Sanctions & watchlists
OpenSanctions
Consolidated, open database of sanctions targets, politically exposed persons and other watchlisted entities.
Good for a fast first pass across many regimes at once. It is not a substitute for checking the authoritative list that actually binds you.
Aggregates dozens of official sources into one searchable dataset with stable identifiers, which makes it far quicker than checking each regime in turn.
Use it to find candidates, then confirm against the source list. For a Crown Dependencies compliance obligation the binding list is the one your own jurisdiction gives effect to. Treat an OpenSanctions hit as a prompt to go and read that list before you record anything as a finding.
