There are a range of different entities that are sanctioned, it is not just banks. There are specific financial sanctions; however, there are various entities (and named individuals) who are included in the sanctions, outside of the financial industry.
The notice from IAF is limited to entities that are sanctioned, including US, international, regional, and domestic sanctions, wherever IAF AB members and CABs accredited by them operate.
There are CABs and certified organizations in the Russian Federation that will not be impacted by the sanctions and those certifications may continue.
