It is a distinct entity, but benefits from access to MI5’s expertise and understanding of security threats. NPSA helps organisations within the United Kingdom understand the range of security threats they face, for example from terrorism, espionage, and state actors, and importantly what they can do to minimise their risk through how they operate day to day. NPSA provide and develop content and guidance that is more accessible to those with no or limited security background, alongside advice for security professionals and technical experts.
