A subsidiary of Allied Universal, the world's largest private security company. It runs private prisons in Australia and the UK and deports immigrants in the US. It divested from all of its activities with the Israeli government following a global campaign.

G4S PLC, headquartered in London, is the largest private security company in the world. In 2021, it was acquired by Allied Universal, the largest American private security company. At the time of acquisition, the combined company was the seventh-largest employer in the world and the third-largest employer in North America, after Walmart and Amazon.

Allied Universal is controlled by Canada's second-largest pension fund - Montréal-based Caisse de dépôt et placement du Québec (CDPQ), which became its largest shareholder when it financed the acquisition of G4S - and U.S.-based private equity firm Warburg Pincus, its second-largest investor.

Until 2017, G4S was deeply involved in several projects of the Israeli occupation. Following a global campaign, the company sold almost all of its business activities in Israel. In 2023, it announced that it would sell its last business activity with the Israeli government: a minority stake in Policity, the Israeli National Police Academy.

G4S also used to be one of the main companies involved in the jailing of youth in the U.S. and U.K., a business that it also divested from in 2017. (See below for more details on these divestments.)

US Deportations

G4S has been conducting deportations for the U.S. government since at least 2006. Through its subsidiary G4S Secure Solutions, G4S has multiple large and long-term contracts with Customs and Border Protection (CBP) and Immigration and Customs Enforcement (ICE), providing these agencies with transportation services and guards. Between 2008 and June 2023, the company's contracts with CBP and ICE amounted to just over $1 billion. G4S was highlighted as one of 14 border security "giants" in a 2019 report by the Transnational Institute and No Más Muertes.

Under its contracts with CBP, G4S transports immigrants arrested at the U.S.–Mexico border to immigration jails throughout the U.S. This includes temporarily incarcerating immigrants in transit or those awaiting "processing." A company promotional brochure describes these transports as "the bus no one wants to catch."

Similarly, G4S provides "detainee transportation services" to ICE field offices and Enforcement and Removal Operations (ERO) (i.e., deportation) offices. As of June 2023, the company has such contracts with ICE offices in Los Angeles, Phoenix, San Francisco, and San Antonio.

The company has long been accused of mistreating immigrants under its care. For example, nine women transported by G4S for ICE in 2017 "were shackled by their hands and feed, then forced to ride in a boiling, windowless van for hours with no food, water, medication or toilet access," according to a lawsuit brought by the ACLU. They spent over 24 hours being transported within California in what should have been a five-hour ride. While caged in the back of a G4S van, some of them fainted and vomited, suffered heat stroke symptoms, and believed they would die.

Private Prisons Around the World

United Kingdom

G4S operates four prisons in the U.K., which together incarcerate over 5,000 individuals: Altcourse Prison, Oakwood Prison, Parc Prison and Young Offender Institute, and Rye Hill Prison. The company also formerly operated two immigration jails/deportation centers located next to London Gatwick Airport: Brook House and Tinsley House Immigration Removal Centres.

G4S's U.K. prisons have faced numerous allegations of inhumane conditions, including systemic violence, physical and emotional abuse, child abuse, and prison labor. These issues have caused G4S to lose multiple contracts.

In 2020, following reports of "shocking" physical and verbal abuse of immigrants detained at Brook House, G4S announced that it would no longer run either of its two U.K. immigration jails. These jails are now operated by Serco.

One year prior, the company was "permanently stripped" of its contract for operating the "crisis-hit" Birmingham Prison following reports of ongoing violence, "filthy and degraded" conditions, routine instances of self-harm, riots, and other issues. G4S operated Birmingham Prison from 2011 to 2018, when the U.K. government seized control of the prison.


G4S operates two prisons in Australia—Mount Gambier Prison and Port Phillip Prison—and provides security services to Malmsbury Youth Justice Centre, a youth jail in Victoria. In addition, the company formerly operated Australia's Manus Regional Processing Centre, an immigration jail located in Manus Provence in Papua New Guinea.

As with its prisons in the U.K., G4S's prisons in Australia have faced allegations of "degrading and inhumane conditions," physical assaults, deficient safety protocols, and other similar issues.

In 2014, the company's contract for operating Australia's Manus Island immigration jail was terminated following several violent incidents, including "days of rioting" that resulted in 77 injuries and the beating death of an Iranian asylum seeker by two G4S guards. G4S faced multiple lawsuits in relation to this incident, in which the immigration jail was described, for example, as "unsanitary and marred by violence."

South Africa

Between 2000 and 2023, G4S operated the world's second-largest private prison, Manguang Correctional Centre, located in Bloemfontein, South Africa. Through its partial ownership of Bloemfontein Correctional Services, G4S had a 25-year contract, set to expire in 2025, with the South African Department of Correctional Services to run the prison.

In May 2023, however, the South African government canceled the contract, taking over Manguang prison and stating that the company "is neither competent, nor suitable to continue" operating the prison. This followed a high-profile incident in which an individual incarcerated at Manguang escaped with the help of G4S guards. The company announced that it would stop operating prisons in South Africa altogether.

This was the second time the South African government took over Mangaung prison; the first takeover occurred in 2013 following a series of prison riots. Subsequent investigations revealed that G4S staff used electric shocks and forcible antipsychotic drug injections against incarcerated individuals. Despite this, the government returned the prison to G4S management in 2014. In 2015, 43 people incarcerated at Mangaung sued G4S for torture following revelations of a cover-up of the deaths of several incarcerated individuals.

E-carceration (Electronic Monitoring)

In 2022, G4S's parent company, Allied Universal, acquired Attenti, one of the world's largest electronic monitoring companies (formerly owned by 3M). Allied combined the company with G4S Monitoring Technologies to create Allied Universal Electronic Monitoring Services. Attenti claims to monitor over 200,000 people in more than 30 countries, as of 2013.

Attenti is one of four major providers of electronic monitoring in the U.S. Since 2013, it has provided electronic monitoring to state agencies through a master contract with Washington State, which other states can join through the National Association of State Procurement Officials. Participating states include Alaska, Arizona, Arkansas, Connecticut, Hawaii, Iowa, Louisiana, Montana, New Mexico, Oklahoma, Oregon, Rhode Island, Utah, Vermont, Washington, and West Virginia. The states of Florida, Idaho, Indiana, Michigan, and Pennsylvania, as well as Cook County, Ill., and the federal agency that oversees probations in Washington, D.C., hold independent contracts with Attenti.

Before merging with Attenti, G4S did not provide electronic monitoring services in the U.S., but had provided such services to government agencies in 20 other countries, including Australia, El Salvador, France, New Zealand, and the U.K.

In the past, G4S had a different electronic monitoring business, G4S Justice Services, which it sold to Sentinel Offender Services in 2012. At the time, G4S claimed to be "the world's largest provider of electronic monitoring services," monitoring the movements of 35,000 people across 20 countries.

Divesting From Israeli Apartheid

Until 2017, G4S was deeply involved in several projects of the Israeli occupation of Palestine through its Israeli subsidiary, G4S Israel (formerly Hashmira). As reported by Who Profits in 2011, the company provided security services and equipment to multiple illegal Israeli settlements, military checkpoints, and prisons.

At the time, G4S was one of the major providers of security systems and services to all branches of the Israeli government, including military bases and facilities and equipment of the Israeli security and finance industries. Its security patrol units, the company boasted, were manned by "combatants who graduated elite combat units in the Israeli army."

G4S was one of the companies highlighted in the 2010 Russell Tribunal on Palestine. A global campaign targeting the company followed, with dozens of institutions around the world—including cities, universities, churches, unions, United Nations agencies, and the European Parliament—dropping G4S as their security contractor. Similarly, multiple large institutional investors, like the Gates Foundation, the California Endowment, and a dozen mainline protestant denominations, divested from their G4S shares. (For a full list of these actions, see the "Economic Activism Highlights" section below.)

In 2016, as a result of this mounting pressure, G4S announced that it would sell its Israeli subsidiary to private equity firm FIIMI Opportunity Funds for $110 million. In 2017, the acquisition was completed. The Israeli company subsequently rebranded as G1 Secure Solutions and became independently publicly traded.

After the sale, G4S retained a minority stake in Policity, the company that built and operates the Israeli National Police Academy. Policity was established as a joint venture of G4S and Israeli infrastructure company Shikun & Binui, with each company owning 50%. The training facility opened in 2015 under a 20-year contract until 2035. After selling its Israeli subsidiary in 2017, G4S split its 50% stake with G1 Secure Solutions, with each company owning 25%.

Following the 2021 acquisition of G4S by Allied Universal—with financial backing from CDPQ (see above)—a Québec coalition ran a campaign calling on CDPQ to pressure G4S to divest itself of its shares in Policity. During public testimony in 2023, after hearing about conditions in Palestine, the head of CDPQ said that this "is not the kind of activity that we endorse at all." He also revealed that Allied had pledged to sell its stake in Policity as part of its acquisition of G4S.

In May 2023, G4S announced that it would sell its stake in Policity to G1. As of June 2023, this sale is pending the approval of the Israeli government and the banks that originally financed the project.

Divesting From Youth Detention Centers

Until 2017, G4S was one of the main companies in the youth detention industry in the U.S. and U.K. In 2016, the company announced that it would sell several of its most controversial businesses, including its youth jail subsidiaries.

In 2017, G4S sold its U.S. youth jail subsidiary, G4S Youth Services, for $56.5 million to BHSB Holdings, which later rebranded as TrueCore Behavioral Solutions. At the time of the sale, G4S Youth Services managed 28 youth detention facilities in Florida, Tennessee, and Texas, as well as additional youth probation services, residential facilities, and mental health and outpatient services. G4S's youth jails faced numerous allegations of sexual abuse, excessive force, and recurring riots, leading to several lawsuits against the company.

In 2016, G4S sold Homes2Inspire, its U.K. youth jail subsidiary, to the Prospects Group, which was acquired one year later by the charity organization Shaw Trust. At the time of the sale, Homes2Inspire operated 18 youth jails in the U.K. The company faced repeated reports of physical and mental abuse by G4S staff against youth.
