FatturaPA is the standardized XML format used to send electronic invoices to Italian public administrations. It defines a strict document structure for invoice data, recipient details, tax fields, and correction documents, so systems can validate and route the file in a controlled workflow.
In cyber security, FatturaPA matters because structured business documents are part of the organization’s trust boundary. A tampered XML file, a forged status message, or a misclassified rejection can cause accounting errors, broken audit trails, or fraudulent payment attempts. Defenders rely on schema validation, signature and integrity checks, receipt logging, and immutable archives to prove what was sent, accepted, rejected, or corrected. In practice, the security challenge is not only keeping systems online, but preserving document authenticity and traceability across the full billing chain.
