Your checkout is your revenue. Payment flow security, PCI DSS compliance, cart manipulation testing, account takeover prevention and customer data protection — tested by specialists who understand how online stores process transactions, handle sensitive data and scale during peak traffic.
// The Challenge
Attackers follow the money. Your platform processes payments, stores customer PII, manages inventory pricing and integrates with third-party gateways. A single vulnerability in the checkout flow can mean stolen card data, fraudulent orders, regulatory fines and permanent loss of customer trust.
Your store handles payments, personal data and high-value transactions around the clock. Every layer from checkout to fulfilment is a potential breach point.
Flaws in payment flows — price tampering, coupon abuse, race conditions at checkout — let attackers purchase goods at manipulated prices or exfiltrate cardholder data mid-transaction.
Automated credential stuffing and weak authentication controls let attackers hijack customer accounts, drain stored payment methods and abuse loyalty points at scale.
Attackers modify cart quantities, inject negative values, abuse discount logic or manipulate client-side pricing to complete orders at a fraction of the actual cost.
Ecommerce platforms store names, addresses, phone numbers and payment details. A data breach triggers regulatory fines, class-action risk and irreversible brand damage.
Payment gateways, fraud detection services and hosted checkout pages extend your trust boundary. A misconfigured integration can expose cardholder data or bypass fraud controls entirely.
Shipping APIs, inventory management systems, analytics scripts and marketing pixels — each third-party integration is a potential entry point for supply-chain attacks like Magecart-style skimming.

The mandatory standard for any business handling cardholder data. We test against all applicable requirements, validate network segmentation and prepare SAQ or ROC evidence for your QSA.
Enterprise and marketplace partners increasingly require SOC 2 reports. We map your controls to Trust Services Criteria and prepare evidence packages for audit readiness.
Selling to EU customers means GDPR compliance. Data processing inventories, consent mechanisms, privacy impact assessments and technical controls for customer data protection.
Strong Customer Authentication requirements for European payment transactions. We validate your 3D Secure implementation, exemption handling and transaction risk analysis mechanisms.
Required by enterprise retail partners and global marketplace integrations. We run gap analysis and build ISMS documentation to achieve certification readiness.
For Indian ecommerce platforms: compliance with RBI data localisation mandates, payment aggregator guidelines and cybersecurity framework requirements for digital payment operators.
