Checkout and payment flow
Gateway configuration, checkout page scripts and third-party tags, injected-skimmer exposure, HTTPS integrity, and what actually touches payment data in this store.
WooCommerce security audit
WooCommerce Security Audit: protect the checkout, the orders, and the customer data.
A store is not a brochure site with a cart bolted on. It moves money, stores customer personal data, runs privileged roles, and depends on a stack of payment, shipping, and marketing extensions. This audit reviews the WooCommerce store as the commercial system it is — from checkout scripts to recovery of order data.
Never send credentials, private keys, backup archives, or confidential source code through this website.

Why stores are different
A compromised store loses more than a defaced page
Attackers treat WooCommerce differently because the payoff is different. A compromised brochure site serves spam; a compromised store can leak customer records, skim payment details at checkout, redirect completed-order traffic, farm coupon and refund abuse, or quietly harvest the credentials of returning customers.
The store also carries obligations a brochure site does not: customer personal data under privacy law, payment-brand requirements flowing through the gateway, and the commercial reality that even an hour of broken checkout is measurable lost revenue. The audit is scoped around those stakes.
In the ClickFix incident documented in our published report, WooCommerce sites were among the 30+ compromised — with fake verification panels interrupting shopping journeys at exactly the moment customers were asked to trust the site most.
Scope
What the WooCommerce audit examines
Everything in the WordPress security audit is included; these are the store-specific layers on top.
Customer accounts and roles
Customer, shop manager, and custom role boundaries; account takeover exposure on login, registration, and password recovery; session handling for returning buyers.
Extensions and integrations
Payment, shipping, tax, marketing, and analytics plugins; stored API keys and webhooks; the vulnerability exposure and update posture of each commercial extension.
Order and customer data
Where personal data lives and leaks — order exports, logs, email content, admin screens, staging copies — and who can reach it.
Store business logic
Coupon and discount abuse, price and cart manipulation, refund and stock workflows, and subscription or membership entitlement boundaries.
Operational and recovery controls
Backup and restoration readiness for a dataset that changes with every order, staging discipline, update workflow, and incident contacts.
Payment security, honestly
What this audit is — and is not — for card data
Most WooCommerce stores offload card handling to a hosted gateway, which keeps raw card data off the server. That reduces scope but does not remove risk: a compromised checkout page can still skim card details in the browser before the gateway ever sees them, which is why checkout-script integrity is part of this audit.
This engagement is an independent security audit, not a PCI DSS assessment by a Qualified Security Assessor. It supports the security controls behind a self-assessment questionnaire and will say clearly which requirements it does and does not evidence — an honest boundary an insurer or acquirer can rely on.
Method
Assessment without endangering the store
- 01
Scope around the business
Identify peak trading windows, the gateway and fulfillment integrations, test-order rules, and what must never be touched — before any access is exchanged.
- 02
Inspect and validate
Review external exposure and approved internal controls, using test accounts and agreed test orders. Potential issues are manually verified before they are reported.
- 03
Prioritize by store impact
Findings are ranked by what they mean for this store — checkout integrity first, data exposure second, hardening opportunities after — with the responsible party named.
- 04
Remediate and retest
Implement agreed fixes directly or support your developer, then retest the affected behavior — including a checkout walk-through — and update the report.
Common questions
Questions about this engagement
Is this a PCI compliance certification?
No. It is an independent security audit that strengthens and evidences the controls behind your gateway setup and self-assessment. It does not replace a QSA assessment where one is required, and the report states that boundary explicitly.
Can you audit a live store without breaking checkout?
Yes. Trading windows, test-order rules, and prohibited actions are agreed during scoping, and nothing destructive is performed. Most of the review is observational; anything interactive uses agreed test accounts.
Do you cover subscriptions and memberships?
Yes, when they are in scope. Recurring billing, entitlement boundaries, and cancellation flows are reviewed as business logic, since that is where stores quietly lose money.
How much does a WooCommerce security audit cost?
It follows the WordPress security audit range of $150–$500, with stores typically landing in the upper half or above it depending on extensions, integrations, and subscription complexity. The proposal states the exact fixed fee.
We already had the plugin stack reviewed. Is this redundant?
A plugin review covers one layer. This audit also examines checkout scripts, roles and sessions, data exposure, business logic, and recovery — the layers where store-specific losses actually occur.
