PCI Compliance Made Simple
Keep card data off your server and it becomes much simpler.
Most WooCommerce stores qualify for the lightest PCI self-assessment once payments are configured so cardholder data goes straight to Stripe or PayPal. We set that up, clean the scripts off your checkout page, and harden what’s left.
Our approach
Getting out of scope beats passing an audit.
PCI DSS (Payment Card Industry Data Security Standard) applies to any business that stores, processes, or transmits cardholder data. The key word is “transmits.” If card data passes through your server at any point during checkout, your server is in scope, which means security controls and periodic audits.
The right approach for most WooCommerce stores is not to achieve PCI compliance. It’s to configure payments so that cardholder data never reaches your server at all. When you use Stripe Elements, PayPal Express, or another hosted payment solution correctly, the payment form is served by Stripe or PayPal (not your server), and the card number is tokenized by their PCI-compliant systems before your checkout ever sees it.
That puts you in SAQ A or SAQ A-EP, the lightest PCI scope levels, and where most small and mid-size WooCommerce stores can legitimately sit. Which of the two depends on how your payment fields are served and what else runs on your checkout page. We configure your payment setup to achieve this.
What we do
Payment security implementation for WooCommerce.
Stripe Elements or PayPal Express setup
Configure WooCommerce to use hosted payment fields that collect card data on Stripe’s or PayPal’s servers, not yours. Correct configuration keeps you out of full PCI scope.
SSL and HTTPS configuration
Valid SSL certificate across your entire domain, HSTS configuration, mixed content elimination, and HTTPS enforcement. Required for all payment pages and a baseline PCI requirement.
WordPress security hardening
File permission hardening, WordPress security keys rotation, database prefix change, admin URL obscuration, two-factor authentication, and WAF configuration. The security baseline that supports a defensible PCI posture.
Plugin audit and removal
Since March 2025, qualifying for the lightest PCI questionnaire means confirming your checkout page runs no scripts that could compromise it. A typical WooCommerce store runs twenty to forty plugins, and several inject scripts at checkout. We audit every active plugin against what it does and whether the checkout needs it.
Security monitoring setup
Wordfence or Sucuri configuration with file change monitoring, login attempt logging, and malware scanning. Alert thresholds set so your team is notified of suspicious activity rather than discovering it months later.
Security documentation
A documented record of security controls implemented, the evidence a payment processor or an enterprise buyer’s security team asks for.
PCI SAQ levels
PCI SAQ levels explained
SAQ-A
All payment elements served directly by a PCI DSS compliant provider, and a checkout page free of scripts that could compromise it. Card data never reaches your server. Lightest form.
SAQ-A-EP
Payment fields on your page that fall short of the SAQ A criteria, usually because of what else runs at checkout. Card data still goes to the provider rather than your server, but the questionnaire is substantially longer.
SAQ-D
Card data passes through or is stored on your server. Custom payment forms, older WooCommerce setups, or any integration without tokenization. Full assessment.
We configure payment setups to SAQ-A or SAQ-A-EP. Formal PCI certification requires a Qualified Security Assessor (QSA). We're WordPress developers, not QSAs.
Our process
How a payment security engagement works.
01
Payment flow review
We audit how card data moves through your checkout and which SAQ level your store actually falls under, before recommending any changes.
02
Fixed quote
We scope the gateway configuration and hardening your store needs and quote a fixed price before starting. Most stores need configuration, not an overhaul.
03
Implement
Hosted payment fields, SSL and HTTPS enforcement, WordPress hardening, plugin cleanup, and security monitoring, applied and tested before they touch your live checkout.
04
Verify and document
We verify the setup and deliver a documented record of the security controls, the evidence you need to complete your self-assessment questionnaire confidently.

Common questions
PCI compliance questions for WordPress stores.
It depends on how payments are configured. If your checkout uses Stripe or PayPal with the card field served from their domain, card data never touches your server and you’re in the lightest scope. If the card field is a plain input on your own domain, that needs fixing. Either way we audit the payment flow first and tell you which questionnaire you actually fall under before recommending changes.
Stripe is our first recommendation for most WooCommerce stores: excellent developer tooling, Stripe Elements implementation that keeps you in SAQ A scope, strong fraud tools, and a WooCommerce plugin that’s actively maintained. PayPal via the official PayPal Payments plugin is a good second option and the preferred payment method for a meaningful segment of shoppers. For stores needing specific features (ACH payments, Buy Now Pay Later, B2B invoicing), Authorize.Net, Braintree, and Square each have WooCommerce integrations we’ve implemented. We recommend against lesser-known gateway plugins with infrequent updates.
Most small to mid-size WooCommerce stores can self-certify at SAQ A or SAQ A-EP level without a QSA. A QSA is required for Level 1 merchants (over 6 million transactions/year) or merchants whose payment processor specifically requires an on-site audit. If you’re below Level 1 volume thresholds, you complete a Self-Assessment Questionnaire annually and submit it to your payment processor. We implement the technical controls; the SAQ is your documentation that those controls are in place.
It depends on your current setup and payment flow: whether card data ever touches your server or stays with a hosted gateway, how many payment methods and checkout plugins you run, and the hardening your hosting needs. Most stores that use a hosted gateway need configuration and hardening rather than a costly overhaul, and we scope the exact work before quoting.
Four things. Use a hosted gateway so card data goes straight to Stripe or PayPal. Clear the scripts off your checkout page that would disqualify you from the lightest questionnaire. Enforce SSL across the domain. Harden access and keep everything patched. The self-assessment questionnaire comes last, and it’s shorter when the first four are done.
It shrinks the job, and it doesn’t finish it. You still complete a self-assessment questionnaire annually and keep the site secure. Since March 2025 the lightest questionnaire also requires confirming your checkout page carries no scripts that could compromise it, which is a WordPress question rather than a Stripe one.
Your processor can levy monthly non-compliance fees, raise your transaction rates, or suspend the merchant account. If card data is breached while you’re non-compliant, liability for the fraud and the forensic investigation lands on you rather than being shared.
Yes, through the maintenance plans. Compliance is an annual questionnaire resting on controls that have to hold all year: patching, monitoring, access control, and checkout scripts staying clean as you add plugins. The same controls that satisfy PCI are the ones that stop ordinary attacks, so it’s one job rather than two.
Find out which questionnaire you actually fall under.
We trace how card data moves through your checkout, identify your real SAQ level, and hand you the gap list. Most stores are closer to the lightest form than they expect.
