SBInet was a program initiated in 2006 for a new integrated system of personnel, infrastructure, technology, and rapid response to secure the northern and southern land borders of the United States. It was a part of Secure Border Initiative (SBI), an overarching program of the United States Department of Homeland Security (DHS) to organize the four operating components of border security: U.S. Customs and Border Protection (CBP), U.S. Immigration and Customs Enforcement, United States Citizenship and Immigration Services, and the United States Coast Guard. DHS announced the program's cancellation on Jan. 14, 2011.
In August 2008, DHS ordered Boeing to stop SBI work along the border between Arizona and Mexico because CBP had not received the necessary permissions from the Department of the Interior. Boeing told a subcontractor that the suspension of work could last until January 1, 2009. On March 16, 2010, Homeland Security Secretary Janet Napolitano announced the DHS was diverting $50 million for the project into other efforts and that all work beyond the current pilot projects have been frozen.
