller providers for removing and replacing equipment and services that threaten national security. This information sharing program, mandated by Section 8 of the Act, was intended to ensure that small, rural providers have access to the supply chain risk information they need before they make an investment, which should mitigate further “rip and replace” programs in the future.
