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.
