National Protective Security Authority | NPSA 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.

There are also other nationally important assets or events, including high-profile iconic targets, where impact of damage would be equally serious even though these do not deliver an essential service. Our advice delivery extends to help the protection of such assets and events

Who We Work With

CPNI works with a variety of partners to identify risks to and reduce the vulnerability of the national infrastructure, focusing in particular on critical national infrastructure (CNI). Key partners include government departments and devolved government with responsibility for infrastructure sectors; businesses and organisations with those sectors that own or operate CNI; and other security specialists and advice delivery partners, including the Police.

CPNI recognise and support the Register of Chartered Security Professionals through delivery of a variety of training and other resources. Read more on their website here.
