The Payment Card Industry Data Security Standard, a set of security requirements for organisations handling cardholder data.
PCI DSS Compliance & Payment Security
Structured guidance to scope cardholder data environments, assess PCI DSS requirements and prepare for validation through a SAQ, QSA or ASV. Trust Statement Supporting merchants, payment processors and technology platforms in aligning with PCI DSS requirements.
- Cardholder Data Environment (CDE) scoping.
- Gap assessment against the 12 PCI DSS requirements.
- Segmentation and network architecture review.
Introduction
Understanding Your PCI DSS Scope
Any organisation that stores, processes or transmits cardholder data — whether a retail business, e-commerce platform, payment gateway or SaaS billing product — falls within the scope of PCI DSS.
Non-compliance can have consequences including increased transaction fees, potential loss of card processing privileges and significant liability in the event of a card data breach.
PRSECURITY CONSULTANCY & SERVICES begins every PCI DSS engagement with careful Cardholder Data Environment (CDE) scoping — identifying exactly where card data is stored, processed or transmitted and how network segmentation can reduce the systems that fall within audit scope.
PCI DSS Sub-Services
Our PCI DSS Compliance Services
1. Cardholder Data Environment (CDE) Scoping
Description
Identification of all systems, applications and network segments that store, process or transmit cardholder data.
Workflow
Data flow mapping → network architecture review → scope boundary definition → segmentation recommendations
Deliverables
CDE scope document and data flow diagrams.
2. Gap Assessment Against PCI DSS Requirements
Description
Review of current controls against all 12 PCI DSS requirement categories.
Workflow
Control walkthroughs → evidence review → gap identification → remediation roadmap
Deliverables
Gap assessment report and remediation roadmap.
3. Network Segmentation Review
Description
Assessment of network architecture to validate effective isolation of the CDE from other systems.
Workflow
Architecture review → segmentation testing coordination → recommendations
Deliverables
Segmentation review report.
4. SAQ Preparation Support
Description
Guidance completing the appropriate Self-Assessment Questionnaire based on merchant/service provider level.
Workflow
SAQ type determination → control walkthrough → response drafting support → evidence organisation
Deliverables
Completed SAQ draft and supporting evidence index.
What Does PCI DSS Compliance Cover?
PCI DSS readiness starts with understanding where cardholder data flows and which systems fall within the compliance boundary.
CDE Scoping
Identify systems, applications and network segments that store, process or transmit cardholder data.
PCI DSS Requirements
Assess controls against the 12 PCI DSS requirement categories.
Network Segmentation
Review isolation of the Cardholder Data Environment from other systems.
SAQ Preparation
Prepare the appropriate Self-Assessment Questionnaire based on the organisation's payment environment.
QSA Assessment
Prepare for formal assessment by a Qualified Security Assessor where required.
ASV Validation
Coordinate with an Approved Scanning Vendor where formal validation is required.
Why Should You Conduct a PCI DSS Assessment?
Understand your PCI DSS compliance boundary, identify control and process gaps, strengthen the safeguards supporting secure payment operations, and reduce unnecessary scope before moving into formal validation.
- Reduce audit scope and associated compliance costs
- Understand where cardholder data actually flows
- Identify weaknesses before QSA or ASV assessment
- Validate network segmentation
- Prepare accurate SAQ submissions
- Improve QSA / ASV assessment readiness
- Support continued payment processing
- Reduce card data exposure and associated liability
Our PCI DSS Working Methodology
A structured approach covering CDE scoping, assessment, segmentation, validation preparation and remediation.
CDE Scoping
Identify and document the systems, applications, network segments, and environments involved in cardholder data flows to establish a clear and accurate PCI DSS compliance boundary.
01Data Flow Mapping
Map how cardholder data is stored, processed, and transmitted across the relevant environment to understand data movement and support a structured PCI DSS assessment.
02Gap Assessment
Assess existing controls and processes against applicable PCI DSS requirements, identify gaps, and establish a clear understanding of areas requiring attention before formal validation.
03Segmentation Review
Review network architecture and segmentation controls to clarify the compliance boundary, understand connected environments, and support an appropriately defined PCI DSS scope.

BENEFITS OF PCI DSS COMPLIANCE
Key Benefits of PCI DSS Readiness
Reduced Audit Scope
Reduce unnecessary audit scope by establishing a clear PCI DSS compliance boundary and focusing assessment efforts on the systems, applications, and environments that are actually relevant.
Clearer Data Visibility
Gain a clearer understanding of where cardholder data is stored, processed, and transmitted across the environment, supporting better visibility into the overall payment data flow.
Lower Data Risk
Strengthen controls around cardholder data to reduce potential exposure, lower the risk of payment card breaches, and address associated security and compliance concerns.
Assessment Readiness
Prepare for QSA or ASV assessments with a clearer compliance boundary, documented data flows, and an understanding of the controls and requirements that need to be addressed.
Stronger Payment Relationships
Support stronger relationships with payment processors and acquirers by maintaining a structured approach to PCI DSS requirements and secure payment operations.
Reduced Transaction Risk
Reduce the risk of compliance-related issues that may contribute to increased transaction fees, while supporting secure and compliant payment processing operations.

Your Questions, Answered!
-
1 What is PCI DSS?
-
2 Who needs to comply with PCI DSS?
Any merchant, processor or service provider that stores, processes or transmits cardholder data.
-
3 What is the Cardholder Data Environment (CDE)?
The systems, people and processes that store, process or transmit cardholder data, plus connected systems.
-
4 What is a SAQ?
A Self-Assessment Questionnaire used by eligible merchants to validate PCI DSS compliance.
-
5 When is a QSA assessment required instead of a SAQ?
Typically for higher transaction volumes or as required by acquirers or card brands.
-
6 Can outsourcing payments reduce PCI scope?
Yes, using a compliant third-party payment processor can significantly reduce an organisation's own scope.
