About ADT

Based in Boca Raton, Florida, ADT is a major North American supplier of security and monitoring services. The company provides a range of services for both commercial and residential clients.

Founded over 130 years ago, ADT currently has more than 6 million customers in 230 American markets, including about 90% of Fortune 500 companies.

The company is also very involved in community service initiatives, and was one of the first sponsors of the National Crime Prevention Council (known best for its mascot, McGruff the Crime Dog).


The forerunner to ADT was formed in 1874 when several smaller telegraph delivery services merged to form the American District Telegraph Company. The company became a major player in the security protection industry when it began to offer advanced call boxes and multi-signal electric protection systems in the late 1800s.

ADT continued to grow and made another leap forward when it began to offer automated intrusion and other detection systems in response to demand brought on by labour shortages during the war years.

The company went public in 1969, and is listed on the New York Stock Exchange. ADT passed the 1 million customer mark in the mid-1990’s and in 1998 was purchased by Tyco International Limited.

ADT currently has about 6 million customers and operates in 230 US markets.
