A procurement restriction is a rule that limits which products or services an organization may purchase or renew. It can apply to a named supplier, its affiliates, or technology incorporated into third-party products, depending on the rule’s scope.
In cybersecurity, these restrictions help organizations manage supply-chain risk and meet legal or policy requirements. Applying one may require teams to review purchasing records, software inventories, supplier disclosures, and contracts to identify affected tools-including hosted services or components embedded in other products. Clear scope and vendor documentation matter: an inventory can reveal where a product is used, while the restriction’s terms determine whether it must be removed, avoided in new purchases, or handled another way.
