The Maritime domain supports the effective understanding of anything associated with the global maritime realm that could impact the United States' security, safety, economy, or environment. NIEM facilitates this understanding through effective, timely sharing of vital, secure information among many key partners by representing vessels, people, cargo, and maritime locations and activities.


The U.S. Navy and the U.S. Department of Homeland Security are currently partnering to sponsor the Maritime domain and maintain the exchange model. Other federal agencies, as well as local and state law enforcement agencies in port cities and coastal regions, are also stakeholders in managing this domain.
