About Us

Our History

Founder Bill Mullis was a provider of guard dogs for more than twenty years. In 1991, despite having his protective fleet on site, he was still experiencing break-ins.

He then decided to build, test, and continuously improve an electric security fence designed to offer the best protection for his place of business. In time, this electric security fence, due to its unmatched deterrence value, replaced the dogs and we soon became the Electric Guard Dog.


Our company quickly grew into a multi-faceted security business over the next two decades as companies in the auto auction, metal recycling, freight, and rental industries began seeing the results and cost savings that the Electric Guard Dog brought them. We’ve grown to become a security partner for market leaders in all of these core segments and recognized as the #1 Theft Deterrent System in the US.

In 2007, a majority interest in Electric Guard Dog was acquired by a group of private investors lead by Ulysses Management. Seeing the ever-increasing demand for our products and services, and the opportunity to broaden the reach of the product to new industries, the new ownership group began to put in place the infrastructure for growth. A key first step in the process was the hiring of CEO Jack DeMao and a new management team.

Electric Guard Dog has seen its reach and demand grow 63% since 2007, and the business community has taken notice. In 2010, we were named one of South Carolina’s 25 Fastest Growing Companies. In 2011, we joined the national rankings, listed #29 on SDM’s Top 100 Security Companies in the U.S. We’ve also been named to the 2011 Inc 500|5000 List of America’s Fastest Growing Private Companies.

It is our mission to stop crime before it happens. We are our customer’s security partner, and we take our responsibility seriously by employing the largest field technician and customer service team dedicated to electric security fences in the U.S. We are now integrating new technologies into our world-class system to create new, innovative and cost-saving solutions for our customers’ problems.
