Breck Foundation aims to prevent this from ever happening again. The work of the Foundation saves lives. Breck Foundation is a Southeast England based charity, with national relevance and impact. We reach thousands of children and young people in schools and other community settings every year with Breck's story. Our talks and educational materials fill a gap in the current UK curriculum that otherwise leaves children vulnerable to online grooming and exploitation.

I am the Chair of the GSMA Industry Specifications Issuing Group for the GSMA Security Assurance Scheme. The GSMA’s Security Accreditation Scheme (SAS) enables mobile operators, regardless of their resources or experience, to assess the security of their UICC and eUICC suppliers, and of their eUICC subscription management service providers. Two schemes operate under SAS:SAS for UICC Production (SAS-UP): This is a well-established scheme through which UICC and eUICC manufacturers subject their production sites and processes to a comprehensive security audit. Successful sites are awarded security accreditation for a period of one year, extending to two further years upon each successful renewal. This scheme has accredited some of the industry’s largest suppliers. GSMA also provides advice to its members on how to benefit from SAS-UP.SAS for Subscription Management (SAS-SM): To ensure industry confidence in the security of remote provisioning for eUICCs, a related security auditing and accreditation scheme exists for the providers of eUICC subscription management services.Much more information here - https://www.gsma.com/security/security-accreditation-scheme/
