What we do at the NCSC
Our mission is to make the UK the safest place to live and work online so that everyone – whether at work or at home – can navigate the cyber landscape safely and with confidence.
Since 2016, the National Cyber Security Centre (NCSC) has safeguarded the UK’s critical systems and online services, delivering world-leading guidance, tools and frameworks for business and citizens alike. When cyber attacks occur – or services are disrupted – we provide incident response to minimise harm, restore operations, and help organisations get back on their feet.
The NCSC was formed by combining separate parts of government, MI5 and GCHQ to create the National Technical Authority for cyber security. We lead the UK’s defence against the most advanced cyber threats, including those from nation states, hackers, and cyber criminals.
The NCSC works closely with international allies, law enforcement and the UK’s intelligence and security agencies to ensure we understand the cyber threat, and how we can defend against it. We also harness talent across schools, universities, and the tech community, driving research into emerging technologies to explore new ways to reduce harm at scale. At the same time, we are investing in the UK’s national security by nurturing the next generation of expertise that the expanding cyber security sector needs to thrive.
