Produce trucks at the Mariposa and DeConcini crossings

Nogales runs on cross-border truck traffic. Its commercial crossing, the Mariposa port of entry, is one of the busiest in the country, while DeConcini handles passenger vehicles and daily crossers and the Morley gate is for pedestrians. Together, Nogales' ports of entry handled 408,584 northbound truck crossings and $33.7 billion in trade in 2025, according to the Greater Nogales-Santa Cruz County Port Authority, with fresh produce from Mexico the third-largest import category at $2.8 billion behind motor vehicles and electrical apparatus. More than 100 growers and distributors keep warehouses and cold storage in the city, and I-19 carries that freight north toward Tucson and I-10.

That volume of trucks and trailers moving through a single border city is itself the exposure: produce trailers and empty chassis stage in yards between loads, often overnight, and a loaded reefer trailer left unattended is worth more to a thief than most cargo elsewhere in the state. Local trade officials have reported record freight traffic through the ports in recent years, and infrastructure work, including a feasibility study for modernizing the DeConcini crossing, is underway to keep up with it.

Sigma's agents watch a Nogales yard live, 24 hours a day, 365 days a year, so a trailer staged overnight isn't left unwatched between crossings. AI person and vehicle detection flags anyone near the fence line or the trailers after hours, an agent checks the footage, gives a live, instant talk-down through the site's speakers and calls police and your contacts, then sends over video clips and a written report. Yard Operations adds visual seal checks on video for outbound trailers, alongside truck and trailer logs; the physical seals and border paperwork stay with your team.
