Penetration Testing for
E-commerce

Online stores process customers’ personal data, payment card information, and handle financial transactions. A data breach leads to loss of customer trust, GDPR fines (up to EUR 20 million), chargeback liability, and reputational damage. Penetration testing detects vulnerabilities before cybercriminals can exploit them.

Yes. PCI-DSS Requirement 11.3 mandates penetration testing at least once a year and after every significant change to the infrastructure or application handling payment card data. Tests must cover both the network and application layers.

We test all major platforms: Magento (Adobe Commerce), WooCommerce, PrestaShop, Shopify, Shoper, IdoSell, Wix, BigCommerce and custom e-commerce solutions built on Laravel, Symfony, Django, or Node.js. We have experience testing both standard installations and heavily customized versions.

The duration depends on the store’s size: small WooCommerce/PrestaShop store (3-5 days), mid-sized store with customizations (5-8 days), large Magento platform/marketplace (10-15 days), store plus mobile app (7-12 days). For stores with integrations (ERP, WMS, couriers) the timeline may extend by 2-4 days.

Yes, we typically test the production environment during low-traffic hours (e.g., nighttime, early morning) using techniques that are safe for store operations. We avoid DoS tests and actions that could affect availability. Alternatively, we can test a staging/dev environment if it is identical to production.

We test: authorization and authentication, payment processes and gateway integrations, shopping cart and checkout flow, admin panel, discount and promotion mechanisms, APIs (REST/GraphQL), third-party plugins and modules, anti-fraud mechanisms, OWASP Top 10, business logic flaws (price manipulation, payment bypass).

Yes. We test integrations with: PayU, Przelewy24, Stripe, PayPal, Dotpay, Tpay, Paynow, Adyen, Klarna. We verify the correctness of payment protocol implementation, protection against replay attacks, signature validation, callback handling, and compliance with provider documentation.

Yes. We offer PCI-DSS compliance audits covering all 12 requirements of the standard. We deliver detailed reports compliant with QSA (Qualified Security Assessor) requirements, identify areas of non-compliance, and advise on remediation. We can also help prepare for PCI-DSS certification.

Yes. We specialize in detecting business logic flaws such as: product price manipulation, reuse of discount codes, order limit bypass, loyalty program abuse, race conditions in payments, and cart amount manipulation. These are often the most costly vulnerabilities for e-commerce.

The report includes: executive summary for management, detailed description of vulnerabilities with CVSS risk ratings, proof-of-concept (screenshots, HTTP requests), step-by-step remediation recommendations, mapping to OWASP Top 10 and PCI-DSS, prioritization of fixes, and testing timeline. Format: PDF plus optionally Excel with a vulnerability list for tracking in JIRA/Redmine.
