Which organization might employ the Top Secret Control Officer (TSCO)?

The National Security Agency (NSA) is indeed known for employing Top Secret Control Officers (TSCO). The TSCO position is essential in managing classified information and ensuring proper handling of top-secret materials within the organization. The NSA, as a key player in signals intelligence and information assurance, has a significant need for personnel who can oversee and control classified information access.

While other agencies such as the Federal Bureau of Investigation, the Central Intelligence Agency, and the U.S. Department of Homeland Security also deal with classified information and have their own security personnel, the term "Top Secret Control Officer" is specifically associated with the types of security management practices the NSA employs to protect its sensitive operations. This role ensures compliance with rigorous federal guidelines on handling classified materials, which is a primary responsibility within the NSA's operational framework.
