Guardsmark has more than 125 offices throughout the U.S., as well as in Canada, Puerto Rico and the U.K.

It was founded in 1963 by Ira Lipman, who also is chairman and chief executive.

Neither company said whether the deal would bring any changes in executive ranks or a location for the headquarters of the combined operations.

The combined company, which is expected to employ about 60,000 in the U.S. and Canada, would be the largest U.S.-owned security company, Universal Protection said in a statement.
