Full-trailer theft makes headlines. Pilferage rarely does. A few cartons disappear, the seal may even look fine, and the shortage surfaces days later as a dispute between shipper, carrier, and receiver.

When people picture cargo theft, they usually imagine an entire trailer driven away from a truck stop. That happens, and it is costly. But a quieter category of loss sits alongside it: pilferage, the removal of part of a load while the rest continues to its destination. Because the truck still arrives and the paperwork still matches, pilferage is often discovered late, attributed vaguely, and written off as "shortage" rather than recognized as theft.
The overall theft environment makes this worth taking seriously. Verisk CargoNet's analysis, reported in January 2026, estimated roughly $725 million in U.S. cargo theft losses in 2025, an increase of about 60% over the prior year, with an average loss of around $273,990 per reported event. Pilferage events are typically smaller than full-load thefts, but they are also more likely to go unreported, which means their true cost is hard to see in any dataset.
Pilferage clusters around the moments a load is stationary and less observed: unsecured drop yards, long stops near highway exits, overnight parking, cross-dock transfers, and unplanned detours. It can involve outside thieves, but it can also involve people with legitimate access, which is exactly why process controls alone rarely solve it. The common thread is time and opportunity: a door that can be opened, and a window in which nobody is watching.
The single most useful piece of information in a pilferage investigation is when and where the cargo doors were opened. Real-time door sensors provide that directly. Paired with location and a planned route, each door event can be compared with where the vehicle is supposed to be. An opening at the consignee's dock is expected. An opening at 1:40 a.m. in a truck stop lot, two hours before the scheduled delivery, is not, and it can trigger a response while the vehicle is still there.
None of these is decisive alone. Together, they narrow a shortage from "somewhere between origin and destination" to a specific time, place, and event.
A door sensor that reports every opening will produce a lot of routine events. If every one becomes an alert, dispatchers stop reading them. Sentrick Cargo applies behavioral intelligence to this problem: it learns what normal looks like for a lane, schedule, and set of stops, then reads each event against that baseline and expresses the result as a clear BSIP status: Safe, Caution, Alert, Danger, or SOS. Expected stops stay quiet. Unexpected openings in unexpected places rise to the top.
Pilferage succeeds because it hides inside ordinary deliveries and leaves ambiguous evidence. Closing that gap means knowing, in real time, when a load was opened and whether that moment made sense. With door events, route context, and dwell monitoring working together, a mysterious shortage becomes a specific, actionable event, and often one you can stop before the truck leaves the lot.
