Intersec PCI Forensic Investigator is a certified incident response service specializing in payment card industry data breaches. The service is provided by one of approximately a dozen PCI Forensic Investigators (PFI) certified in the USA by the Payment Card Industry Security Standards Council. The service conducts forensic investigations to determine whether a breach of cardholder data occurred, what information was compromised, and the root cause of the incident. Investigations include analysis across multiple domains including threat analysis, endpoint examination, DNS review, network assessment, application and web application analysis, and firewall and log review. Beyond investigation, the service provides remediation planning and implementation to address vulnerabilities that led to the breach. The service is positioned as a remediation specialist within the PCI industry, with other PFI firms reportedly recommending Intersec for remediation work following their own investigations. The service operates as part of a broader Digital Forensics and Incident Response (DFIR) practice and works across all industries. Investigation findings are used to support breach response activities, consumer notification, and civil or criminal investigations related to the incident. The service emphasizes the importance of consulting with a PFI before taking action during a suspected breach to preserve evidence integrity.
