G4S security services

G4S is a globally recognized provider of security solutions, operating in over 100 countries. Originally tracing its roots back to Denmark and the United Kingdom, the brand has evolved through several high-profile mergers, most notably the 2004 merger between Group 4 Falck and Securicor.

The brand's reach spans various sectors, including electronic security systems, manned guarding, risk consulting, and specialized prison management services. Over the decades, G4S established itself as the world's largest security company by revenue and number of employees, becoming a staple in both public and private sector safety infrastructure.

In April 2021, G4S was acquired by Allied Universal, a leading security and facility services company based in the United States. This acquisition created a global security powerhouse, combining Allied Universal's dominance in North America with the extensive international network of G4S. Today, the G4S brand continues to operate as an international arm under the ultimate ownership of Allied Universal.
