Universal Protection Service was a private security company in the United States.

It was part of Santa Ana, California-based Universal Services of America, which merged in 2016 with fellow security service provider AlliedBarton to form Allied Universal.

In February, Robert Stone, a former employee of Universal Protection Service filed an arbitration claim alleging that the company failed to pay overtime wages for all hours worked as well as minimum wage.

The company denied the allegations, but entered into a $30 million settlement to avoid the cost of litigation.
