Imperial Security Bureau (ISB)

Definition

The Imperial Security Bureau (ISB) is the Galactic Empire’s intelligence and internal security apparatus.

What it does

The ISB gathers data, hunts rebel cells, monitors Imperial officers and looks for patterns in events that appear unrelated. Andor shows the agency as bureaucratic, analytical and ruthless.

Why it matters

The ISB makes the Empire feel dangerous beyond Sith Lords and superweapons. It shows how dictatorship is maintained through records, informants, surveillance and fear.
