Security Guard Company
San Bernardino County

San Bernardino County is the largest county in the continental United States and its security demands match its scale. From the logistics corridors of the Inland Empire to the High Desert communities of Victorville and Apple Valley, every part of this county presents its own unique protection challenges. Guardian National Security has spent nearly 30 years serving Southern California properties and we bring that experience to every facility, business, and residential community we protect across San Bernardino County. Here is what sets us apart.

Active BSIS Licensing on Every Assignment

Every guard we place at your San Bernardino County property holds a current and valid California BSIS license. Our insurance coverage exceeds all state minimums so your warehouse, retail location, or residential community is fully protected from the very first shift we put boots on your property.

Hands-On Training from Retired Law Enforcement

Our guards do not just pass a basic certification. They complete training led by retired police officers who bring genuine field experience into every session. That background gives every guard assigned to your San Bernardino County property the professional judgment to handle access issues, disturbances, and emergencies correctly and within the law every time.

Full GPS Verification on Every Patrol

We track every guard movement across your San Bernardino County property using Detex GPS equipment on every shift we work. Whether your site is a distribution center in Ontario, a retail strip in Fontana, or a residential community in Victorville, you receive documented proof that your coverage was completed exactly as planned with no gaps.

Built Around the Inland Empire’s Demands

San Bernardino County runs on logistics, manufacturing, retail, and a growing residential population spread across one of the most geographically diverse regions in California. We understand the security pressures that come with operating in this environment and we build plans that address the real risks your specific location and industry face every day.

No Long-Term Contract to Get Protected

We earn your ongoing business through the quality of our work rather than a contract that locks you in. Start your San Bernardino County coverage on a trial basis and evaluate our guards, our communication, and our reporting before making any long-term commitment. We are confident the results will do the convincing.

Guaranteed to Match Any Competitor’s Price

We match or beat any competitor’s written quote for the same level of licensed guard service anywhere across San Bernardino County. Reliable professional security coverage in one of the country’s most active logistics and industrial regions should not come with a price that puts it out of reach for your operation.

Dispatch and Management Available Every Hour

Our dispatch center runs around the clock without exception. You can reach our management team at any hour of the day or night and your assigned San Bernardino County guards are always reachable when an incident or concern demands an immediate response. We never go dark.

A Proven Record Across Southern California Since 1997

Since 1997 we have protected over 10,000 properties across Southern California including nationally recognized brands like Kohl’s, Starbucks, and Bank of America. San Bernardino County businesses and property managers get access to that same depth of experience and that same standard of dependable professional protection on every shift we work.
