PAN + CVV detectionPCI-DSS Req 3 alignmentQSA-ready evidence

PCI-DSS-aligned AI for banks, fintechs, and payment processors

Card-handling environments have spent two decades building PCI controls — and AI tools are the newest hole in the perimeter. Customer service reps draft chargeback responses in ChatGPT with full account context. Risk analysts paste fraud patterns including PANs. TeamPrompt detects and blocks card data at the browser before it lands in an AI provider's logs.

What PCI-DSS requires when staff use AI tools

Every feature designed to help your team work smarter with AI.

01

Luhn-validated PAN detection

Card numbers (13-19 digits, Luhn-valid) detected and blocked in real time. Same algorithm payment networks use — minimal false positives on order numbers or invoice IDs.

02

CVV / CVV2 / track data blocking

Sensitive Authentication Data (PCI-DSS Req 3.2) must not be stored after authorization. TeamPrompt blocks CVV patterns, magnetic stripe data, and PIN blocks from reaching AI prompts.

03

PCI-DSS Req 10 audit logs

Every detection event logged with user, timestamp, data type, AI tool, and action — directly addressing PCI-DSS Requirement 10 (Track and monitor all access to network resources and cardholder data).

04

Scope reduction architecture

Browser-side DLP keeps cardholder data within your CDE perimeter. AI tools never receive PAN, so they don't become in-scope for PCI assessment — preserving the boundary you've built.

05

Role-based for customer service vs analysts

Customer service reps need to discuss transactions; risk analysts need pattern visibility; neither needs full PAN in an AI prompt. Per-role policies enforce least privilege under Requirement 7.

06

QSA-ready evidence packages

Pre-formatted documentation maps detection events, policy configuration, and control effectiveness to specific PCI-DSS requirements for your annual SAQ or ROC assessment.

Benefits

Why card-handling teams choose TeamPrompt

Block PAN, CVV, and Sensitive Authentication Data from reaching AI providers — the modern equivalent of preventing card data on Slack
Address PCI-DSS Requirements 3 (storage), 4 (transmission), 7 (access), and 10 (logging) as they intersect with AI tool usage
Keep AI tools out of your CDE scope so they don't add audit burden to your annual ROC or SAQ
Avoid the $5,000–$100,000 per month per-merchant fines for non-compliance plus card brand sanctions
Document the AI tool controls that PCI assessors now ask about during the SAQ-A through SAQ-D engagement
Give customer service and risk teams a safe way to use AI for productivity without ad-hoc 'don't paste card numbers' policies

FAQ

Frequently asked questions

Does using AI tools put us back in PCI scope?

If staff paste PAN into ChatGPT, then ChatGPT and OpenAI's logging infrastructure arguably become in-scope systems handling cardholder data. TeamPrompt prevents PAN from reaching AI tools, keeping them outside your CDE — preserving the scope boundary your annual assessment is built around.

What about tokenized card numbers? Do you detect those?

TeamPrompt's PAN detection uses Luhn validation, so it correctly distinguishes real card numbers from format-preserving tokens (which use distinct prefixes specifically to fail Luhn). Tokens flow through; real PANs are blocked.

How does this map to PCI-DSS v4.0 requirements specifically?

Most directly: Req 3 (protect stored cardholder data — by preventing storage in AI logs), Req 4 (encrypt transmission — by blocking transmission entirely), Req 7 (restrict access by need-to-know — via role-based AI policies), Req 10 (logging all access — via TeamPrompt's audit trail), and Req 12.3 (acceptable use policies — via documented AI tool controls).

Will your QSA accept TeamPrompt as evidence?

Several QSAs have engaged with TeamPrompt-protected environments. The evidence package documents control objectives, configuration, and effectiveness data — the format QSAs expect for any compensating control or supplementary technology. We'll provide a sample evidence package on request.

How it works

Three steps from install to full AI security coverage.

1

Install

Add the browser extension to Chrome, Edge, or Firefox — or deploy it to your whole team via MDM. No proxy or VPN needed.

2

Configure

Enable the compliance packs for your industry, set DLP rules, and add your team's prompts to the shared library.

3

Protected

Every AI interaction is scanned in real time. Sensitive data is blocked before it leaves the browser. Your team has a full audit trail.
