About Us | Comprehensive Security Services, Inc.

Founded in 1989, Comprehensive Security Services, Inc. is a family-owned and operated company specializing in serving clients in both the public and private sectors. Discover more about CSSI and the diverse range of services we offer in California and Nevada.

Supplying Superior Armed and Unarmed Security Services for Nearly 40 Years

When CSSI was first established in the late 1980s, our goal was simple: We sought to provide more responsive security services to clients than our competitors. Since our early days, we have grown immensely, working closely with countless clients along the way. However, we have consistently made it our mission to extend top-notch armed and unarmed security services to those who trust us to keep them and their properties safe.

While gradually transforming into one of the top private security providers in California and Nevada over the past four decades, CSSI has continued to work tirelessly to distance our company from the competition. Our fully licensed, bonded, and insured agency has earned certifications that our competitors do not hold. We have also invested in everything from proper training for our security guards to professional patrol vehicles.

CSSI has even doubled down on our commitment to developing effective security protocols quickly for every single client. We are dedicated to becoming a one-stop shop for those seeking high-quality armed and unarmed security services.

Serving Commercial Property Owners, Event Planners, and Government Agencies

At CSSI, we have extensive experience catering to many clients across various industries. Our team, which features vetted security guards, managers, and support staff, collaborates with companies of all sizes to develop customized security solutions tailored to their specific commercial properties.

These companies routinely count on us to safeguard:

Construction sites
Schools
Hotels
Healthcare facilities
Warehouses
Movie shoot locations
And more

CSSI also goes the extra mile by offering additional armed and unarmed security services, such as arranging for security officers, protection officers, and/or off-duty law enforcement officers to watch over events and providing personalized executive protection for VIP clients.

CSSI has consistently delivered outstanding security services over the years, earning the trust of even government agencies, which have sought our assistance. The Department of Transportation (DOT), the Department of Agriculture (USDA), and other government agencies have all trusted us to set them up with our stellar services.

Separating Ourselves From the Competition Since the Beginning

From the start, CSSI has always strived to stay one step ahead of our competition. Initially, we achieved this by responding to our clients more quickly than our competitors could and helping them land on speedy, surefire solutions to their security-related issues.

Although much has changed about the way we do business over time, CSSI still constantly searches for small and big ways to stand out in the crowded private security industry. Here are just a few of the traits that differentiate us from other security agencies in the present day:

We’re driven: Whether you need us to provide security services around the block, on the other side of town, across the state, or even out in the middle of nowhere, we have got you covered.
We’re scalable: We have a massive team of security personnel positioned throughout California and Nevada, giving us the unique ability to deploy a single guard to a specific location or hundreds of officers to various locations throughout an entire state.
We’re well-equipped: We have over 15 patrol vehicles (and counting!), including many that feature hybrid technology.
We’re organized: We have devised tried-and-true systems for communicating with clients, allowing us to keep them informed as we coordinate logistics, patrol properties and events, and deliver the most reliable security services around.
We’re prepared: We can respond to emergencies, as offering emergency security services has been a cornerstone of our operation since day one.

We also offer our clients competitive rates, enabling companies of all sizes to benefit from our dependable services.

Taking Our Company to the Next Level in the Near Future

CSSI is already one of the most respected private security providers among companies in California and Nevada. Still, we have our sights set on elevating the experiences that we provide to our clients moving forward.

Between now and 2030, we plan to become even more innovative, visionary, compliant, courageous, and competitive than ever before. We invite you to take full advantage of this by putting your trust in CSSI the next time you need to reserve armed or unarmed security services for a commercial property or event.
