Card Data Discovery Tool | PCI Data Security

Credit card data shows up in more places than teams expect, including support tickets, chat threads, spreadsheets, exports, logs and even GenAI prompts. Card data discovery is the ongoing process of locating cardholder data (CHD and PAN) across SaaS apps, cloud storage, endpoints and databases so you can minimize exposure and prove PCI compliance. Modern tools make this continuous, accurate and low friction through agentless, API-native scanning and inline remediation that removes sensitive data without slowing your teams. Strac adds ML and OCR detection and DSPM plus DLP visibility so you can see posture and resolve issues in one place.

Regulatory Background for Card Data Discovery Tool

PCI DSS defines how organizations must protect account data, from where CHD can be stored to how long it can be retained, who may access it and how incidents are handled. Core expectations include scoping your CDE correctly, restricting CHD storage, encrypting data in transit and at rest, logging access and responding quickly to leaks.

With PCI DSS v4.0, assessors expect stronger evidence that you can identify and control CHD outside the defined environment, not only inside it. That means continuously discovering stray CHD across collaboration tools, cloud buckets, email, tickets, repos and devices, then remediating or tokenizing it to reduce scope and risk. Strac provides prebuilt PCI classifiers and auditor friendly reporting that make evidence collection faster. Checkout PCI DSS Requirements for Card Data Discovery

How Card Data Discovery Tools Work

Data types and sources. Effective platforms scan text and files across email, chat, ticketing, cloud drives, wikis, data lakes, object storage, endpoints and logs, as well as integrations where PAN can transit such as CRM, support and billing. Strac covers SaaS, Cloud and Endpoints with 40 plus integrations.

Detection techniques. Start with Luhn validated regex for PAN, then improve accuracy with ML and context aware detection, OCR for images and PDFs, and archive scanning for ZIP and RAR. Strong tools normalize encodings, inspect attachments and analyze patterns such as BIN and brand formats to reduce noise. Strac focuses on low false positives so security teams can act faster.

Scanning frequency and scope. Combine continuous or near real time scanning for high risk surfaces such as support and chat with scheduled deep scans for storage systems. Auto discover new data sources and apply risk based scope so the highest impact systems receive the tightest controls. Strac supports event driven scans and scheduled jobs to match your risk profile.

Where Might Credit Card Data Reside?

• Email and Chat: forwarded receipts, support conversations, screenshots of payments
• Ticketing and CRM: pasted PANs in cases or notes, attachments with invoices
• Cloud Drives and Wikis: CSV exports, reconciliations, temporary folders, archived ZIPs
• Object Storage and Data Lakes: raw ingestion buckets, staging tables, logs
• Endpoints: desktop downloads, local cache folders, clipboard history
• Dev and Ops Tools: debug logs, test fixtures, sample payloads in repos
• GenAI and Automation: prompts, responses and workflow outputs that include CHD
• Strac integrates with tools like Slack, Salesforce, Google Workspace and AWS, which are frequent sources of accidental CHD sprawl.

Challenges and Pitfalls

Hidden or unexpected storage locations. CHD often lives in attachments, images and archives, and in back up or sync locations users forget. Require OCR and archive traversal to catch it.

Performance and resource constraints. Naive full content scans can be noisy or slow. Prefer API native, incremental scanning with event based triggers for high velocity apps. Strac’s approach reduces latency and avoids user friction.

Ensuring privacy and legal compliance when scanning. Discovery should honor least privilege, data residency and retention policies. Look for mask in place options that remediate without broad exposure.

Maintaining configuration and rules. PCI evolves, as do your systems. Choose a tool with versioned policies, prebuilt PCI DSS v4.0 updates and CI style testing for custom detectors.

Operationalizing findings. Alerts without action create backlog. Favor platforms that auto create tickets, route owners and remediate inline, and that provide clear audit trails. Strac unifies DSPM and DLP so you can see posture, findings and fixes in one console.

PCI DSS 4.0: 12.5 Requirement: Comprehensive Credit Card Discovery

The Payment Card Industry Data Security Standard (PCI DSS) version 4.0 amplifies the call for robust data discovery practices. Section 12.5.2 of PCI 4.0 mandates organizations to identify all locations where account data is stored, processed, and transmitted. This isn’t just a suggestion; it’s a requirement for compliance that extends beyond the confines of the Cardholder Data Environment (CDE) to encompass applications, system transmissions, and even file backups.

"Identifying all locations where account data is stored, processed, and transmitted, including but not limited to: 1) any locations outside of the currently defined CDE, 2) applications that process CHD, 3) transmissions between systems and networks, and 4) file backups."

🌶️Spicy FAQs

What is card data discovery and why does it matter for PCI DSS 4.0

Card data discovery is the continuous process of finding cardholder data (CHD and PAN) across SaaS, cloud storage and endpoints. It proves you can identify CHD outside the CDE, which is a sharper expectation in PCI DSS 4.0.

Where does CHD usually hide

Email threads, chat messages, support tickets, attachments, spreadsheets, ZIP archives, S3 buckets, logs and developer test data. Modern tools scan these sources across SaaS, Cloud and Endpoints.

How does a card data discovery tool detect PAN accurately

Start with Luhn validation and precise regex, then add OCR for images and PDFs and ML context signals like IIN ranges and brand patterns. This reduces false positives and finds CHD in files and screenshots.

Is cloud DLP the same as card data discovery

Cloud DLP protects sensitive data in cloud apps. Card data discovery is a focused use case that finds PAN and CHD wherever they live. Many teams pair cloud DLP with discovery to cover detection plus inline remediation.

How often should I scan for cardholder data

Use continuous or event driven scans for high risk surfaces such as support and chat. Schedule deep scans for cloud drives, object storage and archives. This mix balances accuracy and performance.

Can an agentless approach really cover everything

Agentless, API native integrations cover a large surface across SaaS and cloud without heavy installs. For edge cases on endpoints, combine scheduled scans with targeted connectors. Agentless helps teams deploy faster and avoid friction.

What features matter most in a card data discovery tool

Broad platform and file type support, prebuilt PCI rules with custom classifiers, strong false positive controls, OCR, archive scanning, risk scoring, dashboards for auditors and real remediation like redaction and masking.

How does inline remediation help with PCI compliance

Inline redaction or masking removes exposed PAN from chats, tickets and files in place. This shortens dwell time, reduces scope and creates auditable evidence that you controlled CHD promptly.

Will scanning content violate privacy rules

Choose a tool that honors least privilege, data residency and retention. Look for mask in place workflows, scoped access and detailed audit logs so discovery aligns with legal and privacy requirements.

How do I measure success for card data discovery

Track findings reduced over time, mean time to remediation, percent of high risk systems under continuous scan, auditor acceptance of reports and fewer out of scope CHD incidents.

Do we still need a CASB if we have cloud DLP

Yes. A CASB governs access and risky usage in cloud apps. Cloud DLP and card data discovery protect the data itself. Together they deliver layered defense for PCI and everyday security.

Why Strac for card data discovery
