How to integrate OFAC SDN, sectoral sanctions, and the 50% Rule into your compliance workflow.
What OFAC screening covers
The US Treasury's Office of Foreign Assets Control (OFAC) maintains multiple sanctions programs. Verifex screens against OFAC SDN, SSI, CAPTA, NS-MBS, CMIC, and PLC lists. Each match includes the specific OFAC program, sanctions basis, and entity identifiers.
