Assurance for retail, e-commerce and payments
Protecting payments, customers and the storefront.
Retail and e-commerce run on customer trust and payment integrity across platforms you partly outsource. We assess payment security, customer-data protection and platform resilience — clarifying which payment obligations actually apply to you rather than assuming all of them do.

Business context
Retailers and e-commerce businesses process payments and large volumes of customer data across web, app and third-party platforms. Payment-security obligations depend on how you handle card data, so scoping applicability is the first step.
Major cyber & governance challenges
What the sector is up against.
Payment security
Card data and payment flows carry PCI DSS obligations where in scope.
Customer-data protection
Large volumes of personal data under privacy obligations.
Platform & application security
Web and app storefronts are high-value attack targets.
Third-party payment integrations
Gateways, processors and plugins extend the risk surface.
Peak-season resilience
Availability during peak trading is business-critical.
Relevant regulatory landscape
What may apply — and to whom.
PCI DSS
Details →Where you store, process or transmit card data — scope varies by how you handle it.
Applicable privacy laws
Details →Customer-data protection under the relevant regime.
Payment-sector rules
Details →Jurisdiction-specific (e.g. RBI payment requirements in India).
ISO/IEC 27001
Details →Voluntary security management baseline.
Applicability is organisation-specific. This is general information, not a legal determination — we confirm what applies to you during scoping. See the Framework Library for sources and classifications.
