The Problem

Your Store Was Built to Sell, Not to Keep Thieves Out

It shows up when your payment provider flags card testing, a customer reports a strange charge, or an old app still reads your orders.

  1. Old access

    Former staff and agencies still hold admin logins.

    Old access

    Every account is reviewed, then protected with two-step verification or removed.

  2. Card testing

    Bots test stolen cards on your checkout overnight.

    Card testing

    Rate limits, bot challenges, and gateway rules stop repeat attempts from one source.

  3. Cart scripts

    Nobody knows which scripts run on the cart page.

    Cart scripts

    Each cart and checkout script gets an owner and a change alert.

  4. App access

    Apps you uninstalled can still read your orders.

    App access

    App permissions and API keys are checked, trimmed, or revoked.

Your store still has staff logins for people who left, and an agency you stopped paying keeps admin access. A long list of apps can read your orders and customers. Then your payment provider emails about hundreds of small declined charges overnight: someone used your checkout to test stolen cards. A week later, a customer asks why their card was used somewhere else after buying from you. Nobody can say which scripts load on your cart page, or who added them.

We start with the five ways into a store: staff access, apps, checkout scripts, payment settings, and customer data. Every staff login gets two-step verification, and old access comes out. Each script on your cart and checkout pages gets an owner and a change alert. Card testing meets rate limits and gateway rules. The next stolen card hits a limit on your checkout, not your payment account.

  • Every login has an owner

    Staff, agency, and app access is listed, trimmed, and protected with two-step verification.

  • Checkout scripts under watch

    Scripts on cart and payment pages get owners, and any change sends an alert to our team.

  • Card testing slowed at checkout

    Rate limits, bot challenges, and gateway rules make stolen card runs fail fast.

Our Ecommerce Security Services Process

From Store Risk Check to Locked-Down Checkout in Five Clear Steps

You see the access list, the script list, and every fix before it goes live, and you approve each change to staff logins and payment settings.

  1. We look at your platform, plan, apps, and checkout from the outside, then ask a few questions about staff and payments. You get a risk note and a fixed price. If your platform's built-in settings already cover a small store, we'll tell you before we quote.

Projects We've Built

Stores with catalogs, carts, and customer accounts that we designed and built. They weren't security projects, but they show the admin areas and checkouts this work protects.

What's Included

What You Get With Our Ecommerce Website Security Work

An access review, an app and API key cleanup, a checkout script inventory with change alerts, card testing defenses, customer account protection, and a recheck with handover notes.

  • Staff and agency access review

    Every account and role checked, unused logins removed, and two-step verification turned on for the rest.

  • App and API key cleanup

    Apps, plugins, and API keys cut back to the access they need, or revoked when nobody uses them.

  • Checkout script inventory

    Every script on cart and checkout pages listed with an owner, plus an alert whenever one changes.

  • Card testing defenses

    Rate limits, bot challenges, and gateway rules that make stolen card runs fail before fees pile up.

  • Customer account protection

    Login rate limits and bot checks that slow credential stuffing against your customers' accounts.

  • Recheck and handover

    Every fix retested, with the access list, the script list, and a runbook for adding apps safely.

What Our Clients Say

What Clients Say After Launch

Feedback from teams we have built stores, apps, and websites for.

We had a pretty specific idea of what we wanted our website to become, but I wasn’t sure how easily we could explain all of it to a development team. There were quite a few moving parts, and we were working toward a deadline, so I expected a few things to get lost along the way. That never really happened. They understood what we were trying to achieve, kept us updated throughout the process, and got everything ready within the agreed timeline. The final site feels much easier to navigate, works beautifully on mobile, and is noticeably smoother for our customers. It was a huge relief seeing the original idea actually turn into the website we had in mind.

Work Culture

Why Store Owners Trust Us With Ecommerce Cyber Security

Stores lose sales when security work is rushed. These habits keep orders flowing while access gets tighter and checkout scripts stay watched.

  • Checkout keeps taking orders

    We place a test order after every change to checkout, payments, or login rules. A fix that blocks real customers isn't a fix, so it rolls back.

  • Access removed, not just listed

    We don't hand you a list of stale logins and leave. With your approval, we remove them, rotate the keys, and confirm your apps still work.

  • Honest advice per platform

    Shopify and BigCommerce run your servers and core checkout, while WooCommerce and Magento stores own theirs. We secure the part that's actually yours instead of selling everyone one package.

  • Plain answers on PCI

    We explain how your checkout setup affects PCI DSS scope, then say plainly that your bank or assessor makes the call. We don't promise compliance.

  • Every change written down

    Each fix lands in a change log with the date, the reason, and how to undo it. Your next developer or auditor can follow it.

  • Your accounts, your keys

    Admin access, API keys, and alert inboxes stay in your name. When we finish, our own access comes out too, and you confirm it.

Good fit

  • Shopify stores with many staff and apps

    Your Shopify store has years of staff accounts and apps with order access, and you want security for ecommerce that starts with who can log in.

  • WooCommerce stores on their own hosting

    Your WooCommerce store runs on a server you manage, and a plugin flaw in the news made you wonder what else is open.

  • Stores hit by card testing

    Your payment provider flagged a burst of small declined charges, and you need card testing stopped before it costs you fees or your merchant account.

  • Teams running several storefronts

    Your team runs stores on BigCommerce and Magento and wants one standard of security for ecommerce websites across every brand.

  • Agencies managing client stores

    Your agency looks after client stores and wants a security review you can deliver under your brand before peak season.

Not a fit

  • Need a PCI compliance program

    You need your SAQ chosen, policies written, and evidence gathered for your bank. Our PCI Compliance Services cover that program, and this page stays with technical fixes.

  • Magento store behind on patches

    Your main worry is a Magento or Adobe Commerce store missing security releases. Our Magento Security Patches and Audit service handles patching and skimmer cleanup.

  • Only want a written audit

    You want findings for your own developers to fix. Our Website Security Audit Services deliver a ranked report from $450.

  • Tiny store, one login

    You sell a handful of products on a hosted plan with one login and no apps. Your platform's two-step login and default fraud settings are enough for now.

FAQ

Frequently Asked Questions

Straight answers on cost, timing, customer data, payment gateways, card testing, and PCI.

  • Ecommerce security services from DeveloperLook start at $950 for one store. That covers the review, two-step verification on every staff login, stale access removed, and 30 days of script alerts. The $2,250 plan fixes every high and medium finding. The $4,400 plan covers up to 3 stores or a self-hosted server, plus a firewall.

  • A security review of one store takes 1 to 2 weeks, and a review with every fix takes 3 to 6 weeks. Checkout changes take longest because we place test orders after each one and avoid your busiest sales hours. Several storefronts or your own servers put you at the top of that range.

  • You secure an ecommerce website by closing the five ways in: staff logins, apps, checkout scripts, payment settings, and customer data. Good security for ecommerce website owners starts with two-step verification on every admin account. Next, remove apps and API keys nobody uses. Then list every script on the cart and checkout, and set gateway rules that slow card testing.

  • Ecommerce security protects customer data by limiting who and what can read it, and by keeping card numbers off your systems. Hosted payment fields or a redirect to the gateway mean card data doesn't pass through your server. Customer exports get locked to named staff, apps lose order access they don't need, and customer logins get rate limits against credential stuffing.

  • Start with the threats aimed at online stores: stolen staff logins, card testing, skimming scripts, and risky apps. Off-the-shelf ecommerce security solutions such as security apps help with scanning, but they can't decide who should have access. Turn on two-step verification, remove unused apps, and watch your checkout scripts for changes.

  • Choose a gateway that keeps card data off your site and gives you fraud controls you can tune. Look for hosted payment fields or a hosted checkout, 3D Secure support, and rules that block repeated declines. Stripe, PayPal, Braintree, and Adyen all offer these, so the right pick depends on your platform and markets.

  • Shopify isn't more secure for every store, but it takes more of the work off your hands. Shopify and BigCommerce run the servers and core checkout, and Shopify runs custom pixels in a sandbox without access to the checkout page itself. On WooCommerce and Magento you own the server, patches, and plugins too. Either way, staff logins and apps stay your job.

  • You stop card testing by making repeated attempts from one source slow and costly. We add rate limits on checkout and payment requests, a bot challenge when attempts spike, and gateway rules that block repeated declines. Stripe Radar, for example, supports custom rules for repeated attempts.

  • No, security work alone doesn't make a store PCI compliant, because your acquiring bank or a Qualified Security Assessor decides that. We fix technical gaps that PCI DSS reviews often raise, such as shared admin logins and unknown payment page scripts. For the full program with scoping and evidence, our PCI Compliance Services page covers readiness work.

  • Every plan includes 30 days of checkout script change alerts and fix support after handover. When a script changes, we check who made the change and remove anything that shouldn't be there. After that, run the alerts yourself with our runbook, or move to a monthly plan on our Website Security Monitoring page.
