PCI DSS Compliance & Certification in the United States

PCI DSS is the global cybersecurity standard for any organisation that stores, processes or transmits cardholder data. The US is the largest card payments market in the world, with the most aggressive threat targeting of cardholder data and the most actively enforced card brand compliance programmes.

RedSecLabs delivers PCI DSS v4.0.1 compliance services to organisations in the United States and across global markets. QSA-aligned scoping, gap remediation, formal Report on Compliance (ROC) for Level 1 and qualifying service providers, Self-Assessment Questionnaire (SAQ) support for lower levels, and the segmentation and e-commerce skimming controls v4.0.1 now demands.

Our assessors combine deep PCI DSS methodology with payments-sector experience. We deliver PCI DSS for US-headquartered organisations, US subsidiaries of international groups, and global payment businesses with US merchant operations. In the US, PCI DSS interacts with state-level data breach notification laws, the New York DFS 23 NYCRR 500 cybersecurity regulation for financial services, and sectoral regulators including the FTC for unfair-deceptive practices following payment data incidents. Our methodology aligns to QSA practice and produces ROC and SAQ artefacts that US acquirers, card brands and forensic investigators recognise.

Why a the United States PCI DSS partner matters

PCI DSS is set globally by the PCI Security Standards Council, but how it lands operationally in the United States depends on acquirer relationships, card brand expectations, local regulator stance on cyber, and the operating reality of payment processing in the United States. A global standard delivered by a generic global vendor can miss what your acquirer and local regulator actually expect from the evidence pack.

Our delivery model is shaped by working with the United States-based payment businesses and the acquirers they report to. That includes coordinating with your acquirer and merchant bank on attestation submissions, dealing with local interpretations of v4.0.1 e-skimming requirements, and aligning PCI DSS with other regulatory regimes that apply to your operations.

What our PCI DSS engagements deliver:

Accurate scope reduction that materially lowers ongoing cost

QSA-aligned formal Report on Compliance (ROC) where required

SAQ support for Level 2-4 merchants

PCI DSS v4.0.1 new requirements covered (e-skimming, software supply chain)

Acquirer-shareable Attestation of Compliance (AOC)

Segmentation testing where scope reduction depends on it

From single-channel e-commerce merchants in the United States through to multi-country payment service providers, our delivery model scales while staying QSA-aligned throughout.

Why PCI DSS in the United States is non-negotiable

For any organisation in the United States that touches cardholder data, PCI DSS compliance is a contractual requirement, not optional. Card brand (Visa, Mastercard, Amex, JCB, Discover) compliance programmes flow through your acquirer to you, and the consequences of non-compliance escalate quickly.

The threat landscape in the United States has been hostile to payment businesses for several years. Magecart-style web-skimming attacks against e-commerce checkouts are now industrialised. Ransomware against retail and hospitality has caused multi-week trading outages. Payment fraud is automated and the data feeding it is increasingly sourced through compromised cardholder data environments.

Without strong PCI DSS posture, organisations in your market face:

Acquirer-imposed fines under card brand compliance programmes

Termination of merchant or acquirer relationship

Card brand investigation and forensic mandate after any incident

Increased interchange and processing fees

Reputational damage in the card brand monitoring programmes

Customer trust loss and contractual breach exposure with B2B clients

PCI DSS is rarely the most exciting compliance work. Done well by the right partner, it is one of the least disruptive things on your security roadmap.

Who in the United States needs PCI DSS

Anyone in the United States who stores, processes or transmits cardholder data falls under PCI DSS. In practice, that covers:

Payment Service Providers

E-commerce Merchants

Banks & Issuers

Retail & Hospitality

Restaurants & QSR

Payment Tech & ISVs

Logistics & Fulfilment

Marketplaces

Whether you are a Level 1 merchant requiring annual ROC, a Level 2-4 merchant on SAQ, or a service provider in scope of PCI DSS in your own right, our methodology adapts to your level without compromising on QSA-grade rigour.

How we deliver PCI DSS in the United States

Eight-stage delivery process, adapted to your merchant level, acquirer relationships and payment channels. Fixed-fee scope, single point of contact, evidence reuse against ISO 27001 and SOC 2 where applicable.

01

Scoping & Cardholder Data Discovery

We map every system that stores, processes, or transmits cardholder data, plus systems with logical connectivity to those, to define the scope precisely. Most engagements reduce scope materially at this stage.

02

Gap Assessment Against PCI DSS v4.0.1

Detailed review of every applicable PCI DSS requirement, control by control, with evidence sampling. Output is a remediation roadmap before any formal attestation begins.

03

Remediation Support

Hands-on support on the requirements where most organisations fall short: encryption, MFA, logging, vulnerability management, segmentation, and the new v4.0.1 controls around e-skimming and software supply chain.

04

Segmentation Testing

Independent segmentation testing where in scope, proving the boundaries you rely on for scope reduction actually hold.

05

Formal Assessment (ROC / SAQ)

QSA-aligned formal assessment producing the Report on Compliance (ROC) for Level 1 merchants and service providers, or Self-Assessment Questionnaire (SAQ) support for lower levels.

06

AOC and Submission Support

Attestation of Compliance preparation and acquirer/customer submission support. We handle the formal artefacts so your team focuses on the business.

07

Annual Refresh

Annual reassessment with retained evidence base, so subsequent years are materially cheaper than year one. Quarterly review meetings keep posture fresh between assessments.

08

Incident Response Standby

Pre-arranged incident response for in-scope environments, with acquirer notification handling under card brand rules and forensic capability when required.

Most clients complete first-year ROC in 12 to 16 weeks. SAQ engagements compress to 4 to 8 weeks. Annual refresh is materially cheaper than year one once the evidence base is mature.

Frequently Asked Questions

Yes. We deliver PCI DSS to merchants, payment service providers and acquirers based in the United States, regardless of where their data is processed or stored. Engagements are scoped to your operational reality, your acquirer expectations, and the local regulatory context.

PCI DSS v4.0.1, the current version. Where you are mid-cycle and need bridging work to move from v3.2.1 to v4.0.1, we cover that as part of the engagement.

Yes. Level 1 merchants and qualifying service providers requiring annual ROC are a core engagement type. Our methodology is QSA-aligned throughout, with the formal report quality acquirers and card brands expect.

Almost always, yes. Most organisations carry PCI DSS scope that has crept over time. We start with scoping and cardholder data discovery, and a well-executed scoping exercise typically reduces ongoing PCI DSS effort by 30-60% versus the previous year. The scoping work alone often pays for itself.

Yes. Submission of the AOC to your acquirer, response to follow-up questions, and any further evidence requests from the acquirer or card brands are handled by us alongside the technical assessment.

Engagements are scoped to your merchant level, payment channels in scope, and the technology stack handling cardholder data. We confirm fixed-fee scope within 48 hours of a scoping call. Annual refresh is materially cheaper than year one once we have your evidence base.
