WHY AI IS THE NEW PCI RISK

AI Is Now the Fastest Way Card Data and Secrets Leave Your Stack

Your payments stack is locked down, tokenized and audited. AI prompts aren't. Engineers paste live logs and configs into a browser tab, often from personal accounts, and legacy DLP never sees it.

#1

GenAI is now the top channel for corporate data moving to personal accounts, carrying 32% of it.

77%

of employees using GenAI paste data straight into prompts.

82%

of those pastes happen in unmanaged personal accounts your tools can’t see.

What just happened

  • Cardholder data sent outside your PCI DSS scope and controls
  • A live API key exposed to a third party, now a rotation incident
  • No record for your QSA or SOC 2 auditor of where the data went
One prompt, sent in under a second. Instant PCI and SOC 2 exposure.

Never stored

PCI DSS prohibits storing sensitive authentication data such as the CVV after authorization. A CVV pasted into an AI prompt is now stored by a third party you have never assessed.

Why Employee AI Use Puts Fintech Compliance at Risk
‍

01

Engineers Debug With Production Data

Logs, payloads and stack traces carry card numbers, account data and live keys straight into AI assistants.

02

Secrets Leak in a Single Paste

One pasted config file can hand an AI vendor a live API key and turn a debugging session into an incident.

03

Bank Partners Ask Hard Questions

Sponsor banks, card networks and enterprise customers expect proof that AI use is controlled, not just a policy PDF.

04

Support Handles KYC Every Day

ID documents, bank statements and dispute details get pasted into AI to draft replies faster.

The Fintech Data Wald Protects

Fintech prompts mix customer, payments and engineering data. These are the types that surface most often in AI prompts at payments, lending and banking-as-a-service companies. Wald detects each one on the device, by context, and you choose Allow, Warn or Block.

Cardholder data

PCI-scoped data that turns up in logs.

  • Card numbers (PAN)
  • CVV
  • Expiry dates
  • Cardholder names
  • Track data

Bank & account data

Money movement details in ops and support.

  • Account numbers
  • Routing numbers
  • IBANs
  • Balances
  • Transactions

KYC & identity

Onboarding documents pasted for review.

  • SSNs
  • Passports
  • Driver’s licenses
  • Selfie checks
  • Proof of address

Credentials & secrets

One paste away from an incident.

  • API keys
  • Access tokens
  • Private keys
  • Database URLs
  • Webhook secrets

Source code & infra

The engineering that makes you different.

  • Proprietary code
  • Fraud rules
  • Infra configs
  • Architecture docs
  • Production logs

Lending & risk

Models and decisions regulators scrutinize.

  • Credit scores
  • Underwriting models
  • Fraud scores
  • Income data
  • Collections notes

Disputes & support

Customer cases pasted for faster replies.

  • Chargeback files
  • Dispute evidence
  • Support tickets
  • Chat transcripts
  • Complaints

Business confidential

Partner and strategy information.

  • Bank partner terms
  • Pricing
  • Investor updates
  • Board decks
  • Roadmaps

PCI DSS, SOC 2 and GLBA all expect you to control where sensitive data goes. Today, that includes AI prompts.

Stop card data and secrets before they reach AI

Wald’s on-device models recognise card numbers, account data and live credentials by context, so a production log or config file never leaves the laptop inside a prompt.

  • Card, account & KYC detection
  • API keys, tokens & secrets
  • Context, not just pattern matching

Apply fintech policies with Allow, Warn, or Block

Set rules per data type, team and AI tool. Block card data and secrets outright, warn on customer names, and allow everyday coding help, so engineers keep shipping.

  • Per-data-type, per-team policies
  • Inline coaching before a block
  • Free and paid AI tools covered

Evidence for your QSA, auditors and bank partners

Every AI interaction is logged with user, tool, data type and policy outcome, so you can show PCI and SOC 2 auditors how AI is controlled, answer bank partner diligence and investigate incidents fast.

  • Centralised audit trail
  • Exportable reports for auditors & partners
  • Per-user, per-tool records

An Enterprise AI Plan Alone vs. Wald for Fintech

Enterprise AI plan alone
With Wald
Card data and keys still leave the laptop
Card data and secrets stopped on the device
Live API keys pass unchecked
Secrets blocked before a rotation incident
No evidence for your QSA or bank partners
Exportable record for PCI and SOC 2 audits
Covers only the one tool you license
Covers the AI assistants engineers actually use

Wald enables our employees to safely leverage leading AI models so they can reduce the time they spend on manual tasks. Our traditional DLP was built for email and file transfers and not AI prompts. Wald gave us real visibility and control over how our employees use LLMs without slowing productivity.

Frequently Asked Questions

Talk to Sales

Can engineers use AI assistants without breaking PCI DSS?

Yes, as long as cardholder data stays out of the prompt. Pasting a production log with card numbers into an AI tool puts that data outside your PCI DSS scope and controls.

‍

Wald stops card data and secrets on the device, so engineers keep using AI for everyday coding.

Does Wald detect API keys and other secrets?

Yes. Wald recognises live API keys, access tokens, private keys, database connection strings and passwords in prompts and pasted files.

‍

You can block them outright, so a debugging session never turns into a key rotation incident.

Is an enterprise AI plan enough for a fintech?

Enterprise plans typically stop the vendor from training on your data, but card and customer data still leaves the device and is stored by a third party. They also cover only the tool you license, not the free tools engineers use on the side. Wald adds on-device detection and control across the AI tools your teams actually use.

Which fintech data does Wald detect?

Card numbers and CVVs, bank account and routing numbers, KYC documents, SSNs, credit and fraud data, and credentials and secrets.

‍

On-device models understand context, not just patterns, and you decide whether each type is allowed, warned on or blocked.

Which frameworks does Wald help fintechs meet?

Wald helps you maintain PCI DSS, SOC 2, GLBA and bank partner requirements wherever AI is involved, plus GDPR for customers outside the US.

‍

It does this by keeping regulated data out of AI tools and giving you an exportable record of every AI interaction.

How quickly can we roll out Wald across engineering and support?

Wald runs as a lightweight agent across browser and desktop, deployed through your existing MDM, so you can start seeing AI usage across engineering, support and operations soon after rollout. We'll map out a deployment plan with you during your demo.
