Nationwide SAR Initiative (NSI)

Nationwide SAR Initiative (NSI)

The Nationwide Suspicious Activity Reporting (SAR) Initiative (NSI) is a joint collaborative effort by the U.S. Department of Homeland Security, the Federal Bureau of Investigation, and state, local, tribal, and territorial law enforcement partners. This initiative provides law enforcement with another tool to help prevent terrorism and other related criminal activity by establishing a national capacity for gathering, documenting, processing, analyzing, and sharing SAR information.

The NSI is a standardized process—including stakeholder outreach, privacy protections, training, and facilitation of technology—for identifying and reporting suspicious activity in jurisdictions across the country and also serves as the unified focal point for sharing SAR information.

“Whether a plan for a terrorist attack is homegrown or originates overseas, important knowledge that may forewarn of a future attack may be derived from information gathered by State, local, and tribal government personnel in the course of routine law enforcement and other activities.”

- National Strategy for Information Sharing, October 2007
