PCI DSS - Payment Card Industry Data Security Standard
Before any organization can protect payment card information, it has to know where that information sits. EzSecure scans the storage platforms your teams already use, finds cardholder data hiding in spreadsheets, exports and shared folders, and classifies it so your PCI DSS initiatives start from an accurate picture instead of a guess.
THE STANDARD
What PCI DSS Actually Requires
PCI DSS, short for Payment Card Industry Data Security Standard, is a set of technical and operational requirements maintained by the PCI Security Standards Council. It applies to any organization that stores, processes or transmits payment card information, regardless of size or industry.
The standard exists because payment card data has real value to criminals and real consequences for the people whose cards get exposed. A single unprotected export or an old spreadsheet full of card numbers can turn into a breach notification, a regulatory conversation and a lot of lost trust.
Merchants, payment processors, SaaS companies that handle billing, and any service provider that touches cardholder data on behalf of a client should all be thinking about PCI DSS. Even businesses that outsource payment processing usually still hold some cardholder data in support tickets, refund records or finance files.
None of the requirements matter much if nobody can say where the data actually is. Visibility comes first. Everything else in a PCI DSS program, from access control to encryption to monitoring, depends on an accurate inventory of where cardholder data lives across the business.
Who it applies to
Merchants, processors, and any provider storing or transmitting cardholder data
Why visibility comes first
Controls cannot protect data that security teams do not know exists
THE PROBLEM
The Hidden Risk of Payment Card Information
Cardholder data rarely stays inside the systems that were built to protect it. A support agent pastes a card number into a ticket while troubleshooting a failed charge. A finance analyst exports a batch of transactions into a spreadsheet for a reconciliation report. An old invoice gets emailed with an account number that was never fully masked.
Over time, these small moments add up. Payment information spreads into customer records, invoices, financial reports, email attachments, shared folders, cloud storage, archived files and legacy systems that almost nobody logs into anymore. Each of these copies sits outside the boundary that the official cardholder data environment was designed around.
Organizations lose track of this data for ordinary reasons. People change roles, folders get shared and forgotten, migrations move files without anyone reviewing the contents first. By the time an audit or an incident forces the question, security teams are often finding out about these copies for the first time.

What It Covers
How EzSecure Supports It
Build and Maintain Secure Systems
Configuration standards for the networks and systems that touch cardholder data.
Helps confirm where cardholder data actually resides so those systems can be scoped with confidence.
Protect Cardholder Data
Rules for storing account data and rendering it unreadable wherever it sits.
Surfaces stored account numbers that fall outside approved storage locations, so they can be reviewed.
Protect Stored Account Data
Retention limits and rules against keeping sensitive authentication data after authorization.
Flags old exports and archived files still holding account data that may be past its retention window.
Encrypt Transmission of Cardholder Data
Protecting card data as it moves across open or public networks.
Classification highlights files containing card data that could be shared or transmitted without adequate protection.
Restrict Access to Cardholder Data
Need to know access controls for anyone who can view payment information.
Shows which shared drives and folders contain cardholder data, so access can be reviewed and tightened.
Identify and Authenticate Users
Unique IDs and authentication for anyone with access to cardholder data systems.
Discovery findings help define which systems and accounts genuinely need these controls applied.
Monitor and Log Access
Tracking and logging activity around cardholder data.
Gives monitoring and logging efforts a clear map of where cardholder data actually sits.
Regular Security Testing
Periodic testing of systems, networks and processes.
Provides testing and scoping teams a current, evidence based starting point instead of outdated assumptions.
BUSINESS USE CASES
Where Cardholder Data Discovery Fits In
Preparing for a PCI DSS Assessment
Challenge
Assessors ask where cardholder data lives, and the honest answer is often that nobody is fully sure.
Why it matters
An assessment moves faster and costs less time when scope is based on evidence rather than memory.
How EzSecure helps
Discovery results give compliance teams an inventory of cardholder data locations to walk in with.
Reducing Manual Searches
Challenge
Security and compliance staff spend hours opening folders one by one looking for card data.
Why it matters
Manual review does not scale, and it misses far more than it ever finds.
How EzSecure helps
Automates the scanning work, freeing teams to review findings instead of hunting for them.
Finding Cardholder Data Before Cloud Migration
Challenge
Moving file shares to the cloud risks carrying old cardholder data along without anyone noticing.
Why it matters
Catching payment data before a migration is far simpler than cleaning it up afterward.
How EzSecure helps
Scans source repositories ahead of time and flags files that need review before they get copied forward.
Supporting Payment Data Governance
Challenge
Without a clear owner or policy, cardholder data quietly accumulates with no plan for handling it.
Why it matters
Governance decisions need a starting inventory to actually work from.
How EzSecure helps
Classification results give governance programs a foundation for building retention and handling policy.
Locating Payment Data Across Shared Repositories
Challenge
Card numbers often end up in shared drives that were never meant to hold them.
Why it matters
Shared folders are usually the least controlled part of any environment.
How EzSecure helps
Scans Google Drive, OneDrive, SharePoint and Windows File Server to locate cardholder data wherever it landed.
Reviewing Archived Financial Records
Challenge
Years of old financial exports and reports pile up in archives that nobody checks anymore.
Why it matters
Archived files often hold cardholder data long after it should have been removed.
How EzSecure helps
Scheduled scans reach into archived storage and surface what is quietly sitting there.
