The latest figures from U.S. Customs and Border Protection (CBP) show that May 2025 was a historic month for the border agency. In the month of May, CBP released zero illegal aliens into the interior of the U.S., seized 708 pounds of fentanyl, and a 191% year over year increase in heroin seizures.

San Ysidro Port of Entry in San Diego, California, is one of the busiest land-border crossings in the world and was the site of many of the apprehensions and seizures in May. Mariza Marin is the CBP Port Director at San Ysidro, where she leads many of the border officers responsible for the agency’s success so far in 2025.

This September, Director Marin will be on-site at IDGA’s Border Technology Summit where she will participate in a panel discussion with fellow CBP port directors. Before the summit, she sat down with IDGA to share her day-to-day duties as a port director, technologies shaping border operations, and the value of collaborating with staff at other ports of entry.

If you are interested in hearing from the officers responsible for securing U.S. borders, such as Director Marin, register for the Border Technology Summit taking place September 23-24 in San Diego, California.
