SISA Sappers:
Your Trusted PCI Forensic Investigators
Accredited by the PCI Security Standards Council, SISA Sappers deliver regulator-ready investigations with speed, precision, and compliance alignment.
PCI Forensic Investigation
When a payment card security incident occurs, the impact goes far beyond financial loss. Regulatory penalties, reputational damage, and legal exposure become immediate risks. PCI Forensic Investigation (PFI) offers a structured, regulator-approved approach to determine how the incident occurred, assess the extent of cardholder data exposure, and define corrective actions required to restore compliance.
PFI investigations are carried out under the strict guidelines of PCI Security Standards Council (PCI SSC), with validated findings reported to acquiring banks, card networks, and regulators.
When is a PCI Forensic Investigation required?
A PCI forensic investigation is mandated when a cardholder data compromise is suspected or confirmed.
Typical triggers include:
Card fraud alerts
Fraudulent emails that attempt to mislead employees or customers.
Unauthorized access to the Cardholder Data Environment (CDE)
unusual fraud patterns traced back to the merchant or service provider.
Unencrypted card data storage
accidental or deliberate retention of PAN, Sensitive Authentication Data
Malware in payment systems
including Web skimmer or memory scraping attacks.
Third-party/vendor compromise
breaches via service providers handling card data.
