How to Choose the Best Security Guard Company in Los Angeles
With dozens of security companies operating in Los Angeles, here is what separates the best from the rest.
1. Confirm Full BSIS Licensing
California requires every security company to hold a BSIS company license and every individual guard to carry a Guard Card. Armed guards also need a BSIS Firearm Permit. Verify all licenses directly on the California Department of Consumer Affairs website before signing anything.
2. Check Insurance Levels
The minimum general liability coverage is $1 million. The best companies carry more. OnGuard carries $1.5 million. Request a current certificate of insurance and verify the policy is active.
3. Require a Physical Site Assessment
The best security company for your property is the one that has actually seen it. A proposal based on a site visit is worth far more than a generic quote. OnGuard conducts free on-site threat assessments before proposing coverage.
4. Ask About Contract Flexibility
Long-term contracts lock you in regardless of service quality. Ask specifically about minimum terms, cancellation provisions, and rate adjustment clauses. The best providers do not need to trap clients in long commitments.
5. Evaluate Supervision and Accountability
Ask how guards are supervised, how incidents are reported, and who owns your account. A dedicated supervisor — not a rotating call center — is the mark of a company that takes accountability seriously.
6. Assess Local Market Knowledge
Los Angeles is not one market. Downtown, the Valley, Westside, South Bay, and East LA each have distinct security profiles. A company with genuine local depth will provide more precise, effective coverage than one running standardized programs from a national template.
Why Hiring the Best Security Company Matters in Los Angeles
Los Angeles has one of the highest commercial property crime rates among major U.S. cities. According to FBI Crime Data Explorer statistics, LA consistently ranks in the top tier nationally for commercial burglary and vehicle theft. Choosing the best security provider — not just the most affordable or most convenient — directly affects how well your property is protected.
Key Benefits Include:
- Deterrence that measurably reduces crime incidents on your property
- Professional access control that prevents unauthorized entry
- Rapid incident response that limits damage and liability
- Documented reporting that supports insurance and legal processes
- A safer environment for employees, tenants, and customers
The real cost of choosing a low-quality provider includes not just security failures but the liability exposure from improperly licensed or supervised guards operating on your property.
