# Best Security Guard Companies in Los Angeles: How to Choose By [Great America Security Team](https://greatamericasecurity.com/about.php) · Updated October 10, 2026 · 8 min read **What this guide covers** - [How we evaluate companies](#criteria) - [License check (BSIS)](#license) - [Services compared](#services) - [Cost factors](#cost) - [Red flags](#redflags) - [Our recommendation](#recommendation) The best security guard companies in Los Angeles are licensed by BSIS, carry liability insurance, provide GPS-verified patrol reporting, and can deploy trained armed or unarmed officers. Compare licensing, supervision, reporting and contract terms before you hire. ## How We Evaluate Security Guard Companies Choosing a security provider is a decision about risk, not just price. We recommend evaluating a company on five things: licensing, insurance, supervision, reporting, and the quality of its officers. A low bid means little if guards are untrained, unsupervised, or uninsured. - **Licensing:** the company must hold a valid California BSIS Private Patrol Operator (PPO) license. - **Insurance:** general liability, workers' compensation, and bonding. - **Supervision:** field supervisors who check posts, not just a phone number. - **Reporting:** GPS-verified patrols and Daily Activity Reports (DAR). - **Officers:** background checks, drug screening, and site-specific training. ## License Check: Verify the BSIS PPO Number California requires any company that provides security guards for a fee to hold a Private Patrol Operator (PPO) license from the Bureau of Security and Investigative Services (BSIS). You can verify a license number on the BSIS public lookup. A company that will not share its PPO number is a red flag. Great America Security is licensed in California and serving Southern California since 2003. Ask us for our PPO number and certificates of insurance before you sign. ## Security Services Compared The right provider should offer a range of services so your plan can scale as your needs change. Most Los Angeles properties combine more than one service type: - [Armed security guard services](https://greatamericasecurity.com/Services/armed-security-guard.php) for high-risk or high-value sites. - [Unarmed security guard services](https://greatamericasecurity.com/Services/unarmed-security-guard.php) for access control and deterrence. - [Fire watch security](https://greatamericasecurity.com/Services/fire-watch-security-guard.php) when alarm or sprinkler systems are offline. - [Mobile patrol](https://greatamericasecurity.com/Services/bike-and-golf-cart-security-guard.php) for large or multi-building properties. - [Standing guards](https://greatamericasecurity.com/Services/standing-security-guard.php) for lobbies, entrances, and events. ## Cost Factors to Compare Security pricing in Los Angeles varies by armed versus unarmed, hours per week, property risk, and contract length. Rather than chasing the lowest hourly number, compare what each quote includes: supervision, reporting technology, uniforms, and insurance. ## Red Flags to Avoid Be cautious of providers that offer a rate far below market, cannot produce a PPO license or insurance certificate, send guards without written post orders, or have no supervisor on call. Unlicensed or uninsured coverage exposes your business to serious liability. ## What to Compare When Hiring FactorWhat to askLicenseBSIS PPO number + verificationInsuranceLiability, workers' comp, bondingSupervisionField supervisors + 24/7 dispatchReportingGPS patrol logs, DAR, incident reportsTrainingBSIS guard card + site-specific post ordersContractMonth-to-month vs long-term **Our recommendation** For most Los Angeles businesses, the best choice is a licensed, insured provider that combines trained officers with GPS-verified reporting and real supervision.
