About CPNI

We are the UK government’s National Technical Authority for physical and personnel protective security

Last Updated 09 August 2021

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.

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.

CPNI is committed to equality, diversity and inclusion (EDI). EDI is integral to our culture and working practices, as well as our protective security efforts. We also work closely with key partners to promote greater EDI in the wider security profession.



 CPNI’s  commitment to equality, diversity and inclusion (EDI)

 CPNI  is committed to supporting EDI within our organisation and developing a workforce with a range of backgrounds, identities, education and experience. Promoting EDI isn’t just about doing the right thing, but goes to the heart of what we exist to do. The success of our cutting-edge protective security advice as a National Technical Authority depends on our ability to draw on the best people, with the best skills, and to engage with and understand our customers.

We also work closely with partners to promote greater EDI in the wider security profession. It is widely recognised that improving EDI is crucial for the success and sustainability of the profession. With greater EDI we can ensure that the profession both attracts and retains a diverse workforce, with fair treatment and opportunity for all. In doing so, we create an inclusive environment where everyone can thrive.
