Penetration testing for e-commerce

A vulnerable checkout costs far more on Black Friday than on any other day of the year.

Penetration testing for online stores and marketplaces, covering checkout, customer accounts, payment gateway integrations and infrastructure ahead of seasonal peaks like Black Friday.

When this matters

E-commerce concentrates money, customer data and variable traffic in one flow.

Unlike an ordinary SaaS, the technical risk of an online store ties directly to financial transactions, loyalty programs, coupons and integrations with gateways and marketplaces — flaws there do not just create a security incident, they create fraud and direct loss. Peak dates like Black Friday multiply both the traffic volume and the incentive for an attacker to exploit any gap.

Coverage

What we assess in an online store or marketplace.

The scope combines web application, API and infrastructure according to the platform's architecture.

Checkout and pricing rules

Manipulation of amounts, coupons, shipping, payment terms and the step sequence of the purchase flow.

Accounts and loyalty

Payment and marketplace integrations

Webhooks, callbacks and order synchronization with gateways, marketplaces and back-office systems.

Infrastructure under peak traffic

Asset exposure, configuration and services that become more critical as access volume rises.

Process

A schedule designed to fit before code freeze.

We recommend starting far enough ahead to fix issues and still validate before the peak date.

Define the pre-peak scope

We prioritize checkout, payment and the flows expected to carry the most traffic on the critical date.

Run against a stable environment

The test targets the version that will actually be in production during the peak period.

Prioritize by commercial urgency

Critical findings in the purchase flow are prioritized so they can be fixed before code freeze.

Retest before the target date

We validate the applied fixes with enough time left that no untested last-minute change slips in.

Deliverables

A result that protects revenue, not just data.

The delivery connects technical findings to the financial and reputational impact an incident would cause during peak sales.

Checkout validated before the peak

Confidence that the purchase flow holds up against manipulation attempts during the highest-revenue period.

Security

Remediation prioritized by the time window

Findings organized around the time remaining until the critical date.

Fraud prevention

Signals to strengthen adjacent controls

Vulnerabilities that could be combined with fraud are flagged for the team responsible for prevention.

Ask on WhatsApp

How far ahead of Black Friday should I book the test?+

Ideally you leave enough time for execution, remediation and a retest before code freeze — usually several weeks before the target date, depending on the size of the scope.

Does the test cover payment fraud?+

It identifies technical vulnerabilities that could be exploited for fraud, such as price manipulation or coupon abuse, but it does not replace fraud or chargeback analysis, which are complementary disciplines.

Is the third-party payment gateway in scope?+

The gateway itself is normally the provider's responsibility. The scope covers how your store integrates with it and how it validates and reacts to its responses and callbacks.

Do we need to stop deploying during the test?+

It is not mandatory, but we recommend limiting significant changes during the execution window so findings reflect the version that will actually be in production at the peak.

Next step

Facing a seasonal sales peak?

Tell us the target date, the store's architecture and the payment integrations so we can build a schedule that fits before the peak.
