Our History

Best Company Value Through Business

In 1999, Ms. Sandy Overton acquired a local security company in Fremont, California, established in 1995.  From this modest beginning, Overton Security Services has grown to be one of the largest and most respected security providers in their service areas across the state of California. To better serve our growing client list from San Diego to Redding, Overton Security has established offices in Sacramento, Pleasanton, and Los Angeles. Our major goal is professionalism in all areas.  Our greatest strength is that we demonstrate consistent dedication to the clients we serve. We treat all our officers as a natural resource and rely on their training, skills, and commitment to uphold the highest standards of professionalism. This ensures that our clients receive unparalleled service, and our unwavering dedication to their satisfaction remains our cornerstone.

Connecting with the Future of Security, Today!

Security for American business has changed considerably in the past few years and will keep changing as technologies and needs grow.  Security that was considered standard or reasonable a short time ago would not be acceptable today.  In the future, the specific functions and responsibilities for security solutions will evolve and become more dynamic.  We now have the capability to offer our clients, as it happens, accountability for our services in real-time.  With the new smart phone NFC technology, we are able to confirm almost immediately that our officers have arrived on time and are completing their patrols on schedule.  Our new technology allows us to deliver the highest quality of security services every day, at every location, for every customer we serve.  After all, this is what our customers expect and deserve.
