National Protective Security Authority (NPSA)

The National Protective Security Authority (NPSA) is part of MI5 and is the National Technical Authority for physical and personnel protective security. By making the UK more resilient to national security threats, we help to make the UK safe. We help organisations understand the range of threats they and the UK face, for example from terrorism, espionage, and state actors. Based on our world-leading research and development programme and the latest intelligence, we provide advice and guidance on what organisations can do to minimise their risk through how they operate day to day. In March 2023, NPSA absorbed the responsibilities of the Centre for the Protection of National Infrastructure (CPNI), but with a broader remit, reflecting the fact that the threats the UK faces today extend far beyond critical national infrastructure.
