State Agency for Technical Operations, Government security agency in Sofia, Bulgaria.
The State Agency for Technical Operations is a Bulgarian government institution responsible for technical surveillance and intelligence gathering. It operates under legal frameworks that permit the collection and analysis of communications data for law enforcement support.
The agency began in 1946 as a radio-technical service within the State Security apparatus, initially conducting telephone and mail monitoring operations. It was reorganized in 2013 to become an independent body reporting directly to the Council of Ministers.
The agency's emblem incorporates Bulgarian national symbols, featuring a shield with a lion that mirrors the official state coat of arms.
The office is located in Sofia and operates as part of Bulgaria's central government administration, making it accessible for citizens with official inquiries or administrative matters. It functions according to contemporary technical procedures and standards adapted to current requirements.
In 2013, the agency became an independent entity directly subordinate to the Council of Ministers after separating from the State Agency for National Security.
