SECURITY ONE was established as ERIE Security Engineering in 1975 in ERIE, Pennsylvania, to provide security guard services. Over the next three decades, SECURITY expanded its operations to 2 cities in 2 states, and now employs over 300 people. In 1996, we changed our name to SECURITY ONE         to better accommodate our growing stature and national service coverage.

SECURITY ONE is distinguished among its competitors by our substantial investment in information technology to manage service quality. We don’t want to hope it happened, we are determined to know it got done.

As a result of our service quality control leadership, in December 2004, SECURITY ONE became the first uniformed security company to be certified ISO 9001:2000 at its corporate operations and all of its field offices.

In 2005, SECURITY ONE began providing a multi-site Loss Prevention Program to a major food retailer.
