LET'S DISCUSS
We had a different kind of problem. People were visiting the store, adding products to their carts, and then disappearing before they finished the order. We had tried a few apps and made changes here and there, but nothing really seemed to solve the bigger issue. The team went through the shopping experience with us and pointed out things we hadn't really noticed ourselves. They cleaned up the cart and checkout flow, made the mobile experience much smoother, and helped us make the store feel easier to shop. I’m not going to pretend we fixed everything overnight, but it finally feels like the store is helping the sale instead of getting in the way of it.
Ethan Parker
Founder of Elite Academy
The mobile experience is probably my favourite part of the new site. We had spent a lot of time making sure the desktop version looked right, and the team kept pushing us to think about how everything would actually feel on a phone too. They were right. The navigation is clean, the interactions feel natural, and everything we’ve tested so far works exactly as it should. They also went through the links, forms, integrations, and other details more than once before launch, which I really appreciated. And even after going live, we could still reach out when something came up. The whole process felt friendly, organised, and surprisingly straightforward.
James Whitmore
Head of Marketing of Lumen Outdoor
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.

07Work Culture
Why Store Owners Trust Us With Penetration Testing
Testing a live store needs discipline, so we agree the rules before we start. These are the habits we bring to every penetration testing engagement.
Written scope first
We only test what you have authorized, in windows you agree.
Real attack paths
We test checkout, payments and logins the way attackers do.
Scored findings
CVSS scores help you prioritize.
Actionable fix list
Each finding tells your developers what to change.
Free retest
We verify your fixes once they are done.
Clear starting price
Standard storefronts have a set starting price.
08Overview
What's the difference between a vulnerability scan and a penetration test, and what does it cost?
DeveloperLook's penetration testing simulates real attacks on your checkout, payment flows, custom Shopify apps, and account logins using gray-box access similar to a real customer's view. Every finding gets CVSS scoring, reproduction steps, and a fix list, plus a free retest once fixes are in place. Standard ecommerce testing starts at $2,999, well below the $20,000+ enterprise SaaS engagements industry benchmarks cite for source-code review.
- Starting price
- From $2,999 for a standard WooCommerce or Shopify storefront
- Typical timeline
- 1-2 weeks of active testing for a standard store, longer for complex custom applications
- Testing approach
- Gray-box testing with limited account access, closer to a real customer or attacker's view
- Scope covered
- Checkout and payment flows, account takeover paths, Shopify apps and custom code, API endpoints
- Report includes
- CVSS-scored findings, reproduction steps, and a prioritized fix list
- Retest included
- A free retest once fixes are implemented, to confirm each vulnerability is actually closed
- Enterprise scope
- Full source-code review for large SaaS platforms is scoped separately, industry rates run $20,000-$60,000+
- Recommended cadence
- At least annually, and after any major checkout, payment, or authentication change
Who it's for
Stores processing real payment data
You handle checkout and payment flows directly, not just through a hosted checkout, and need proof those flows can't be exploited.
Custom app or headless storefronts
You've built custom Shopify apps, a headless frontend, or bespoke checkout logic that off-the-shelf platform security doesn't cover.
Businesses needing compliance evidence
A client contract, PCI DSS assessment, or cyber insurance renewal requires a documented penetration test, not just a vulnerability scan.
Sites that already ran a security audit
Your audit turned up findings and you want us to actively try exploiting them to confirm real-world risk rather than theoretical risk.
Platforms handling logins and personal data
Customer accounts, saved payment methods, or order history create an account-takeover risk you want tested directly.
Not a fit for
If you just want a list of known vulnerabilities without anyone actively trying to exploit them, our Website Security Audit Services page covers that at a lower cost.
If your core worry is losing data to an outage or accidental deletion rather than a targeted attack, that's covered under Website Backup and Disaster Recovery instead.
If you need a full enterprise SaaS engagement with complete source-code review across a large codebase, that's a bigger scope than our standard testing, we can quote that separately.
09Pricing
Transparent Starting Prices for Web Application Penetration Testing
These are starting points in USD. Enterprise-scale source-code review for large SaaS platforms is scoped separately (industry rates run $20,000 to $60,000+). Your final price depends on your platform and scope, and you get a fixed proposal after a free scoping call.

What does web application penetration testing include?
We manually attempt to exploit your application the way a real attacker would, testing authentication and session handling, checkout and payment logic, API endpoints, and any custom Shopify apps or code, then document every successful exploit path with reproduction steps.
How much do penetration testing services cost?
Standard ecommerce penetration testing starts at $2,999. That's well below the $20,000-$60,000+ range industry sources cite for enterprise SaaS engagements with full source-code review, that tier is scoped separately and isn't what most ecommerce stores need.
How long does a pen test take?
A standard WooCommerce or Shopify storefront test typically takes 1-2 weeks of active testing. Larger custom applications with more user roles, API endpoints, and integrations take longer, scoped based on complexity.
How is a pen test different from a vulnerability scan?
A vulnerability scan lists known weaknesses automated tools can detect. A penetration test goes further, our testers actively attempt to exploit those weaknesses and chain them together the way a real attacker would, confirming which risks are actually exploitable versus theoretical.
Do you provide a fix list and retest?
Yes. Every finding comes with a severity score, reproduction steps, and clear remediation guidance, and we retest for free once your team implements the fixes to confirm each issue is actually closed.
Do you test checkout and payment flows?
Yes, checkout and payment logic is one of the highest-priority areas we test, including discount and coupon logic, cart manipulation, and any custom payment integration code, since these are common targets for real attackers.
Do you test Shopify apps and custom code?
Yes. Custom Shopify apps, headless storefronts, and any bespoke backend code get tested directly, this is exactly the kind of custom logic that off-the-shelf platform security scanning misses.
How often should I run a pen test?
We recommend testing at least annually, plus an additional test any time you ship a major change to checkout, payment processing, or authentication, since those changes are the most likely to introduce new exploitable flaws.
