Security guarding in the UK is a critical aspect of maintaining security of assets and public protection for those that supply, buy, and rely on private security. Across various sectors, including commercial, residential, industrial, and public places, security officers play a vital role in deterring crime, preventing unauthorised access, and responding to emergency situations. This RISCAuthority Security Bulletin was revised in 2024 to update the 2018 version and provides guidance on types of security guarding, the legislation covering the private security industry, and the security guarding landscape.
