DHS Special Events Program

The DHS Special Events Program (SEP) manages the National Special Event Data Call (NSEDC), which is an annual process that relies on the voluntary participation of states and territories to collect information on events occurring in their jurisdictions. Over 40,000 events are voluntarily submitted to the NSEDC by state and local authorities each year. The primary data collection period opens the first week of August and remains open for six weeks. The SEP continues to accept event submissions throughout the year as “short notice events.” All events submitted to the NSEDC receive a Special Events Assessment Rating (SEAR) that is applied using a risk-based analytical approach.

Nationwide Suspicious Activity Reporting (SAR) Initiative (NSI)

The Nationwide Suspicious Activity Reporting (SAR) Initiative (NSI) is a joint collaborative effort by DHS, FBI, 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.

CBRNE Program
