Tony Wells, chief marketing officer of ADT, said the Boca Raton, Fla.-based company has been offering home security much longer — about 140 years. It also offers home automation services, but considers its focus on home security, as opposed to being an add-on service, to be a competitive advantage.

“We view security not just about the home, but about your personal security — and digital security,” Wells said. “We believe it’s core and central. It’s the only thing we do.”
