Retail
Protect tills, checkouts and customer data without slowing the sale. Falx helps UK retailers scope PCI DSS, secure stores and e-commerce, and stay trading on their busiest days.
Service Details
Cyber security for retailers means protecting every place you take money or hold customer data, without slowing the sale. Tills, payment terminals, e-commerce checkouts and loyalty apps all give attackers a way in. You get a team that secures them together, so your acquirer gets evidence and your customers get a checkout they can trust.
We work with UK retailers across stores, online and head office. Our engineers test and harden your systems, and our compliance specialists map that work to the Payment Card Industry Data Security Standard (PCI DSS), UK GDPR and Cyber Essentials. See how we support other sectors on our industries page.
INFO
Every till, website and loyalty app you run takes money or data, often both. You get scoped PCI DSS compliance, hardened checkouts and customer data protection that holds up on your busiest day.
Where retailers get hit
You defend three fronts at once, and attackers pick the weakest:
Payments everywhere
Tills, terminals, e-commerce checkouts and mobile payments all sit in PCI DSS scope. You map card flows, segment payment systems and shrink that scope, so audits cost less and a breach reaches less.
Customer data at scale
Loyalty schemes, customer accounts and marketing lists hold large volumes of personal data. You control access, encrypt what matters and meet UK GDPR duties, so a breach does not become a story about your customers.
A supply chain you do not control
Vendors, franchisees and logistics partners connect to your systems. You assess third-party access and set clear requirements, so someone else's weak password does not become your incident.
In store and online, covered together
Attackers do not care whether they get in through a shop-floor till or a website plugin. Your physical and digital estates share networks, accounts and data, so they need securing as one. Here is what that covers.
One approach across every channel
Physical estate
- Point of sale (POS) terminal hardening and malware defence
- Payment networks segmented from everything else
- Store Wi-Fi kept separate from payments
- Staff procedures for fraud and card skimming
- Back-office PCs and devices managed and patched
Digital estate
- E-commerce platform testing and web application firewall (WAF)
- Checkout scripts and payment gateway checks
- Account takeover and fraud prevention
- Cloud and hosting security
- Peak-season readiness reviews
In store, that means endpoint management for tills and back-office devices, and staff training your shop-floor teams will remember. Online, it means application security and penetration testing of your checkout, plus cloud security for the platforms behind it. Tighter identity and access controls protect both.
Compliance that clears the acquirer
Your payment provider asks every year. You answer once, with evidence:
PCI DSS v4.0
Scoping, gap assessments and remediation across tills, e-commerce and call centres, including payment page script controls.
UK GDPR
Loyalty data, marketing consent and the 72-hour breach reporting duty handled properly.
Cyber Essentials
A recognised baseline across stores and head office that suppliers and buyers can check.
Staff readiness
Till teams trained on fraud, skimming and social engineering, then tested, not just told.

How an engagement runs
We start by mapping where card and customer data flows across your stores, website and suppliers. Then we test your defences against realistic retail attacks, fix what matters first and package the results as evidence your acquirer and auditors will accept.

Card payments raise similar questions for financial services firms. If your stores sit in a wider property portfolio, see how we support real estate businesses, and if you invest in retail brands, our private equity page covers due diligence. All of our framework work sits within our governance services.
