National Cyber Security Centre

National Cyber Security Centre

Overview

The National Cyber Security Centre (NCSC) is the UK government's dedicated authority on cyber security. Based in London, the NCSC operates as the technical authority and strategic lead for cyber security matters across government and the wider UK economy. Rather than a traditional membership association, the NCSC functions as a government agency that provides guidance, standards, incident response support and expertise to protect the UK against cyber threats.

The NCSC serves organisations across all sectors — from critical national infrastructure and public sector bodies to private companies of all sizes, as well as individuals seeking cyber security advice. It plays a central role in the UK's cyber security landscape, acting as the authoritative voice on cyber threats, best practice, and protective measures.

The NCSC's guidance and services are relevant to:

Unlike traditional membership organisations, the NCSC does not operate a formal membership model with applications or subscription fees. Instead, its services and guidance are made freely available to support and protect UK organisations and individuals.
