Electric Guard Dog, Columbia, S.C., a theft deterrent service, was named to the 2011 Inc. 500/5000 list of America’s fastest growing private companies.

The Inc. recognition arrives on the heels of Electric Guard Dog’s impressive cache of recent accolades, including ranking in the SDM 100, a report on the top 100 security companies in the United States, as well as South Carolina’s Top 25 Fastest Growing Companies in 2010.

By Inc.’s independent evaluation process, Electric Guard Dog has enjoyed a 63 percent growth spurt over the last three years, despite the recession.

Chief executive officer Jack De Mao credited Electric Guard Dog’s safe and effective products and services and intuitive pricing model for the company’s growth. “In these tough economic times, customers in all our markets are coming to realize they need to make investments to lower overall security costs and simultaneously stop break-ins.”

DeMao continued, “We’re honored to be included in Inc.’s list. But our most important ranking comes from our customers, who have dubbed us the No. 1 theft deterrent in the

United States.”

Electric Guard Dog is a security partner for more than 3,000 commercial and industrial locations across the nation, protecting businesses, providing a safer work environment for employees, and reducing total security costs.

Inc. introduced the 500 List of the fastest-growing privately held companies in the United States in 1982 and expanded to the 500/5000 List in 2007.
