Book a Free PCI DSS Gap Assessment View Our PCI DSS ServicesIreland has become one of Europe's busiest payment processing hubs. Dublin alone hosts the European operations of Stripe, PayPal, and hundreds of other IFSC-based financial services firms, while Cork, Galway, and Limerick are home to a fast-growing base of e-commerce, fintech, and SaaS companies that all touch cardholder data in some form.
The Payment Card Industry Data Security Standard (PCI DSS) isn't optional guidance — it's a contractual requirement enforced by Visa, Mastercard, and every other card scheme the moment your business stores, processes, or transmits cardholder data. Irish payment and e-money institutions already sit under close supervision from the Central Bank of Ireland, and with DORA now in force for financial entities and NIS2 on the way, the overall compliance bar for Irish businesses is rising fast. PCI compliance is usually the first checkpoint auditors and acquiring banks look for.
Whether you're a Level 1 merchant processing millions of transactions a year out of Dublin, or a growing online retailer in Cork or Galway handling your first few thousand card payments, VISTA InfoSec brings the same rigor: a clear scoping exercise, a realistic remediation plan, and a Report on Compliance your acquiring bank will actually accept.
From first-time PCI DSS certification to ongoing PCI compliance maintenance, our QSA-led team covers every PCI DSS requirement — on-site across Ireland or fully remote.
We map exactly where cardholder data lives across your Dublin, Cork, or hybrid-cloud environment, and narrow your PCI DSS requirements footprint before remediation begins.
Full QSA-led assessment and Report on Compliance (ROC) for organizations processing over 6 million card transactions a year.
For Level 2–4 merchants, we identify the correct PCI SAQ (Self-Assessment Questionnaire) type and guide you through every applicable control.
We build the PCI DSS policy set auditors expect — information security policy, incident response plan, access control policy, and vendor management procedures.
An independent, vendor-neutral PCI DSS audit against the current PCI DSS standard, conducted by our Qualified Security Assessors.
Quarterly Approved Scanning Vendor (ASV) scans and annual segmentation penetration testing, required under PCI DSS Requirement 11.

Year-round support to keep your PCI DSS certification current as your systems, vendors, and card volumes change.

Define your cardholder data environment and benchmark it against PCI DSS requirements.
Close identified gaps with practical, prioritized fixes — not a 200-page report you're left to interpret alone.
Draft and finalize the PCI DSS policy set your QSA and acquiring bank will expect to see.
Formal assessment, ASV scanning, and segmentation testing against the current PCI DSS standard.

Our PCI DSS consultants work on-site or remotely with organizations nationwide, including:
Home to the IFSC and the European operations of Stripe, PayPal, and hundreds of other payment and fintech firms — Ireland's highest concentration of PCI DSS scope.
A growing hub for tech, pharma, and e-commerce exporters that process card payments across the EU and beyond.
Medtech and software companies expanding into payment features and subscription billing that fall under PCI DSS scope.
Retail, logistics, and manufacturing businesses adding online and in-store card payment channels.
SMEs and regional retailers working toward their first PCI DSS SAQ or full certification.
Wherever you're based in Ireland, our assessments combine remote evidence review with on-site visits where required.
We're a vendor- and product-neutral PCI DSS consultancy — we don't sell firewalls, scanning tools, or hosting, so our gap analysis and audit findings are never shaped by what we have to sell you afterward.
With offices across the US, UK, UAE, India, and Singapore, we bring the same QSA rigor used with global enterprise clients to Irish merchants and payment providers of every size.
Most of our Irish PCI DSS clients are also working through one or more of these — worth reviewing alongside your PCI DSS certification roadmap.
PCI DSS compliance means your business meets the Payment Card Industry Data Security Standard's 12 core requirements for handling cardholder data — covering areas like network security, access control, encryption, monitoring, and policy. It applies to any organization that stores, processes, or transmits card data, regardless of size.
PCI DSS stands for Payment Card Industry Data Security Standard — a set of security requirements created by the major card brands (Visa, Mastercard, American Express, Discover, JCB) and maintained by the PCI Security Standards Council.
PCI DSS Level 1 applies to merchants processing more than 6 million card transactions annually, or any merchant that has experienced a data breach involving cardholder data. Level 1 merchants require a full QSA-led audit and Report on Compliance, rather than a self-assessment questionnaire.
The path to PCI DSS certification runs through scoping your cardholder data environment, closing any gaps against the PCI DSS requirements, completing the correct SAQ or a full QSA audit depending on your merchant level, and receiving a signed Attestation of Compliance (AOC). VISTA InfoSec manages this end-to-end for businesses across Ireland.
Beyond the card brands' contractual requirement, non-compliance can mean fines from your acquiring bank, increased transaction fees, and in the event of a breach, liability for fraud losses. With Ireland's growing concentration of payment and fintech companies, acquiring banks and partners increasingly expect PCI DSS certification as a baseline before they'll even sign a contract.
A PCI SAQ (Self-Assessment Questionnaire) is a validation tool for merchants that don't require a full QSA audit. There are several SAQ types (A, A-EP, B, C, D, and others) depending on how you accept and process card payments. We identify the correct type for your business as the first step of any engagement.
Cost depends on your merchant level, the size of your cardholder data environment, and how much remediation is needed before assessment. A Level 4 merchant completing a straightforward SAQ will spend far less than a Level 1 merchant requiring a full QSA audit. We provide a fixed-scope quote after an initial gap analysis, so there are no surprises.
