Command Security commenced operations as R. J. Thompson, Inc. in 1980. This Herndon, Virginia–based corporation principally engaged in furnishing uniformed guard and investigative services under the direction of its founders and sole stockholders. In 1980, the stockholders acquired 50% of the outstanding stock of R.J. Thompson, Inc. and in 1983, acquired the remaining 50%. Later that same year, stockholders acquired Command Security, a Connecticut Corporation engaged in uniformed security and investigative services.
In 1983, the Company discontinued the use of the R.J. Thompson, Inc. name and began operating as Command Security. In 1986, all operations were consolidated under the New York corporation, now formally known as Command Security Corporation. Command Security then expanded its business through internal sales efforts and targeted acquisitions.
In 1995, Command Security acquired the assets of United Security Group - a New York regional security services company with operations also in California. The acquisition included Aviation Safeguards, a leading provider of contract services to the aviation security and services industries.
In April 2007, Command Security Corporation completed the acquisition of California-based Brown Security Services, P.A., including its wholly-owned subsidiaries, Strategic Security Services, Inc. and Rodgers Police Patrol, Inc.
Today, Command Security Corporation is one of the leading providers of contract security and related services in the United States. With more than 40 operating offices, Command Security provides a variety of protective and loss prevention programs to numerous corporate, industrial, commercial, institutional, municipal, governmental and residential customers.
