Allied Universal is an American private security and staffing company, based in Conshohocken, Pennsylvania and Irvine, California.

[12] Also in 2018, the radio program This American Life ran an hour-long feature story about sexual harassment and racism within Allied's operations at JFK airport and the company's responses to it.

[13] In response to the allegations, the company issued a statement saying these “isolated incidents are not indicative of our culture and work ethic,” and it has “zero tolerance against sexual harassment.” A related case was later voluntarily dismissed at the plaintiffs’ request.

[12] In July, Allied Universal announced the purchase of Georgia-based US Security Associates along with its affiliate Staff Pro for $1.5 billion.
