Penetration Testing for Derby Teams

East Midlands

Derby has built aero engines for over a century and trains for even longer. Large aerospace and rail manufacturers sit at the centre of a deep supply chain of engineering consultancies, component makers and software firms. The city was chosen as the home of Great British Railways' headquarters, and naval nuclear propulsion work also takes place here.

Selling software into this supply chain means meeting some of the strictest security requirements in UK industry. Primes cascade cyber clauses to their suppliers, rail clients reference sector standards, and some programmes are government work. Many Derby suppliers need a commercial CREST test; some need CHECK. We help you tell the difference.

What Derby Teams Bring Us to Test

Aerospace supply chain

Suppliers to aero engine and airframe manufacturers share technical drawings, quality records and production data through portals. Primes assess those suppliers' cyber controls, and defence-related contracts carry specific cyber requirements.

What we focus onAccess to technical data and drawings, export-controlled document handling, supplier-to-supplier separation, quality and certification record integrity, and authentication on engineering systems that have been made reachable from the internet.

Rail engineering and asset management

Software for fleet maintenance, asset inspection, timetabling and passenger information connects to railway operations. Rail clients expect suppliers to follow sector cyber guidance and to provide testing evidence before deployment.

What we focus onMaintenance work order permissions, contractor versus engineer sign-off roles, asset record integrity, legacy XML and SOAP interfaces, and audit trails that show who approved safety-related changes.

Engineering consultancies and digital tools

Consultancies build calculation tools, data platforms and project portals for major manufacturers and infrastructure owners. Clients require those tools to meet their supplier security policies before staff or data touch them.

What we focus onProject and client separation, shared workspace permissions, file upload and model parsing, single sign-on integration with client identity providers, and leftover access for engineers who have moved projects.

What We Often Find

Derby's engineering software often carries years of history, and our findings here frequently trace back to older interfaces and complex permission models.

Drawings reachable by document ID

Technical documents served by numeric ID without an ownership check let one supplier download another's drawings. For export-controlled or commercially sensitive data, that is a serious contractual and legal problem.

XXE in legacy SOAP services

Older XML web services still used for integrations may process external entities. A crafted request can read files from the server or reach internal systems behind the firewall.

Contractor can approve their own work

Maintenance platforms sometimes enforce sign-off roles only in the interface. A contractor calling the API directly can approve a task that should need an engineer's authorisation.

Gaps in the audit trail

Changes made through the API, or by administrators, are sometimes not logged with enough detail. When a record is questioned, nobody can prove who changed it or when.

What Derby Buyers Ask For

Def Stan 05-138 and Cyber Risk Profiles

Defence suppliers must meet controls set by their contract's Cyber Risk Profile. Commercial pentest evidence supports several of them, but CHECK is required where the contract or system demands it.

CLC/TS 50701 rail cyber security

Rail clients increasingly reference CLC/TS 50701. A pentest of your web application and APIs provides evidence for the security verification your rail customer expects.

NIS Regulations for rail operators

Train and infrastructure operators are operators of essential services. They pass security expectations to suppliers, and a CREST report helps you meet their assurance requests.

Before you book.

Our prime contractor asked for a pentest on a defence programme. Can you do it?

Read the requirement carefully. If it specifies CHECK, involves classified systems, or sits under a government contract that requires CHECK, you need a CHECK company. CyberFortify is not one. If it is a commercial application, such as a supplier portal used on the programme, a CREST test usually satisfies the request.

Our system still uses SOAP interfaces from the early 2000s. Can you test them?

Yes. Older XML and SOAP services are part of your application if they are reachable, and they are often where serious issues hide. Send us the WSDL files or example requests and we include those endpoints in the same test.

Can the report help with our rail client's cyber security case?

It can support it. The report gives dated evidence of independent testing, findings with risk ratings, and confirmation of fixes after the retest. Your rail client's security case will still need your design, risk assessment and operational controls; the pentest is one piece of evidence within it.

Do you have an office in Derby?

No. CyberFortify has no Derby 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.
