Launched in October 2016, the NCSC has headquarters in London and brought together expertise from CESG (the information assurance arm of GCHQ), the Centre for Cyber Assessment, CERT-UK, and the Centre for Protection of National Infrastructure (which became the National Protective Security Authority, NPSA, in March 2023)

The NCSC provides a single point of contact for SMEs, larger organisations, government agencies, the general public and departments. It also works collaboratively with other law enforcement, defence, the UK’s intelligence and security agencies and international partners.
