ADT Inc. is an American security company that designs, installs and monitors security systems and smart home solutions for residential and business customers. Its technical work spans smart home technology, AI-powered smart home integration, and monitoring and alarm systems - a line of development that traces back to the company's origins in telegraph-based telecommunications. Founded in 1874, ADT describes itself as America's #1 security provider, serving millions of customers nationwide through the largest network of smart home security professionals in the United States.
The company's offerings include professionally installed and monitored home security systems, AI-driven smart home security integration, and security solutions and support for businesses. Installation and professional monitoring remain central to the model: systems are delivered and serviced by trained technicians, with monitoring operations supporting customers around the clock.
ADT operates across the United States and has been in business for 150 years. The company states that its culture is built on trust, integrity and a focus on customer safety, and that it offers generous benefits, career advancement opportunities and a diverse and inclusive environment. Employees are encouraged to become "Everyday Heroes", and the firm runs the ADT Safe Places philanthropy programme. Success, in the company's own framing, is measured by the peace of mind delivered to customers.
