The FBI's network for sharing so-called 'suspicious activity' information within the Bureau and with the Department of Defense is called Guardian. FBI maintains a separate system for state and local law enforcement suspicious activity reports called eGuardian. According to a February 2015 request for information posted on the Federal Business Opportunities website, the FBI plans to expand its Guardian system in 2015 to include 'Top Secret' information, and integrate its case management system (called 'Sentinel') with the Guardian applications.

The integration of a non-criminal intelligence information database, Guardian, with the records in Sentinel, which contains the FBI's predicated investigations, could spell trouble for civil liberties and public safety. Suspicious activity reports have repeatedly been shown to largely contain useless, often racially or religiously biased information. Not once has information derived from a 'suspicious activity report' been publicly linked to a succesful counterterrorism investigation, or otherwise proved useful.

The relevant portions of the FBI's request for information are posted in full below:

The Guardian Program is part of the FBI’s collaborative Enterprise Threat Management System which allows the intake, assessment, investigation, de-confliction, analysis, and sharing of tips, leads, and suspicious activities across multiple Federal, State, Local, and Tribal organizations spanning multiple security enclaves.  The Guardian Program consists of two major operational elements; the Guardian application and the eGuardian application.  The Guardian application resides on the FBI’s Secret network for the use of FBI agents and analysts, Task Force Officers, as well as the Department of Defense and United States Cyber Centers through a connection to SIPRNET.  eGuardian is an application which provides appropriate law enforcement authorities the means to file suspicious activity reports and query the reports database for information on suspicious activities relevant to their jurisdictions.  eGuardian resides on the FBI’s Unclassified network.  Incorporation of a Top Secret component to the Guardian Program is planned for fiscal year 2015.

The Guardian applications will be integrated with the FBI’s Sentinel application.  Sentinel is the FBI’s next-generation information and case management system which was deployed on July 1, 2012. It replaced the Automated Case Support System, which was a paper-based case management system that utilized an electronic workflow with enhanced data-sharing capabilities.
