| What sets ADT apart from the rest?
When you're protected by ADT, you're protected by the largest, oldest, and we feel the best security company in the nation.
Throughout its 134 year history, ADT has led the way in the innovation of security services, from the simple Call Boxes of the early 1900's to the interactive video surveillance of the 21st century.
And this expertise is recognized. Over 400 of the Fortune 500 companies rely on ADT for their security needs, as does the largest residential customer base in the electronic security industry. In fact, with over 5 million customers nationwide and over 200,000 in Illinois alone' ADT's market share is nearly three times greater than its nearest competitor!
