Penetration Testing for Plymouth Teams

South West England

Plymouth's economy is tied to the sea. Devonport is home to a major Royal Navy base and dockyard, the city has a long-established marine science community and a university known for marine and maritime research, and ferries link the port to France and Spain. A growing digital sector builds software for ocean data, vessel operations and the naval supply chain.

That brings two kinds of security pressure. Defence customers push requirements down the supply chain, and maritime operators face rising attention to cyber risk on ships and in ports. We test commercial web applications and APIs to CREST standards, and we are clear when a contract needs a CHECK company instead.

What Plymouth Teams Bring Us to Test

Marine autonomy and ocean data

Plymouth firms build platforms that control uncrewed vessels, manage sensors and deliver ocean data to researchers and offshore operators. A compromised web console could mean lost data, or a vessel taking commands from the wrong user.

What we focus onCommand and mission APIs, operator role separation, telemetry ingestion authentication, data sharing with research partners, map and geofence editing controls, and session security on control dashboards.

Naval and defence supply chain

Engineering and services firms around Devonport supply maintenance, logistics and training. Their portals exchange schedules, technical documents and personnel details, and primes expect suppliers to show their systems are secure.

What we focus onDocument and drawing access, separation of contractor and customer users, personnel data protection, MFA enforcement, file upload handling, and audit logging of who viewed what.

Port, ferry and maritime logistics

Booking, freight and port community systems move passengers, vehicles and cargo through Plymouth. They connect to customs, hauliers and shipping lines, and an outage or data leak affects operations well beyond the app itself.

What we focus onBooking and manifest IDOR, freight declaration data access, haulier and agent account roles, integration API authentication, sailing availability logic, and the handling of passenger personal data.

What We Often Find

Plymouth's maritime and defence software often connects the web to physical operations, and the findings that matter most sit at that join.

Unauthenticated telemetry ingestion

Sensor or vessel data endpoints that accept posts from anyone who knows the URL. Attackers can inject false positions or readings, misleading operators and corrupting datasets other organisations rely on.

Command endpoints missing role checks

Mission or control APIs that verify a login but not whether the user may command that asset. A viewer account intended for a research partner can send instructions.

Manifest and passenger data IDOR

Booking references or manifest IDs that return full records to any authenticated agent. Passenger names, travel document details and vehicle registrations leak across agencies sharing the platform.

Weak contractor offboarding

Supplier portals where contractor accounts stay active after a project ends, often without MFA. In defence supply chains, stale accounts are a common route in and a contract compliance problem.

What Plymouth Buyers Ask For

NIS Regulations for ports

Port and harbour operators above the thresholds are operators of essential services under the NIS Regulations. Suppliers' web systems feed into that risk picture, and an independent pentest supports the evidence they need.

MOD contracts and the CHECK caveat

Defence customers may ask for CREST testing, Cyber Essentials Plus or CHECK. A CREST web test meets many supplier requests. Where CHECK is named, you need a CHECK company. CyberFortify is not one.

Cyber Essentials Plus is not a pentest

Defence suppliers often hold Cyber Essentials Plus. It checks baseline controls, not your application logic. A web application pentest covers the gaps that certification does not look at.

Before you book.

Our vessel control console is web-based. Can you test it safely?

Yes, with planning. We test command and control functions against a simulator or test asset, never a vessel at sea. Read-only and access control checks can run against production if you prefer. We agree which actions are off limits before testing starts.

Can you test our ferry or freight booking system without disrupting sailings?

Yes. We agree test windows away from peak departures, use test bookings that can be cancelled, and avoid load testing in production. Availability and payment logic is best tested in staging. If anything unexpected affects live bookings, we stop and contact you straight away.

Our research partners reach our ocean data through an API. Do they need to be involved?

Not for the test itself. We use test accounts that mirror partner roles to check what each can reach. If partners host their own systems that connect to yours, we only test your side of the connection unless they give written permission.

Do you have an office in Plymouth?

No. CyberFortify has no Plymouth 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.
