What we do

Our advice aims to reduce the vulnerability of the national infrastructure to terrorism and other threats, keeping the UK's essential services (delivered by the communications, emergency services, energy, finance, food, government, health, transport and water sectors) safer. CPNI advice is targeted primarily at the critical national infrastructure (CNI) - those infrastructure assets (physical or electronic) that are vital to the continued delivery and integrity of the essential services upon which the UK relies, the loss or compromise of which would lead to severe economic or social consequences or to loss of life
