NCSC Commodity Assured Service (CAS) scheme for Telecoms is the pan-government Public Sector Network (PSN) programme for telecoms providers. All telecoms services procured by public sector bodies are required to be certified to the CAS(T) standard, which is defined in the “Assured Service CAS Service Requirement Telecommunications” document, available from the NCSC website.
In order to achieve certification, the service provider must demonstrate compliance with the “Security Procedures Telecommunications Systems and Services” standard, which is based on the ISO/IEC 27001 standard.
Our experienced team can assess you to ensure you meet the CAS (T) scheme requirements. The process flow below shows the steps you need to take to get accredited and how we work with you as the service provider and NCSC and during the initial certification.
