Attribution

Sigeel contains public sector information made available under the licences listed above. Attribution is provided in accordance with those licences. Nothing in this attribution implies endorsement by any government, regulator, or public authority of Sigeel, its products, or its services.

Where a licence requires attribution, the required form is the source name as shown on this page. Customers who redistribute Sigeel's responses should retain the list.source field, which identifies the originating list for each match.

Lists we do not use

Sigeel does not currently include the United Nations Security Council Consolidated List or the Swiss SECO sanctions list. Both are distributed under terms that restrict commercial redistribution without explicit permission or a paid licence. If your compliance obligations require screening against either list, contact us — we can discuss whether that coverage is feasible.

Data provenance for customers

Every /screen response includes metadata about the exact list build that was checked, in the list field: the source name, a Unix timestamp of when the local index was built, and the total entity count at that build. Combined with the Ed25519 signature, this lets you prove months later which version of which list was screened against, and that the response was not altered.
