If your business experiences a payment card data breach, engaging a PCI Forensic Investigator (PFI) quickly is essential. These are highly trained professionals authorised by the PCI Security Standards Council (PCI SSC) and the global card brands to investigate cardholder data compromises and determine what went wrong.
PFIs bring a mix of deep technical expertise and regulatory understanding. They work with merchants, banks, and card brands to identify how an incident occurred, what data was exposed, and what actions the impacted organisation must take to contain and remediate the issue. In some cases, their findings also support law enforcement investigations.
What Is a PCI Forensic Investigator?
PFIs are not general forensic consultants. They’re approved by the PCI SSC to handle investigations involving potentially compromised cardholder data. Each PFI must meet strict qualification requirements, and their work follows a standardised process recognised by banks, the card brands, and payment networks.
The investigator’ job is to get clarity on the situation: how attackers gained access, what systems were involved, and how far the compromise went. Their reports help affected parties make informed decisions, assess impact, identify card data (including sometimes sensitive authentication data, and personal identifying information and reduce future risk.
Stratica Australia is listed as a PFI firm by the PCI Security Standards Council and we have a team of Senior Forensic Investigators based in Melbourne, Sydney and Singapore.
When to Engage a PFI
Typically, a merchant is instructed to bring in a PFI by their acquiring bank or a card brand when there’s evidence—or strong suspicion—of a cardholder data compromise. This might happen after suspicious activity is detected in your environment or if law enforcement or card networks flag potential fraud linked to your business.
In most cases, acting quickly is not optional. Delays can lead to further exposure, make forensic work more difficult, and increase regulatory pressure.
What to Expect During a PFI Investigation
A PFI-led investigation is structured and methodical. It begins with a briefing and evidence preservation, followed by detailed analysis to determine the root cause of the breach. The process typically includes:
- Identifying how the attack occurred and which systems were affected.
- Assessing how much cardholder data may have been exposed over what period.
- Recommending corrective actions to address security gaps.
- Reporting findings to stakeholders, including acquiring banks and card brands.
How to Work Effectively with a PFI
Being prepared makes a significant difference in both the speed and success of an investigation. Some key steps:
- Don’t alter systems suspected of being compromised until the PFI gives the green light. Leave them as they are.
- Preserve logs and evidence—this is critical for understanding what happened.
- Document your timeline of events and any actions taken before the PFI was engaged.
- Ensure access to key systems, personnel, and environments so the PFI investigator can work efficiently.
PFIs are there to help you understand the incident and recover with confidence. Treating them as a partner—not just a compliance requirement—goes a long way.
Preparation Beats Panic
Smart organisations don’t wait for an incident to figure out their plan. Having a retainer relationship with a trusted PFI firm, reviewing your incident response playbook, and knowing how to escalate when something goes wrong can save precious time and reduce the impact of a data breach. Knowing who to contact and how to quickly engage a PFI ahead of something happening really makes sense! Maybe consider having an on call PFI retainer arrangement?
