The global security services industry was worth 132 billion U.S. dollars in 2020, suffering minor losses due to the coronavirus pandemic. Asia held the largest share of this market, accounting for approximately 28 percent of the total, followed by Europe, and then North America. The revenue of the security services industry generated 46 billion U.S. dollars in the United States in 2020. In that same year, around 810,000 security guards were employed by the industry in the United States.
The three largest companies in the U.S. outsourced security services market are G4S, Securitas and Allied Universal Security Services, with a combined revenue exceeding 17 billion U.S. dollars reported in 2020. This was over half of the 28 billion U.S. dollars revenue reported in the U.S. outsourced security services market for that year.
