Open sources unambiguously identify the Federal Security Service headquarters at Lubyanka Square / Bolshaya Lubyanka in central Moscow. Official Russian government material gives the FSB address as 1/3 Bolshaya Lubyanka; U.S. Treasury sanctions material also lists Lubyanskaya Square 2, and Britannica describes the service as occupying the former KGB headquarters on Lubyanka Square.

As of February 2026, Alexander Bortnikov remains Director of the FSB. The FSB’s own leadership and biography pages identify him as director and describe him as General of the Army, while a Kremlin transcript from February 2026 still lists him in that post.

The current Russian government description assigns the FSB responsibility for national security, counterterrorism, border protection, information security, and coordination of counterintelligence across authorized federal bodies. Official FSB material also states that the service maintains contacts with 217 security, intelligence, and law-enforcement bodies in 109 states, indicating that the Moscow headquarters supports both domestic command and international liaison.

Current FSB webpages show that the Lubyanka complex hosts more than symbolic leadership offices: the service says its public reception on Lubyanka operates around the clock, and FSB subpages place licensing, certification, and state-secrets protection functions on Bolshaya Lubyanka. Separately, the Moscow and Moscow Oblast FSB directorate is officially listed at 20 Bolshaya Lubyanka, showing a concentration of central and regional FSB functions on the same street corridor.

The metadata appears to mix the Moscow headquarters with subordinate FSB educational and border-service sites elsewhere in Russia. Official FSB sources confirm a broader institutional network that includes the Academy of the FSB in Moscow, the Moscow and Golitsyn Border Institutes, and the Khabarovsk Border Institute; however, open official sources do not publicly confirm the precise mission or chain-of-command linkage for every military-unit-number placemark in this record.
