Warehouse and Logistics Security in Ontario

Ontario sits at the heart of the Inland Empire logistics corridor, where I-10, I-15, and SR-60 carry freight to and from distribution centers every day. Our guards protect warehouses, truck yards, and loading docks with gate control, trailer and seal checks, and scheduled patrols of fence lines and parking areas. Every shift is documented with digital incident reports, so site managers know exactly what happened overnight.

Cargo theft and trailer break-ins are real risks in the area, so we pair guards with cameras and access logs for a clear record of every visitor and vehicle.

For shopping centers, we coordinate with property management on opening and closing routines, so stores and customers feel safe from the first shift to the last.
