Sirius Core

Sirius Core overview

The compliance engine. Screening, scoring, and clearing on primary regulatory data — exposed as an API surface.

Sirius Core screens every payment on the rail before funds move — sanctions, PEP, and risk scoring against primary regulatory data: the sources that regulators themselves publish and update, built in-market and kept continuously current.

Unlike most payment platforms, Onzo exposes compliance as a first-class API surface. Screening decisions are objects you can retrieve, display to your operations team, and hand to your auditors.

Screening decisions

Every decision, with its reasons, as a retrievable object — `oz_scr_`.

Held for review

The playbook for exception handling — what to show, what to tell your users, and how reviews resolve.

Standalone

Sirius Core is available standalone. Banks and payment institutions can license the engine — screening, scoring, and monitoring on live regulatory data — without touching the settlement layer. Contact us for institutional access.

Data posture

Primary sources only — regulatory and sanctions screening runs against official sources, ingested directly
Updated continuously — not on a vendor refresh cycle
Data residency in-region — customer and transaction data is processed and stored in-region
Full audit trail — every screening decision is logged, timestamped, and retrievable
