Definition

What is PCI DSS compliance consulting?

PCI DSS compliance consulting takes an organization from an unclear cardholder data environment to a validated assessment. The Payment Card Industry Data Security Standard is a contractual requirement, enforced by the card brands through your acquiring bank, and it applies to any organization that stores, processes, or transmits cardholder data. The current version is v4.0.1, and the future-dated requirements introduced in v4.0 became mandatory on March 31, 2025, so every control in the standard is now in force. BD Emerson is not a QSA company and does not sign Reports on Compliance. We work on your side of the assessment: shrinking scope, assessing gaps across the 12 requirements, fixing what fails, and preparing the SAQ or the ROC evidence your QSA will test. That separation is deliberate, because the firm preparing you should have no stake in passing you.

PCI scoping and scope reduction

Cost scales with scope, so engagements start by mapping every system that stores, processes, or transmits cardholder data, plus everything connected to it. Then we shrink the footprint: network segmentation that isolates the cardholder data environment, tokenization that removes stored PANs, hosted payment pages that keep card data off your servers, and P2PE terminals that encrypt at the point of interaction. Every system removed from scope is one nobody has to remediate, document, or assess again.

PCI DSS gap assessment against v4.0.1

A control-by-control review of your environment against all 12 PCI DSS requirement families, from network security controls under Requirement 1 to the targeted risk analyses v4.0.1 expects. Each finding carries the requirement number, the evidence an assessor will request, the fix, and an owner. Requirements that were future-dated under v4.0, including multi-factor authentication for all access into the CDE and authenticated internal scanning, became mandatory on March 31, 2025 and are assessed accordingly.

Remediation and control implementation

We close findings instead of handing you a list: cardholder data discovery and storage cleanup under Requirements 3 and 4, access control and MFA rollout under Requirements 7 and 8, logging and monitoring under Requirement 10, and the segmentation changes that shrink scope. Work is sequenced so long-lead items such as network changes and legacy PAN elimination start first, and each fix ends with the artifact that proves the control operates.

SAQ preparation for merchants and service providers

Merchants below Level 1 usually validate through a Self-Assessment Questionnaire, and picking the wrong SAQ is the most common error we correct. Which SAQ applies depends on how payments flow: SAQ A when card handling is fully outsourced to validated third parties, SAQ A-EP when your website affects how card data is redirected, and SAQ D when the flows exceed the narrower types or you are a service provider. We confirm eligibility, then complete the questionnaire with evidence behind every answer.

ROC preparation support alongside your QSA

Level 1 merchants and many service providers validate through a Report on Compliance signed by a QSA or a qualified ISA. BD Emerson does not sign ROCs. We prepare you for the assessor who does: evidence indexed by requirement, interviews rehearsed, compensating control and customized approach documentation drafted where a control cannot be met as written, and findings closed before fieldwork. Assessments run shorter when the QSA never has to chase an artifact.

Penetration testing, ASV scans, and ongoing evidence

Requirement 11.4 requires internal and external penetration testing at least annually and after significant changes, and BD Emerson performs that testing itself, including segmentation validation. Quarterly external vulnerability scans under Requirement 11.3.2 must come from a PCI-approved scanning vendor, so we coordinate the ASV, triage results, and drive rescans to passing. Between assessments we run the evidence calendar v4.0.1 sets: quarterly scans, annual security awareness training, and the recurring targeted risk analyses.

Our approach

Our approach to PCI DSS compliance

The sequence is the same whether you file an SAQ or face a QSA, and it is grounded in our work with retail and e-commerce companies.
01

Scope before anything else

We map cardholder data flows first, then cut scope with segmentation, tokenization, or a hosted payment page before assessing a single control. Descoping is the highest-return move in PCI because every cost that follows is proportional to scope.

02

Assess against the current standard

The gap assessment runs against PCI DSS v4.0.1 with nothing deferred, since the last future-dated requirements came into force on March 31, 2025. You get a remediation plan with requirement numbers, owners, and dates.

03

Remediate with evidence as you go

Findings close in priority order, and each control produces its artifact when the work finishes, so evidence accumulates during remediation instead of being reconstructed in the assessment window.

04

Validate, then keep the calendar

We complete the SAQ with you or support the QSA's ROC fieldwork, then keep quarterly scans, annual training, and periodic reviews on schedule, so next year's assessment starts from current evidence.

Our Advantage

Why BD Emerson for PCI DSS

Independent of the assessment

BD Emerson is not a QSA company, so our advice is judged only on whether you validate. We prepare you, and an independent assessor examines you, which is the separation acquirers and enterprise customers expect to see.

Testing performed in house

The penetration testing Requirement 11.4 demands, internal, external, and segmentation validation, is performed by our own offensive security team and retested after fixes, while ASV scans run through PCI-approved vendors we coordinate.

Scope reduction pays for the work

Descoping is treated as the first deliverable because cost scales with scope. Segmentation, tokenization, and hosted payment pages routinely remove whole system groups from the CDE, and the savings recur every assessment year.

How We Work

How we deliver PCI DSS compliance

One sequence runs every engagement, from a first SAQ A filing to a Level 1 service provider ROC. Each step produces evidence your assessor can test.

We had a hard time finding the right company to partner with in support of our compliance journey. Some vendors sell the idea that they do the work, but then you end up doing everything. The ambiguity is what killed our last project. BD Emerson’s team has such great technical knowledge and understands the standard so well that they made us comfortable with moving fast. This has led to us closing major enterprise customers that were previously out of reach because of security and compliance.

CEO @ AMI AssetTrack

Lead an enterprise initiative to overhaul the organization's technology stack from ecommerce, corporate tech, and corporate security.

Supported ISO 42001 exercise and served as internal auditor.

Rubrik's privacy and compliance team began with the backbone of BD Emerson. BD Emerson supported building out the privacy program, GRC (ISO 27001, SOC 2, CMMC, FedRAMP), and the appsec function.

We needed a partner who could move quickly, without sacrificing precision. BD Emerson brought the expertise, structure, and speed we were looking for. Their team became an extension of ours, embedding themselves across the organization, guiding us step by step, and giving us confidence in areas we hadn’t tackled before. The internal audit they conducted was so detailed that even the external auditors called it out. Achieving ISO 27001 with zero nonconformities says everything you need to know about the quality of the partnership.
