Penetration Testing for Doncaster Teams

South Yorkshire

Doncaster sits where the A1(M), M18 and the East Coast Main Line meet, which is why so much of its economy moves goods. Large distribution parks, inland rail freight and a long railway engineering history shape the software built and bought here: warehouse systems, carrier integrations, fleet portals and the shift tools that staff big sheds around the clock.

Logistics customers now send security questionnaires before they connect a new system to their stock or order data. Rail clients ask suppliers to show how their portals are secured. A CREST report written for those reviewers answers the question once, with evidence, instead of another self-assessed spreadsheet.

What Doncaster Teams Bring Us to Test

Warehousing and fulfilment

Fulfilment platforms here plug into retailers, marketplaces and carriers through dozens of APIs. A client will usually want proof that one shipper's orders, stock levels and customer addresses cannot be seen or changed by another before they sign.

What we focus onShipper-to-shipper isolation, consignment and order IDs that can be guessed, carrier label endpoints, bulk CSV imports, webhook signing and the admin roles that warehouse supervisors use to override picks.

Rail engineering and maintenance

Doncaster's rail heritage means plenty of firms run asset, inspection and maintenance software for the wider rail industry. Those buyers take supplier security seriously because their portals sit close to safety records and engineering data.

What we focus onAccess to inspection records and defect reports, contractor accounts that outlive the contract, file uploads for drawings and photos, audit trails that can be edited, and exports from asset registers.

Temporary staffing and shift booking

Big distribution sites lean on agency and shift-booking apps to fill rotas. Those apps hold right-to-work documents, bank details and home addresses for thousands of workers, so clients and agencies both ask how that data is protected.

What we focus onWorker profile IDOR, document storage links, shift-swap and timesheet approval logic, pay rate tampering, role escalation from worker to site manager, and password reset flows on mobile-first web apps.

What We Often Find

Logistics and rail software in Doncaster tends to fail where many partners share one platform. These are the issues we see most in that kind of app.

Guessable consignment references

Tracking pages and APIs that accept sequential consignment numbers without checking the caller. Anyone can walk the range and collect names, addresses and delivery notes for every shipper on the platform.

Carrier API keys in the browser

Keys for courier or label APIs shipped in front-end JavaScript. An attacker can print labels, cancel jobs or read shipment data against your account, and the bill lands with you.

Timesheet approval bypass

Approval endpoints that trust a role sent by the client. A worker can approve their own hours or change a pay rate by editing one field in the request.

Unthrottled bulk export

Report and export endpoints with no rate limit or size cap. One compromised supervisor login can pull the full order or worker history in minutes without raising an alert.

What Doncaster Buyers Ask For

Retailer and 3PL security questionnaires

Large shippers ask fulfilment partners for recent independent testing before integration. The report gives scope, findings and retest results you can attach rather than describe.

Rail supplier assurance

Rail clients often ask for evidence of security testing during supplier onboarding and renewals. A CREST report with retest confirmation shows your portal has been checked by an accredited tester.

UK GDPR for worker data

Right-to-work scans, bank details and addresses are high-risk personal data. Testing the app that stores them supports your Article 32 security duty and any DPIA you keep.

Before you book.

Our warehouse system has separate portals for shippers, drivers and site staff. Is that one app?

Usually yes, if they share one codebase and API and differ only by role. We test each role against the others, which is where most logistics flaws hide. If the driver tool is a native mobile app, that part is scoped separately. Send us the URLs and we will confirm before you commit.

Can you test our carrier and marketplace integrations without breaking live shipments?

We test against a staging or sandbox environment where possible and agree rules for anything that must touch production, such as no label creation against live carrier accounts. We check how your API handles webhooks and keys from partners, not the partners' own systems, which we are not authorised to test.

Do you test the warehouse scanners and site network too?

No. The £2,400 covers your web application and its API. Handheld scanner apps, Wi-Fi and the internal network on a distribution site are separate pieces of work with their own scope and price. Many Doncaster teams start with the customer-facing portal because that is what clients ask about first.

Do you have an office in Doncaster?

No. CyberFortify has no Doncaster office. Web application and API tests run remotely, which is how almost all application pentests are delivered. Kick-off, critical alerts and the report walkthrough happen in UK working hours, and the price is the same £2,400 flat.

Why is it cheaper than UK day-rate firms?

Our AI Pentest Agent covers the breadth of your app: mapping every page and API route and checking the known issues. That frees our CREST-accredited engineers for exploitation, access control and business logic. Fewer billable days means one flat fee instead of a day rate. Every finding is still validated by a person before it reaches your report.

Is CyberFortify really CREST accredited?

Yes. CyberFortify is a CREST member company, accredited for Penetration Testing and AI-Enabled Penetration Testing, and a signatory of the CREST AI Charter. You can check our listing on the CREST Marketplace before you book.

What counts as one application?

One web product your users sign in to, plus the API behind it. Size doesn’t change the price: a large SaaS platform with many roles is still £2,400. A mobile app, an internal network or a cloud configuration review is a separate scope, and we’ll quote it on the call if you need it.

Is the price really fixed?

Yes. £2,400 per application, agreed on the scoping call before testing starts. The retest of your fixes is included. There are no day rates, so the invoice doesn’t grow if testing takes longer.

Is Cyber Essentials Plus the same as a penetration test?

No. Cyber Essentials Plus is a certification with a hands-on check of five basic controls. It doesn’t test your application for vulnerabilities the way a penetration test does.

Are you a CHECK company?

No. CHECK is the NCSC scheme for UK government and critical national infrastructure systems. If your contract names CHECK, you need a CHECK company, and we’ll tell you so on the call. CyberFortify is CREST accredited.

How fast can you start?

Testing usually starts within a week of the scoping call, and most reports are ready in four to seven working days. Criticals are flagged within 24 hours of discovery.

What happens to our data?

CyberFortify works under ISO 27001 certified processes. Client data from the engagement is disposed of afterwards, as set out in the statement of work. Every assignment carries professional liability insurance and Koop cyber insurance.
