National Intelligence Service (Bulgaria)
The State Intelligence Agency (SIA) (Bulgarian: Държавна агенция „Разузнаване“, Durjavna Agencia Razuznavane) is a Bulgarian foreign intelligence service, which obtains, processes, analyzes and provides the state leadership with intelligence, assessments, analyses and prognoses, related to the national security, interests and priorities of the Republic of Bulgaria.
The history of intelligence agencies in Bulgaria can date back to 1925 when the Law on Administration & Police (Закона за администрацията и полицията, Zakona za administratsiyata i politsiyata) & the Police Directorate of the State Security Department set up a Foreign Policy Service (външнополитическа служба, vŭnshnopoliticheska sluzhba). Foreign Policy Intelligence existed as from 1925-1990 as part of the Police Directorate (Дирекция на полицията, Direktsiya na politsiyata) which existed from 1925-1944. 
In the wake of post-communist era the foreign/external intelligence activities, formerly carried out by the First Main Directorate of the Committee for State Security, were separated and consolidated in the National Intelligence Service. Reforms in the security sector in Bulgaria began as early as 1991; the period was characterized by the deep mistrust of the successors of the Communist-era services and by dismissal of several experienced officials on political grounds. The passage from the Party-Interior-Defence architecture to the President-Prime Minister model led to a downgrading of efficiency. The National Intelligence Service was subordinated to the President:
The Kosovo War was a milestone and a turning point for the Bulgarian foreign policy and for the intelligence community because of the great amount of practical co-operation with the major NATO countries and an unusual amount of information and intelligence sharing, although no formal contact was established. Alongside military and financial intelligence reform, a Security Council, subordinated to the Prime Minister, was created with the aim of coordinating the efforts of the whole of the intelligence community. On October 1, 2015 National Intelligence Service was transformed into State Intelligence Agency with the State Intelligence Agency Act, passed by the XLIII National Assembly.
The State Intelligence Agency (SIA) is a security service, which obtains, processes, analyzes and provides the state leadership with intelligence, assessments, analyses and prognoses, related to the national security, interests and priorities of the Republic of Bulgaria. SIA is part of the intelligence community, defined in the National Security Strategy as a system of state bodies that provide information and analysis, assess the risks and threats to the national security, and plan and implement due countermeasures.
The Agency also takes part in the activities of the intelligence communities of the European Union (EU) and the North-Atlantic Treaty Organization (NATO).
SIA cooperates with the other state institutions and structures that are part of the national security system, which perform functions in the sphere of diplomacy, defence, intelligence, counterintelligence, criminal investigation, law enforcement and security.
The mission of SIA is to protect the national security and the interests of the Republic of Bulgaria, but also to support the state leadership in their efforts to fulfill the national priorities, by providing the latest and most reliable intelligence and analysis of events and developments pertaining to the national security, foreign policy, economy and the safeguarding of the constitutional order.
To this end, SIA carries out intelligence operations and obtains, stores, summarizes, analyzes and provides intelligence information.
Intelligence information is any information, obtained by the Agency about foreign countries, organizations and individuals, or Bulgarian organizations and individuals related to these, which is of significance for the national security of the Republic of Bulgaria.
Different information materials – such as reports, analyses and briefings – are prepared on the basis of the acquired intelligence information and provided to the state leadership.

Priority areas of activity
- Terrorism and other asymmetric threats
