How to monitor sanctions compliance
Monitor sanctions compliance with automated screening logs, weekly reviews, and real-time alerts tied to every transaction decision.
TL;DR
TL;DR: Use automated screening logs, weekly reviews, and real-time alerts to monitor sanctions compliance. An API that records each ALLOW or BLOCK decision gives you the audit trail for free.
Why monitoring matters as much as screening
A one-time screening check is not a compliance program. OFAC designations change, counterparties change, and the SDN List is updated regularly. Without monitoring, a counterparty that was clean yesterday may be designated today. Ongoing monitoring is what turns a point-in-time check into a durable control, and OFAC strict liability means penalties, starting at over $350,000 per violation, do not wait for you to notice.
What to monitor
Track every screening decision, not just the blocked ones. sanctionsai.dev returns clean (ALLOW) or flagged (BLOCK) in a single HTTP call under 100 ms, and its screening data syncs hourly from the US Treasury sdn.csv, covering 947 OFAC-listed crypto wallets and 19,218 SDN names. Logging each result gives you the raw material for reviews and regulator questions.
A simple monitoring routine
- Keep a machine-readable log of every screening call and result.
- Review flagged matches weekly and document the resolution.
- Set alerts so a new designation triggers immediate re-screening of existing counterparties.
Compliance is a loop: screen, log, review, and re-screen when the list changes.
Treat the log as the program's memory: when a regulator asks why a transaction was allowed, the recorded decision is the answer.
