Have you ever noticed the G4S logo on the shirts of the security personnel in your company?
G4S plc (formerly Group 4 Securicor) is a British multinational security services company headquartered in Crawley, England.
The company was set up in 2004 when London-based company Securicor amalgamated with Danish business Group 4 Falck. The company offers a range of services, including the supply of security personnel, monitoring equipment, response units and secure prisoner transportation. G4S also works with governments overseas to deliver security.
It is the world’s largest security company measured by revenues and has operations in around 125 countries. With 618,000 employees, it is world’s third-largest private employer, the largest European and African private employer, and among the largest on the London Stock Exchange.
G4S has its origins in a guarding business founded in Copenhagen in 1901 by Marius Hogrefe, originally known as København Frederiksberg Nattevagt (English: Copenhagen and Frederiksberg Night Watch) and subsequently renamed Falck (English: Falcon). In 2000, Group 4, a security firm formed in the 1960s, merged with Falck to form Group 4 Falck and by 2000 the company was described as “the world’s largest private security systems company”.
G4S’s core services include ‘manned security services‘ – where it provides trained and screened security officers. The company also provides ‘security systems’ such as access control, CCTV, intruder alarms, ﬁre detection, video analytics and security and building systems integration technology. ‘Monitoring and response services’ is another core service, where G4S provides key holding, mobile security patrol and response services and alarm receiving and monitoring facilities.
