Retail Cyber Security Solutions: PCI DSS & Ransomware Defence
Protect your brand, customer data, and payment systems with our end-to-end cyber solutions for retail.
Expert PCI QSA services, CREST-certified pentesting, and secure network transformation to defend against ransomware.
Expert PCI DSS QSA auditing & consultancy for Retail
We are a certified PCI QSA (Qualified Security Assessor) company, working with dozens of UK retailers on their complex PCI DSS v4.0.1 requirements. We provide full auditing and consultancy, from simple SAQ A to supporting high-volume, multi-national Level 1 service providers. Our international licenses allow us to support your entire global estate, ensuring your Cardholder Data Environment (CDE) is compliant.
CREST Pentesting for PCI & e-commerce Platforms for Retail
We support your PCI DSS v4.0.1 compliance with CREST-accredited penetration testing. We offer continuous (CST) and single point-in-time pentests to fit your needs. Our testers are deeply familiar with all modern e-commerce frameworks (like Shopify, Magento, Salesforce Commerce Cloud) and payment gateways, identifying critical vulnerabilities before they can be exploited.
Secure digital transformation & ransomware defence for Retail
We know ransomware is spreading, exploiting flat, outdated networks. We implement a three-part plan: 1) Network Segmentation using Zero Trust principles to reduce your "blast radius" and contain threats. 2) 24/7 Managed Detection and Response (MDR) to identify and isolate ransomware behaviour before it spreads across your estate. 3) Strategic Cloud Migration to move key services (like EPOS or stock management) to secure AWS or Azure environments, aligned with industry standards.
24/7 Managed Detection & Response (MDR) for retail ransomware defence
Segmentation and cloud migration reduce your attack surface - but retailers also need to catch an active attack before it spreads. Our Managed Detection and Response (MDR) service monitors your estate 24/7, using threat intelligence to spot the early signs of a ransomware attack - like a device attempting to encrypt files - and isolate it before it reaches your EPOS systems, stock platforms, or customer data.
This is the same threat pattern behind the ransomware attacks that hit major UK retailers in 2025: attackers using valid credentials and social engineering to move laterally across a flat, unsegmented network. MDR, combined with the network segmentation above, is designed to contain exactly that kind of spread - protecting operational resilience across your stores, distribution centres, and e-commerce platforms.
Achieving PCI DSS compliance across 250+ stores
Heron Foods needed to overhaul how it handled cardholder data as card transactions grew across its 250+ UK stores. Working with our PCI QSA team, Heron Foods achieved full PCI DSS compliance - giving the retailer a clear, audited framework for handling payment data securely as the business continued to grow.
Protect your stores, your customers, and your compliance position
From PCI DSS v4.0.1 audits to CREST-accredited pentesting and 24/7 MDR, our retail cyber security specialists help you defend against ransomware without slowing down trading.

Cyber Faqs for Retail
-
A QSA (Qualified Security Assessor) is a company certified by the PCI Security Standards Council to perform PCI DSS v4.0.1 audits. If you are a merchant or service provider of a certain size (Level 1), you must have an annual Report on Compliance (ROC) completed by a QSA. We provide both the audit and the consultancy to help you pass.
-
Using a third-party gateway greatly reduces your scope, but it doesn't eliminate it. You still need to complete a Self-Assessment Questionnaire (SAQ), (e.g., SAQ A or SAQ A-EP), to attest that you are not handling card data directly.
-
A "flat" network allows ransomware to spread from one infected device (e.g., a staff laptop) to your critical servers (like EPOS or databases) in seconds. Network segmentation creates digital walls between these areas. If one area is breached, the attack is contained, minimizing the "blast radius" and preventing a total shutdown.
-
A PCI pentest has a specific, mandatory scope defined by the PCI DSS standard. It must test the security of your Cardholder Data Environment (CDE) and how it's segmented from the rest of your network. A standard pentest might be broader, but a PCI-specific pentest is required for compliance.
-
Yes. This is a common digital transformation project. We help retailers migrate legacy EPOS and stock management systems to modern, cloud-native solutions on AWS or Azure. This improves resilience, scalability, and, when built correctly, enhances your security and simplifies PCI compliance.
