Today, the Society has over 5,000 members in the United States and overseas including representatives from NATO countries. Within the U.S., members come from the Department of Energy, Department of Defense, Department of State, National Aeronautics and Space Administration, Federal Bureau of Investigation, National Security Agency, General Accounting Office--virtually every Federal agency that deals with classification--and from the civilian contractors who work with these agencies. As the Society has grown over the years, its focus has also expanded. NCMS now provides professional development for its members in the field of classification management, information security, personnel security, computer security, operations security (OPSEC), facility security, and technology security.
