E-commerce at a Glance
Why E-commerce Security Is Non-Negotiable
E-commerce platforms process payments, store customer data, and depend on web application availability — making them targets for payment fraud, data theft, and application-layer attacks.
Payment Page Attacks
Magecart-style attacks inject card-skimming code into checkout pages, harvesting payment data in real time without touching your servers. Third-party scripts — analytics, chat widgets, marketing tags — create supply chain attack vectors that traditional server-side security controls do not detect.
Customer Account Security
Credential stuffing, account takeover, and session hijacking target customer accounts containing saved payment methods, order history, and personal data. A single compromised account can lead to fraudulent purchases, data exposure, and brand trust erosion at scale.
PCI DSS Compliance Complexity
Card networks require PCI DSS compliance for all merchants accepting card payments. Determining the correct SAQ type, understanding scope boundaries, and maintaining compliance through continuous platform updates demands specialist QSA guidance — not generic IT consulting.
Services for E-commerce Platforms
Every service below has been delivered to e-commerce businesses — online marketplaces, subscription platforms, direct-to-consumer brands, and digital payment merchants.
PCI DSS Compliance
Scoping assessments to determine the correct SAQ type, gap analysis and remediation guidance, and formal validation by EIC's certified QSA team. CardIntel maps your payment flows to define scope boundaries precisely, identifying integration changes that can reduce compliance effort.
Web Application Penetration Testing
CREST-accredited testing targeting e-commerce attack vectors: payment page manipulation, business logic flaws in pricing and inventory, authentication weaknesses, API vulnerabilities, and third-party JavaScript supply chain risks. Satisfies PCI DSS Requirement 11.4.
CardIntel Platform
Automated discovery of cardholder data across your platform — databases, logs, API payloads, cached responses, and third-party integrations. Identifies scope reduction opportunities that lower PCI DSS compliance cost and timeline for e-commerce platforms.
ISO 27001 Certification
ISO 27001 provides the framework to protect customer data — personal information, order history, saved payment methods — and demonstrates security commitment to customers, partners, and enterprise buyers. Dual certification with PCI DSS saves 20–30%.
Which PCI DSS SAQ Applies to Your E-commerce Platform?
The correct Self-Assessment Questionnaire depends on how your platform handles card payments. EIC determines the right type during the free scoping call.
| SAQ Type | Payment Integration | Scope | Typical E-commerce Use |
|---|---|---|---|
| SAQ A | Fully outsourced — redirect or hosted iframe | Lowest scope — ~20 requirements | Shopify, hosted checkout, payment provider redirect |
| SAQ A-EP | Website influences transaction security but does not process card data | Medium scope — ~140 requirements | Custom checkout with embedded payment form, JavaScript-based tokenisation |
| SAQ D | Direct card data processing, storage, or transmission | Full scope — ~300+ requirements | Custom payment processing, stored card functionality, recurring billing with direct integration |
| ROC | Any — required for Level 1 merchants (6M+ transactions/year) | Full scope — formal QSA assessment | High-volume marketplaces, large-scale e-commerce platforms |
Online Marketplace — PCI DSS + Web App Security
Regional E-commerce Marketplace — Southeast Asia
A fast-growing online marketplace with 500,000+ monthly transactions needed PCI DSS compliance to onboard a major payment processor and expand to two new markets. The platform used a hybrid payment integration — a custom checkout page with client-side tokenisation — that initially appeared to require SAQ D (full scope).
EIC's scoping assessment identified that a minor architecture change — migrating from client-side tokenisation to the payment provider's hosted iframe — would shift the platform from SAQ D to SAQ A-EP, reducing scope by approximately 40%. The web application penetration test uncovered 8 critical findings including a business logic flaw that allowed price manipulation on bulk orders. Both PCI DSS compliance and remediation of critical findings were completed within 14 weeks.
