The National Security Inspectorate (NSI) is a national regulatory body inspecting firms who provide security and related services across the United Kingdom. It brings together two well-established organisations, the National Approval Council for Security Systems (NACOSS) and the Inspectorate of the Security Industry (ISI) covering electronic security and manned services respectively.
NSI promotes and monitors consistent high standards across activities relating to the secure environment so that specifiers and consumers can purchase security products and services with confidence from reliable, independently assessed suppliers.
