Overview 

The Law Enforcement Information Sharing (LEIS) Service is a standards-based data 
exchange platform designed to aid investigations by allowing DHS and other law 
enforcement agencies to share pertinent, legally sharable case information more rapidly 
and extensively. The LEIS Service offers investigators a more efficient, automated 
system for obtaining information and helps to more quickly identify non-obvious 
relationships, patterns and connections between individuals and organizations. The 
LEIS service promotes DHS compliance with information exchange technical standards, 
including the National Information Exchange Model (NIEM) standards for justice 
information, Department of Justice (DOJ) and DHS standards for law enforcement 
information, and the Federal Intelligence Community (IC) standards for intelligence 
information. 

 

The benefit of the LEIS service and its law enforcement information sharing solution is it 
expands and appropriately engages all necessary participants at all levels: federal, 
state, local, tribal, private sector and international. Law enforcement information is often 
the most critical information for both solving cases as well as abating threats. Certainly 
the full fusion of law enforcement information contributes to strategic, tactical, and 
operational mission success and is critical within the investigative process. The 
solutions currently being driven by DHS are geared toward accommodating the needs 
and capabilities of the end user. 

 

DHS has partnered with the International Justice and Public Safety Network (Nlets) and 
the National Data Exchange (N-DEx) to provide U.S. and Canadian law enforcement 
agency subscribers the ability to access DHS sensitive but unclassified law enforcement 
information. This is accomplished this by providing connectivity between the DHS Law 
Enforcement Information Sharing (LEIS) Service and the Nlets or N-DEx computerized 
network(s) for transmitting automated criminal justice information.
