Commercial security services protect Los Angeles offices, retail stores, warehouses, and industrial properties with licensed guards, access control, patrols, and reporting, deterring theft, vandalism, and unauthorized access around the clock.

## Property Types We Protect

Commercial security needs differ by property. Office buildings need lobby and access control; retail needs loss prevention; warehouses need perimeter patrol and dock control. We build a plan around how your property actually operates.

## Guard Duties on Commercial Properties

- Access control and visitor logging.
- Perimeter and interior patrols.
- CCTV monitoring and incident response.
- Loading dock and inventory oversight.
- Daily Activity Reports for management.
