Russia
Three principal successors to the Soviet KGB — the FSB (domestic), the SVR (foreign), and the GRU/GU (military) — operating under direct presidential authority with limited civilian oversight.
The Russian Federation's principal intelligence services are direct successors to the Soviet Committee for State Security (KGB), divided after 1991 into separate civilian domestic and foreign components plus the long-standing military service. The Federal Security Service (FSB) inherited the KGB's internal security mandate and absorbed signals-intelligence functions in 2003 with the abolition of FAPSI. The Foreign Intelligence Service (SVR) took over the foreign-intelligence mission of the KGB First Chief Directorate. The Main Directorate of the General Staff — formally renamed the GU in 2010 but commonly still called the GRU — continued the Soviet-era military-intelligence service that traces its lineage to 1918.
Each of the three reports directly to the President of the Russian Federation through the Security Council, and each is led by an appointee of the President. The services do not have parliamentary oversight on the model of comparable Western services; the principal external public-record judicial scrutiny — historically through the European Court of Human Rights — ended with Russia's expulsion from the Council of Europe in March 2022. The post-2014 period of operations in Ukraine, the post-2018 period of Western government attribution for cyber and direct-action operations, and the post-February 2022 invasion of Ukraine have produced an unprecedented volume of public-record material on Russian state intelligence activity.

How to read a country page
This is the institutional landscape of Russia's intelligence apparatus as it is documented in the public record. Each card above links through to a full agency profile — the service's founding date, statutory basis, jurisdiction, parent ministry, headquarters, official channels, and a structured account of role, history, and notable operations footnoted to primary sources. The agencies on this page may overlap institutionally (a foreign-intelligence service and a signals-intelligence service often share missions and personnel) and may operate against one another in counter-intelligence terms; the country page does not impose a hierarchy among them, only an inventory.
If a particular operation or scandal is what you are looking for rather than the institutional background, see the Dossiers — long-form pieces that cross agencies and countries. The methodology page documents how operations are categorised as confirmed, alleged, or disputed, and what the public record can and cannot tell us. The Lexicon defines the terms that recur across these pages — HUMINT, SIGINT, covert action, plausible deniability, station, asset, finding.
Coverage here grows as new declassifications expand what can responsibly be said about services that remain partly closed. Some agencies have full reference entries; others are stub entries pending the full treatment. Stubs are kept on the index so navigation between related services is preserved while the detailed text is written.
