The Montana Board of Private Security Officers and Investigators, which operates through the Montana Department of Labor and Industry, regulates and licenses private investigators and private investigator trainees. As of May 2020, the Board licensed just 170 private investigators throughout the state, which means you’ll have plenty of space to forge your own career path here without bumping up against the competition too much.
