E-commerce & retail

Account takeover, promo abuse, and payment-flow gaps are costing e-commerce teams real money before a single auditor asks a question.

We test the abuse paths that eat margin and damage customer trust — ATO flows, promo and cart logic, payment integrity, and PCI DSS coverage — before a chargeback spike or audit deadline forces the issue.

What is at stake

Four situations retail teams are navigating right now.

Account takeover

Credential stuffing and ATO are eating customer support and chargebacks. You need to test resistance.

Promo and cart abuse

A promo campaign lost more money than expected, or a checkout flow has unexpected paths.

PCI DSS

You hold or process cardholder data and need documented testing on a defined cadence.

Peak-season hardening

A holiday or product launch is approaching and you want a clean test before traffic spikes.

How we help

We test the six surfaces that hurt retail teams most — from ATO to payment-flow integrity.

Every finding comes with a working proof and a remediation engineers can act on. PCI DSS control mapping is included where cardholder data is in scope.

Account takeover paths

Login throttling, MFA bypass, credential stuffing resistance, account-recovery flows, device binding.

Promo and discount logic

Coupon stacking, referral abuse, gift-card double-spend, subscription re-upgrade paths.

Payment flow integrity

Cart tampering, price manipulation, partial-refund abuse, idempotency and retry safety.

Customer-data exposure

Order history, addresses, partial card data, PII in logs and exports, support-agent access.

Storefront and CMS

Theme-injection, third-party script supply chain, admin endpoints exposed to the public storefront.

Mobile and partner APIs

In-app purchase flows, partner integrations, fulfillment APIs, webhook signature handling.

How an engagement works

Four steps from scoping call to a report your processors and partners will accept.

  1. 01

    Scoping call

    A quick call. We learn your checkout flows, CDE boundary, and what is driving the test — a chargeback spike, PCI audit, or peak-season deadline. You leave with a fixed scope, price, and date.

  2. 02

    Hands-on testing

    A senior tester runs the engagement end-to-end across account flows, promo logic, payment paths, and storefront surfaces. Critical findings surfaced immediately on a live channel.

  3. 03

    Report you will read

    Every finding has a working proof and a remediation engineers can act on. PCI DSS control mapping included where cardholder data is in scope. One-page board summary included.

  4. 04

    Retest included

    We retest fixed items and update the report at no extra cost. The version you share with your payment processor or partner reflects your actual fixed state.

Peak season or PCI deadline approaching?

A quick scoping call gives you a fixed scope, price, and date — so the test lands before traffic spikes or the audit window closes.

FAQ

E-commerce — common questions

Do you cover PCI DSS for e-commerce?

Yes. External and internal testing per PCI DSS Requirement 11.4 and segmentation testing per 11.4.5 where the cardholder data environment shares infrastructure with out-of-scope systems.

How do you test promo and cart abuse safely?

We default to a staging environment with realistic catalog and pricing data. When production testing is necessary, we agree explicit safe-testing rules and stay reachable on a shared channel throughout.

Can you test our mobile checkout flow?

Yes. Mobile clients and the APIs they call are standard scope — in-app purchase flows, partner integrations, and the payment path end-to-end.

How do you test account-takeover resistance?

We test login throttling, MFA bypass paths, account-recovery safety, device binding, and support-agent overrides — the specific abuse paths a real ATO attempt would take.

Will the report support our payment processor or partner reviews?

Yes. Reports include the explicit scope statement and PCI DSS mappings that processors and platform partners typically request in vendor reviews.

Want a credible answer when a customer, auditor, or your board asks how secure you are?

A quick scoping call with the senior tester who would run your engagement. No slides, no pitch — we look at what you have, tell you what we would test first, and give you a fixed scope, price, and date.
