Solution · Sanctions Screening

Real-Time Sanctions Screening Against Every Major List

One Constellation screens every customer and counterparty against OFAC, UN, EU, UK HMT, MAS, AUSTRAC and 80+ other sanctions and watchlists — in real time, with fuzzy matching that catches what literal screening misses, and false-positive rates that don't drown your team.

The Challenge

Sanctions Screening Without Burying Your Team in False Positives

Sanctions screening is non-negotiable. Every regulated financial institution must screen customers and counterparties against domestic and international sanctions lists — at onboarding, periodically, and in real time as lists update. Get it wrong and the penalty is measured in eight or nine figures.

Get it right and the operational cost is buried in false positives. Literal name matching produces alerts for every "Mohammed Ahmed" in your customer book. Manual list management leaves windows where a newly designated entity sits unscreened. Audit trails fragmented across spreadsheets and email don't survive a regulatory exam.

One Constellation handles sanctions screening as a continuous, real-time service — not a batch process that runs overnight. Every list is updated within minutes of publication. Every screening event is logged with the exact list version, match score and analyst disposition — exportable in the format your regulator expects.

How It Works

Designed Around the Operational Reality of Modern Compliance Teams

What happens in production

Customer and counterparty records are screened the moment they enter your system, then continuously re-screened against every list update. Matches are scored, prioritised and dispositioned in a unified case interface — with full screening history, list version and reasoning preserved for audit.

What you stop doing manually

No more overnight batch jobs that miss intra-day designations. No more compliance teams chasing list updates manually. No more analysts re-keying alerts into separate case-management systems. One workflow, one source of truth, one auditable trail per customer.

A sanctions hit is only valuable if your team gets to it before the transaction settles — and only defensible if you can prove to a regulator exactly what list, what version and what reasoning produced the decision.

Sanctions Screening, Native to the One Constellation Stack

Sanctions screening doesn't exist in isolation. It's wired into KYC onboarding, customer risk assessment, transaction monitoring and SAR/STR reporting — one source of truth across every event in the customer lifecycle.

🔗
Integrated With
Onboarding · Portal · Transaction Monitoring

Because sanctions screening shares the same customer record, risk score and case history as the rest of the platform, a hit doesn't disappear into a siloed system. It triggers the appropriate EDD workflow, updates the risk score and surfaces in the next periodic review automatically.

Customers running the full One Constellation stack don't manage sanctions screening as a separate tool — it's a continuous capability of their compliance operating system, reflected in every customer view and every regulator-facing report.
