An elenco fornitori is the approved supplier list used to decide which vendors, services, or products are eligible under a program or procurement scheme. In a cloud or cybersecurity voucher process, it acts as an eligibility filter: if a provider is not on the list, the buyer may not be allowed to purchase from it, even if the service is technically suitable.
For security teams, this matters because approved-vendor lists shape the trust boundary before any system is installed. They can reduce risk by limiting purchases to vetted suppliers and compliant offerings, supporting supply-chain assurance and simpler audits. At the same time, defenders should verify that the list is current and that the chosen service matches the exact listing, because mismatched descriptions, expired approvals, or incomplete paperwork can block a valid request. In attacks, criminals may try to impersonate approved vendors or exploit confusion around supplier names and categories.
