About Our
Cunningham Security
Cunningham Security Systems was established by Paul and Nancy Cunningham in 1983. Their mission was to provide custom designed, high-quality monitored security systems for homes and businesses throughout Southern Maine. After more than 20 successful years, the Cunningham’s decided to retire, and Mike Major purchased the company.
Mike is a Maine native; having grown up, living, working, and raising his two boys in the Greater Portland area. He brings over 30 years of customer service and business expertise to the company. His commitment to provide the best combination of products and customer service, while maintaining affordable pricing for all existing and future customers, has led to thousands of happy customers.
