We are a locally owned, family business. We incorporated CornerStone in 1995 and began operations in Denver in January 1996. Since that time we have served thousands of clients providing finest, state of the art security equipment along with old-fashioned service. In this day of mass merchandizing and lower quality to be the cheapest product or service, we take a different approach. We don't believe that "one size fits all." Once the system is installed, you, the buyer will have to live with it for a long time.

We survey every facility and design your system to meet your needs and your budget. It is our sincere hope to be your security company. Our objective is to assist you in making the most informed decision. After all, it is your money, isn't it?
