Frequently Asked Questions
California has some of the strictest armed security guard requirements in the nation. All of our armed officers hold a valid California Bureau of Security and Investigative Services (BSIS) firearms permit, which requires completing a certified 14-hour firearms training course, passing a live-fire qualification exam, and undergoing a thorough criminal background check. Beyond the state minimum, our guards receive additional in-house training specific to San Diego County, including scenario-based drills for active threat response, liability and use-of-force legal updates, and quarterly re-qualification at local firing ranges. We also require annual CPR and basic first aid recertification to ensure our officers can provide emergency assistance while waiting for first responders.
The decision between armed and unarmed security depends largely on your risk profile, industry, and specific concerns. Armed security is typically recommended for businesses that handle large amounts of cash or valuable inventory, such as banks, jewelry stores, cannabis dispensaries, and high-end retail. It is also common for late-night establishments in high-foot-traffic areas like the Gaslamp Quarter or Pacific Beach, as well as for executive protection, construction sites with expensive equipment, and properties with a prior history of violent incidents. Unarmed security is often sufficient for office buildings, HOAs, schools, and low-traffic retail. We conduct a free on-site risk assessment for every potential client to help you make an informed, unbiased recommendation based on your actual threats—not just upselling a service you don’t need.
Our philosophy is that a firearm is a last resort, not a first response. Every armed officer is extensively trained in verbal de-escalation techniques, conflict resolution, and crowd management before they ever draw a weapon in a real-world scenario. In crowded public spaces like parks, transit centers, or festivals, our guards prioritize maintaining a visible but calm presence, using communication to defuse tension, and only escalating force when there is an immediate, credible threat of death or serious bodily harm. We also carry liability insurance that exceeds state minimums and maintain strict post-order protocols that outline exactly when and how force may be used. Every use-of-force incident—no matter how minor—requires immediate reporting, supervisor review, and a full internal investigation to ensure compliance with both Treston policy and California law.
