Restricted party screening software: What to know when considering options

Restricted party screening software is an important compliance tool that automatically checks the individuals, businesses and government entities a company trades with against official lists of sanctioned, denied or restricted parties.

There are many such lists around the world, with some of the largest and most relevant being those published by authorities such as the US Office of Foreign Assets Control (OFAC), the US Department of Commerce, the EU and the UN Security Council. These cover both financial sanctions and export control restrictions.

The software compares customer, supplier and partner details against thousands of entries, flagging potential matches for review before a transaction proceeds. Beyond simple name matching, modern tools account for aliases, spelling variations and ownership links, helping firms uncover hidden connections to restricted parties. It automates a process that would otherwise require slow, error-prone manual research.

Restricted party screening is particularly important in situations such as onboarding new customers or suppliers, exporting controlled items or those defined as 'dual-use', arranging cross-border payments or when entering unfamiliar markets.

Getting these checks wrong can lead to severe consequences. Under US law, for example, sanctions rules carry strict liability, meaning a firm can be penalized even when a breach was unintentional. 

Civil penalties for a single violation of the International Emergency Economic Powers Act reach the greater of $377,700 or twice the value of the transaction. In the case of willful violations of sanctions lists or export controls, the cost of noncompliance escalates further, potentially exposing individuals to criminal prosecution, fines of up to $1 million and up to 20 years in prison.

Beyond the direct financial hit, firms risk losing export privileges, damaging hard-won commercial relationships and eroding the trust of regulators and partners. Effective screening keeps these risks contained before they escalate.

Without dedicated software, restricted party screening becomes a demanding task that can introduce a range of risks. Common challenges include:

• A vast list landscape: There are more than 1,300 sanctioned party lists worldwide, with over 140 in the US alone, spread across agencies such as the Commerce, State and Treasury Departments.
• Frequent updates: These lists change all the time, with names being constantly added and removed. OFAC alone may revise its lists several times a week, so a name cleared yesterday may be flagged today, or vice versa.
• Complex and hidden ownership: Under OFAC's 50 percent rule, an entity is blocked when sanctioned parties own half or more of it, individually or combined. However, it is up to firms to make this determination for themselves. Untangling ownership can mean tracing layers of intermediaries, shareholders and opaque registries across jurisdictions to identify the true interested parties.
• Common names and aliases: Shared names, transliterations (especially those from non-Latin scripts) and deliberately used aliases make genuine, exact matches hard to determine.
• False positives and negatives: Manual checks throw up large volumes of false positives: innocent matches that tie up staff and slow legitimate trade. More costly still are false negatives, where a genuine restricted party slips through undetected.
• The need for auditable records: Regulators expect firms to demonstrate that screening was carried out. For instance, OFAC now requires transaction records to be kept for at least ten years, so a clear, defensible audit trail is essential, which can be difficult to achieve with manual or ad-hoc processes.
