01 / WHAT WE TEST

Your app is the
security boundary.

A store can run on Shopify while an app’s backend, database and deployment pipeline sit elsewhere. We assess the parts you operate and the ways they handle merchant access and data.

Commerce app servers and store connections viewed through a blue inspection prism.
01

Installation & identity

Installation and authorization flows, request authentication, token handling, scope changes, uninstall behavior, account recovery and support access. Each entry point needs the right proof of identity.

02

Store & role isolation

Cross-store access to records, exports, files and background jobs. We test whether a valid user or app installation can reach another merchant’s data or perform actions beyond its role.

03

APIs & business logic

Your REST and GraphQL endpoints, object and function authorization, input handling, uploads and server-side URL fetching. Agreed workflows can include billing, discounts, inventory and bulk operations.

04

Webhooks & storefront paths

Webhook authenticity and duplicate handling; app-proxy permissions; extension-to-backend requests; stored content and settings rendered on storefronts. We check the path from incoming data to its effect.

05

Hosting, cloud & WAF

Agreed app-owned hosts, cloud identities, storage exposure, secrets, network boundaries and origin protection. We assess what the WAF enforces and what still needs application-level authorization.

06

Code & release pipeline

Source-assisted review can trace sensitive logic, dependencies, CI/CD permissions, deployment secrets and artifact controls. Repository and cloud access, review depth and sampling are agreed in the proposal.

Explicit ownership. Explicit permission.

Testing covers your app and authorized assets. It does not authorize attacks on Shopify infrastructure, unrelated merchants or third-party providers. We agree test stores, accounts, data, rate limits and exclusions before work starts.

02 / HOW WE FIND MEANINGFUL RISK

Test the action.
Trace the impact.

VAPT combines vulnerability assessment with manual penetration testing. Automated checks help find exposure; targeted testing establishes whether a weakness can cross a real trust boundary.

Store isolation

Can one installation reach another store’s export?

Follow the request through authorization, database queries, asynchronous jobs and file delivery. Verify both permitted access and expected denials using separate test stores.

Storefront integrity

Can an untrusted request change what shoppers see?

Trace settings and stored content from app endpoints to storefront rendering. Check whether a signed request is being mistaken for permission to perform an administrative action.

Infrastructure access

Can an app flaw reach tokens or deployment privileges?

Where authorized, examine how application access connects to secrets, service identities and release systems. Stop at agreed safety limits and document untested steps.

Test selection draws on OWASP WSTG, ASVS, the OWASP API Security Top 10 and Shopify’s app security guidance. The agreed scope determines coverage; these are testing references, not a certification claim.

03 / WHAT YOUR TEAM RECEIVES

Evidence for the decision.
Detail for the fix.

01

Executive summary

Business impact, affected boundaries and the highest-priority risks, with the scope and limitations stated clearly.

02

Verified technical findings

Affected assets, reproduction steps, sanitized evidence, severity rationale and specific remediation guidance.

03

Coverage & remediation plan

What was tested, what could not be tested and why. Prioritized actions help engineering plan the work.

04

Findings walkthrough

A session to review the findings with your team. Any remediation retest, its window and depth are agreed in the proposal.

What determines the quote?

  • App functionality, roles and sensitive workflows
  • API services, versions and operation count
  • Store isolation, extensions and integrations
  • Hosting accounts and infrastructure in scope
  • Source review, access arrangements and retesting

The starting price is for a bounded engagement. It does not include every category above without limit. We identify the included tests, exclusions and any separately priced work in your proposal.

Remediation implementation, recurring monitoring and third-party assurance or certification are separate services.

06 / WORKING TOGETHER

A clear route from scope to findings.

01 / AGREE

Define safe boundaries

We map the app, data flows and priorities. Agree ownership permissions, two test stores where isolation is in scope, roles, testing windows and escalation contacts.

02 / ASSESS

Test and validate

Review the agreed attack surface and exercise relevant failure cases. Validate findings, avoid unnecessary access to real customer data and escalate urgent issues through the agreed channel.

03 / HAND OVER

Make the next steps clear

Deliver the report and walk through remediation priorities. Confirm any limitations and the evidence needed to verify fixes within the agreed retest scope.

Timing depends on scope and access readiness. Your proposal includes the test window and report date; we do not promise the same turnaround for every app.

DEFINE YOUR SCOPE

Scope your Shopify app penetration test.

Start with your app and APIs; add cloud testing if needed. Include your app URLs, merchant roles, test stores and hosting details. Your completed request is sent to you and Atlant Security.

07 / QUESTIONS BEFORE YOU START

Shopify app testing, explained.

What is Shopify App VAPT?

Vulnerability Assessment and Penetration Testing examines the security of a Shopify app and its agreed supporting systems. We combine exposure and configuration review with manual tests of authentication, authorization, store isolation, APIs and business logic. The report distinguishes verified findings from limitations and areas that were not tested.

How much does Shopify app penetration testing cost?

Pricing starts at $7,000 USD for a one-time, scoped engagement. The final quote depends on functionality, roles, APIs, integrations, hosting coverage, source review and retest requirements. We agree the included work and a fixed price before starting; the starting price is not an unlimited full-stack assessment.

Is this for app developers or Shopify merchants?

This service is for teams developing or operating public or custom Shopify apps. A merchant looking to secure store administration, installed apps, Google Workspace or advertising accounts should use our ecommerce cybersecurity service. We can clarify the correct scope before quoting.

Will you test Shopify’s servers or other merchants?

No. The engagement covers your app and explicitly authorized assets. Test stores and accounts must be approved for the work. Shopify infrastructure, other merchants and third-party systems are outside scope unless separate, valid authorization and applicable provider rules permit the activity.

Can the assessment include hosting and source code?

Yes, when included in the agreed scope. Hosting review can cover cloud identities, exposed services, storage, network rules, secrets and origin protection. Source-assisted work can examine sensitive code paths and build or deployment controls. Read-only evidence review and active exploitation are different activities and are identified separately in the proposal.

Do we need two test stores?

Two isolated test stores are useful for testing cross-store access. We also need suitable accounts for the roles in scope, realistic test data and the relevant API documentation. Where access is unavailable, we agree an alternative and record any resulting limitation.

Does a WAF make the test unnecessary?

No. A WAF can filter some malicious requests, but it generally cannot determine which merchant owns a record or which business actions a role should perform. We test with agreed production-like defenses and, where separately authorized, can compare behavior through controlled access to the origin.

Does this include a retest or a security certificate?

Retest scope, timing and pricing are specified in your proposal. You receive an independent assessment report, not Shopify approval, PCI certification or a guarantee that no vulnerabilities exist. Any customer-facing summary or completion statement must accurately describe the work and its limitations.

How do we start, and how long will testing take?

Complete the RFP builder on this page or book an online scoping call. We agree the app, environments, access, test window and report date before work starts. The schedule depends on scope and access readiness rather than a universal turnaround promise.

Is the sample report a real Shopify app assessment?

No. It is an illustrative, combined penetration test report for a fictional organization. It demonstrates reporting depth across web, API, SaaS and other systems; it is not a client case study or the promised scope of the $7,000 starting engagement. We email the download link after you request it with your company email.
