The NSI's headquarters is in 1 Segunbagicha, Dhaka, Bangladesh. The NSI is the leading body of the Government of Bangladesh in the field of internal security, counter terrorism, counter intelligence and foreign intelligence. NSI is the largest among the intelligence agencies in Bangladesh, the others being the Directorate General of Forces Intelligence (DGFI), SB, CID, PBI and intelligence directorates of armed and paramilitary forces. The agency stands under the direct authority of the Prime Minister of Bangladesh.

Being the only independent civilian intelligence agency in Bangladesh, the NSI's principal activities are gathering information about foreign governments, individuals, corporations, political parties, different religious groups; counter-terrorism, counter-intelligence, political intelligence, and giving protection to the VIPs & VVIPs are among its major functions.
