Welcome to the Official LinkedIn page for the Naval Criminal Investigative Service (NCIS). #PeopleFirstMissionAlways Within the Department of the Navy, NCIS is the civilian federal law enforcement agency uniquely responsible for investigating felony crime, preventing terrorism and protecting secrets for the Navy and Marine Corps. Comprised of approximately 2000 personnel, with more than half serving as federal Special Agents, NCIS is unique among U.S. military criminal investigative organizations as it is a civilian-run agency and is headed by a civilian law enforcement professional who reports directly to the Secretary of the Navy. Today, NCIS operates in approximately 191 locations, in more than 41 countries. Given the organization's worldwide forward presence, NCIS is often the first federal law enforcement agency on the scene when U.S. interests overseas are affected. In addition to serving at major naval commands around the world, NCIS Special Agents deploy aboard all Navy aircraft carriers and with amphibious task forces. NCIS agents routinely conduct advances before U.S. Navy ships visit non-Navy ports, working with domestic and foreign counterparts to identify and mitigate security threats. NCIS also conducts protective service operations for senior naval officials and visiting dignitaries. NCIS Professional Staff personnel comprise the remaining half of our workforce and are vital to our success as an agency. They represent the backbone of our organization in mission essential areas like Intelligence, Polygraph, Forensics, Tech, Communications, Cyber, and Human Resources.
