The eGuardian System (eGuardian) is a web-based platform where federal and state law enforcement entities can collaborate, coordinate, and deconflict investigative activity. eGuardian allows other federal agencies, state, local, tribal, and territorial law enforcement (FSLTT) entities, the Department of Defense, and Fusion Centers to document, share and track potential threats, suspicious activity, and cyber, counterterrorism, counterintelligence, or criminal activity with the FBI and with each other.
