The article addresses cooperation between the internal surveillance and control structures of state-owned companies, and intelligence bodies of the Civil-Military Dictatorship of 1964. Particular cases of three state-owned companies are discussed: Petrobras, CSN, and Itaipu Binacional. Based on the set of information available, in various bibliographic sources, a comparative exercise is carried out. The article concludes that such surveillance structures, under the supervision of the National Information Service (SNI), constituted important control and surveillance devices, with the capacity to monitor union, political, social movements, and individuals in wide areas of the national territory.
