PCI DSS Programme

Overview

PCI DSS compliance is often treated as an annual scramble to complete a questionnaire or satisfy an assessor, when it should be a continuous property of how your systems are architected and operated. Pay Engineers runs PCI DSS programmes that start by asking the most valuable question first: can we reduce the scope of cardholder data environment before we spend effort hardening it?

Scope reduction, primarily through tokenisation, network segmentation and careful architecture choices, is consistently the highest-leverage activity in a PCI programme, because every system removed from scope is a system your team no longer needs to maintain evidence for, indefinitely, every year. We prioritise this before diving into granular control implementation.

We work directly alongside your Qualified Security Assessor rather than in place of one, since QSA validation is a mandatory part of most compliance levels. Our role is to make sure the architecture and evidence your assessor reviews is genuinely solid, not just superficially compliant.

Who This Is For

• Merchants and payment businesses approaching their first PCI DSS assessment
• Organisations whose cardholder data environment has grown organically and needs formal scoping
• Businesses that have failed or struggled through a previous assessment and need a structured remediation programme
• Companies wanting to reduce PCI scope and ongoing compliance overhead through architecture changes rather than accepting the status quo

What You Get

• A scope workshop that maps every system, process and data flow touching cardholder data, producing a clear scope boundary
• Control mapping translating PCI DSS requirements into specific, actionable technical and procedural controls for your environment
• Evidence pack templates that make annual assessment preparation dramatically faster in subsequent years
• A prioritised remediation backlog so your team knows exactly what to fix first for the greatest scope and risk reduction

Technical Approach

Network segmentation is assessed and redesigned where necessary to isolate the cardholder data environment from the rest of your infrastructure, since poor segmentation is one of the most common reasons PCI scope balloons beyond what is actually necessary. Where card data is currently stored or transmitted in more places than needed, we introduce a token vault so that raw card data is replaced with tokens throughout the majority of your systems, removing them from scope entirely.

Logging and SIEM capability is reviewed against PCI DSS logging and monitoring requirements, since evidence of continuous monitoring is a recurring weak point in assessments we see. Controls are implemented with the explicit goal of being sustainable year over year, not a one-time push to pass a single assessment, because the real cost of PCI compliance is the ongoing operational burden, not the initial project.

Delivery Process

• Scope workshop with stakeholders across engineering, operations and finance to map the true cardholder data environment
• Control mapping against the specific PCI DSS requirements applicable to your merchant or service provider level
• Remediation work addressing the highest-priority gaps, run in coordination with your QSA where validation is needed along the way
• Evidence pack preparation and internal walkthrough ahead of formal assessment
• Support through the assessment itself and definition of a sustainable annual compliance cadence afterward

Outcomes and Benefits

• A materially smaller cardholder data environment, reducing both risk and ongoing compliance cost
• A clear, prioritised remediation backlog instead of an overwhelming and undifferentiated list of findings
• Evidence templates and processes that make future assessments faster and less disruptive to your teams
• Stronger security posture as a byproduct of compliance work, not just a checkbox exercise
