Restructuring
The SBU is a successor of the Ukrainian Soviet Socialist Republic's Branch of the Soviet KGB, keeping the majority of its 1990s personnel. Since 1992, the agency has been competing in intelligence functions with the intelligence branch of the Ukrainian Ministry of Defense. Despite this, a former Military Intelligence Chief and career GRU technological espionage expert, Ihor Smeshko, served as an SBU chief until 2005.
In 2004, the SBU's Intelligence Department was reorganized into an independent agency called Foreign Intelligence Service of Ukraine. It is responsible for all kinds of intelligence as well as for external security. As of 2004, the exact functions of the new service, and respective responsibilities of the Foreign Intelligence Service of Ukraine were not regulated yet.
On November 7, 2005 the President of Ukraine created the Ukraine State Service of special communications and protection of information, also known as Derzhspetszvyazok (StateSpecCom) in place of one of the departments of SBU and making it an autonomous agency.
The SBU subsumed the Directorate of State Protection of Ukraine (Ukrainian: Управління державної охорони України), the personal protection agency for the most senior government officials, which was the former Ninth Directorate of the Ukrainian KGB.
