When your fire protection system goes offline, most fire codes require a trained fire watch on site — and skipping it can mean shutdowns, failed inspections, and serious liability if something goes wrong.
Guardian National Security keeps Los Angeles properties compliant and protected during exactly those moments: sprinkler outages, hot work, system repairs, and construction phases where fire safety is temporarily down. Our BSIS-licensed guards walk scheduled patrols, watch for hazards, keep detailed logs for your records, and are trained to act immediately if a fire starts.
Systems can fail with little warning, so we dispatch trained, documented fire watch guards within hours of your call.

Every hour a production loses is money off the budget — and a security problem can cost you several. An unsecured perimeter, a gear theft overnight, or an unauthorized visitor mid-take can stall an entire day of shooting.
Guardian National Security keeps Los Angeles productions running on time. We lock down the perimeter before call time, guard equipment and vehicles overnight, and manage access so only the people who belong on set get through. Our guards understand production pace and work with your team, never in the way of it.
Every guard is BSIS-licensed, trained under retired police officers, and GPS-tracked shift to shift. Armed or unarmed, on location or on the lot, day or night.

No two properties carry the same risk — a nightclub at 2am, a gated estate in the hills, and a downtown office tower each need something different. A one-size-fits-all security plan copied from another client will always leave gaps.
Guardian National Security builds every plan from the ground up. It starts with a free on-site walk-through, where we map your property, identify the vulnerabilities, and set post orders and schedules made specifically for your site. Nearly 30 years across Los Angeles County means we already know what your kind of property needs.
Every guard is BSIS-licensed, trained under retired police officers, and GPS-tracked shift to shift. Armed or unarmed, one guard or a full team — built around you.

A warehouse holds inventory, equipment, and loading access all in one place — which makes it a prime target for theft, especially after hours when the docks go quiet.
Guardian National Security protects Los Angeles warehouses and distribution centers with guards who control access points, monitor loading docks, verify deliveries and departures, and keep a visible presence that stops shrinkage and trespassing before they start. We build coverage around your operation — single shift, around the clock, or patrol-based across a large facility.
Every guard is BSIS-licensed, trained under retired police officers, and GPS-tracked shift to shift — so you get documented proof your facility was covered, every shift.
