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. Without these services, the UK could suffer serious consequences, including severe economic damage, grave social disruption, or even large scale loss of life. CPNI advice is targeted primarily at the critical national infrastructure (CNI) - those key elements of the national infrastructure which are crucial to the continued delivery of essential services to the UK.
