How the index is organised
This index groups every intelligence agency on the site by mandate — foreign intelligence, signals & cyber, military, domestic security, law enforcement, with coordination services at the top. Within each group, entries are sorted by country and then by name. The grouping mirrors the per-country agency lists so the typology stays consistent across the site. Each card shows the agency's country of origin, its formal name and acronym, and a short editorial description. Click through to the agency page for the full reference entry — founding date, statutory basis, jurisdiction, parent ministry, headquarters, official channels, and a structured account of role, history, and notable operations footnoted to primary sources.
Coverage spans foreign-intelligence services (the CIA, SIS, DGSE, BND, GRU, SVR, MSS, RAW, and so on), domestic-security services (MI5, FBI, BfV, ASIO, DGSI), and signals-intelligence agencies (NSA, GCHQ, CSE, ASD, GCSB, FAPSI's successors). Entries marked in progress are stubs awaiting full reference treatment; they are kept on the index so the navigation between related services is preserved while the detailed text is written.
If you know the country but not the acronym, start at the Countries index. If you are looking for an operation, scandal, or theme that crosses agencies, see the Dossiers. The methodology page documents how operations are categorised as confirmed, alleged, or disputed.
