Since 1999, Securitas AB has been the parent company of Pinkerton, a historically significant American detective agency.

[9] In 1983, Securitas was sold to the holding company Skrinet, and in 1985, it was acquired by Investment AB Latour, controlled by Gustaf Douglas.

Under the new ownership, the group focused on security, and in 1989, an international expansion began with acquisitions in Norway, Denmark, and Portugal and the establishment of Hungary.

In 2001, a new organization took effect, with five business areas according to the types of services offered, and Loomis Fargo & Company was acquired.

[18] In November 2007, the United Kingdom cash handling services of the division Loomis were sold to Vaultex Ltd., owned by HSBC and Barclays.

[19] In 2008, the division Loomis (cash handling) was distributed to the group's shareholders and listed at Nasdaq OMX Stockholm.

[20] In September 2010, Securitas acquired the security-services operations of Reliance Security Group in the United Kingdom.

In October 2015, Securitas acquired Diebold Incorporated's (NYSE-DBD) Electronic Security business in North America.

Operations outside of the Americas and Europe are reported in a separate category called "Other," which also includes central expenses.

[7] There are three operations centers in North America: Toronto, Ontario, Parsippany, New Jersey and Westlake Village, California.

Specialty assignments can also include fire-watch, fire extinguisher testing, access control and badging, console operations, safety auditing, alarm & emergency response, and what Securitas refers to as "customized and site-specific security tasks".

The subscription also includes incident response services for security concerns occurring when an officer is not currently on-site.

[39][38] Remote Guarding services involve Securitas officers monitoring a customer's site from an off-site command center.

If suspicious activity is noticed, Securitas can use speakers to talk to people on-site as well as notify the police or other emergency services when necessary.

Securitas also offers remote escort services that involve an off-site officer watching an employee walk to or from their vehicle.
