The Security Industry Authority (SIA), established by the 2001 Private Security Industry Act, provides a relatively light-touch regulation of the sector. The SIA website outlines its role (https://www.sia.homeoffice.gov.uk/Pages/home.aspx ) and the process by which it licenses the industry. The site addresses the nature of the licensing process that it oversees, and responds to some criticisms of the system.

The extent and long-standing of the security industry is demonstrated by the breadth of topics covered by the American Society of Industrial Security, which was established in 1955 and has approximately 35,000 members organised into more than 200 ‘chapters’ worldwide. The ASIS website, https://www.asisonline.org, provides details of its work and the security industry more generally.

The website of the National Community Safety Network (https://communitysafetynet.com/) contains a host of resources relating to the Crime and Disorder Reduction Partnerships and the growing range of agencies engaged in policing.
