Penetration Testing for York Teams

North Yorkshire

Rail has shaped York for nearly two centuries, and the city still hosts a major Network Rail operating centre and a cluster of rail engineering and software firms. Insurance and financial services are long-established employers. To the east, the York Biotech Campus at Sand Hutton supports agri-food and plant science research. Software made here plans train services, prices policies and records lab results.

Rail operators fall under the NIS Regulations and ask suppliers hard questions. Insurers run detailed vendor due diligence before connecting a new platform. Science teams share data with government and commercial partners who want it protected. A CREST pentest gives each of them independent evidence instead of a self-assessment.

What York Teams Bring Us to Test

Rail technology

York's rail software firms build planning, asset, maintenance and passenger information tools for operators and infrastructure owners. Those customers must manage supplier risk under the NIS Regulations, so testing evidence is often a contract condition.

What we focus onAccess separation between operators and contractors, integrity of timetable and asset data APIs, passenger information feeds, partner authentication and admin interfaces. Signalling and operational systems are out of scope.

Insurance and policy administration

Quote engines, broker portals and claims tools serving York's insurance community hold personal and financial data. Insurers run vendor due diligence on any platform touching policyholders, and they ask for independent testing.

What we focus onQuote and premium tampering, broker and policyholder role separation, claims document access, payment and refund flows, and fraud-prone changes such as address or payee updates during a claim.

Agri-food and plant science

Laboratory, sample tracking and research data systems linked to York's agri-food science base hold commercially sensitive results and publicly funded data. Partners and funders expect access to be tightly controlled.

What we focus onSample and result access between clients and projects, web front ends for lab systems, result report downloads, instrument upload endpoints, and user management for external partners.

What We Often Find

Across York's rail, insurance and science platforms, these are the weaknesses that most often change the outcome of a vendor review.

Premium tampering

Quote APIs that accept risk factors or discounts from the browser without server-side checks let a user lower their own premium. Brokers and comparison journeys can expose this at scale.

Contractor access to asset data

Rail asset and maintenance tools sometimes let contractors view assets outside their contract area by changing a filter. That spreads infrastructure detail far wider than intended.

Lab results by sequential ID

Result reports with incrementing IDs can be downloaded by any logged-in client simply by changing the number. For commercial testing labs this leaks confidential results to competitors.

Claims payee change without checks

Claims flows that let the payee or bank account change late in the process, without verification, are a known fraud route. We test how the change is authorised and logged.

What York Buyers Ask For

NIS Regulations (transport)

Rail operators and infrastructure managers must manage risk from their suppliers. An independent pentest of your web platform helps them, and you, show that supplier risk is being handled.

Insurer vendor due diligence

Insurers' third-party risk teams ask for recent testing by an accredited firm and proof of remediation. Our CREST report and retest letter answer both questions directly.

UK GDPR and research data agreements

Data sharing agreements with funders and partners usually require appropriate security measures. A dated pentest report is concrete evidence that those measures exist and work.

Before you book.

Our rail customer asked about NIS. Does your pentest make us compliant?

No single test makes anyone compliant. The NIS duties sit with the operator, who must manage risk from suppliers like you. A CREST pentest of your web platform, with fixes retested, is strong evidence for their supplier assessment. We test commercial web apps and APIs, not signalling or operational systems, and we will say if your contract needs something else.

Can you test our quote engine without creating real policies?

Yes. We test in a staging or UAT environment where possible, with test brokers and policyholders set up for us. If production must be tested, we agree rules to avoid binding real cover or triggering payments. Flaws in premium calculation can usually be proven without completing a purchase.

Our lab system serves commercial clients and public bodies. What do you focus on?

Client separation comes first. We check that no client can see another's samples, results or invoices through the interface or the API. Then we look at report downloads, instrument upload endpoints, partner accounts and admin functions. For a lab, a leaked result can matter as much as leaked personal data.

Do you have an office in York?

No. CyberFortify has no York 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.
