Fatture e corrispettivi is the Italian government portal used to review tax data from electronic invoices and receipts, check stamp-duty calculations, and manage related payments or adjustments. In practice, it sits between the invoice exchange flow and the taxpayer’s accounting records, turning legal compliance into a data-management process.
From a cyber-security perspective, the portal matters because its records affect money, compliance, and audit evidence. If an attacker changes invoice metadata, reuses credentials, or tampers with uploads and exports, the result can be wrong duty calculations or reconciliation drift across many documents. Defenses therefore focus on strong authentication, role separation, logging, and validation of XML and portal data against internal ERP systems. For organizations, the key risk is not only fraud but also operational integrity: a small classification error can propagate through automated workflows and create large-scale reporting problems.
