U.S. Department of Homeland Security

The U.S. Department of Homeland Security (DHS) operates dynamically across the broader Bay Area through a multi-agency network—including CBP, HSI, and the Coast Guard—to protect critical national infrastructure, enforce maritime laws, and secure international trade borders. The department coordinates complex, high-stakes security operations out of major regional transportation hubs, including the Port of Oakland, the Port of San Francisco, and regional international airports. Their unified, targeted regional presence provides the essential federal security framework and emergency response readiness required to safeguard vital supply chains, combat transnational crime, and maintain resilient waterfront commerce.
