Centre for the Protection of National Infrastructure (CPNI)

CPNI is the government authority for protective security advice to the UK national infrastructure. Our role is to protect national security by helping to reduce the vulnerability of the national infrastructure to terrorism and other threats. We are accountable to the Director General of MI5.

CPNI works with the National Cyber Security Centre (NCSC), Cabinet Office and lead Government departments and agencies to drive forward the UK's cyber security programme to counter cyber threats.
