Penetration Testing for Exeter Teams

South West England

Exeter's tech economy has a distinctive centre of gravity: the Met Office, whose headquarters brought weather and climate science expertise to the city. Around it sit the University of Exeter, with its environmental and medical research, and Exeter Science Park, home to data, environmental and health companies. A lot of the software built here delivers data to other systems through APIs.

When the main product is data, the API is the product, and it needs testing as carefully as any user interface. Exeter teams often sell to government, the NHS and corporate risk departments, all of which run formal supplier assessments. An independent CREST test answers those reviews and checks how data is licensed, metered and protected.

What Exeter Teams Bring Us to Test

Climate, weather and environmental data

Companies in Exeter turn climate and environmental data into forecasts, risk scores and dashboards for insurers, utilities and planners. Customers pay for access, so weak API controls give away the product and expose customer locations and assets.

What we focus onAPI key scoping and rotation, rate limiting and metering bypass, licence tier enforcement, bulk download controls, isolation of customer asset and location data, and injection through geospatial query parameters.

Digital health and clinical research

Health tech teams linked to Exeter's medical school and local NHS trusts build tools for remote monitoring, research and patient engagement. NHS buyers will not deploy without assurance, and penetration testing is part of what they ask for.

What we focus onPatient and clinician role separation, IDOR on observations and records, consent management, research data pseudonymisation, FHIR or HL7 integration endpoints, and session handling on shared clinical devices.

GovTech and public sector data services

Exeter firms supply digital services and data products to central and local government. Public buyers follow formal assurance processes, and listing on government frameworks brings questions about how services are tested.

What we focus onCitizen account security, case and record access by staff role, document upload handling, caseworker and admin privilege boundaries, notification template injection, and open data APIs.

What We Often Find

On data-heavy products like those built in Exeter, most serious findings sit in the API layer, out of sight of the interface.

Licence tier bypass

Premium datasets or higher resolutions blocked in the dashboard but returned to any valid key that requests them directly. Customers on a basic plan receive the full product, and revenue leaks unnoticed.

Metering that trusts the client

Usage counted from a header or parameter the caller controls, or not counted at all on batch endpoints. Heavy users avoid limits and costs, and a single key can be used to scrape the whole service.

Geospatial query injection

Location filters, bounding boxes or spatial queries passed into the database without proper parameterisation. These endpoints are often hand-built, and injection here can expose every customer's stored sites.

Patient record IDOR

Observation and record endpoints keyed by sequential IDs, with no check that the requester is the patient or an assigned clinician. Health data for other patients is one request away.

What Exeter Buyers Ask For

NHS DTAC

The Digital Technology Assessment Criteria cover technical security, including penetration testing. A current CREST report answers that section and helps NHS buyers complete their assessment of your product.

G-Cloud and government frameworks

Government buyers on G-Cloud and similar frameworks expect suppliers to explain how services are security tested. A dated CREST report gives you a concrete answer and evidence for buyer assurance questions.

Enterprise data customer due diligence

Insurers, utilities and banks buying climate or risk data run vendor assessments before integration. Independent API testing shows their security teams the service will not become a route into their systems.

Before you book.

Our API serves large gridded datasets. Will testing affect performance for customers?

We design tests to avoid that. Heavy endpoints are tested with small requests first, and any rate limit or resource exhaustion checks are agreed in advance and run against staging where possible. We warn you before any test that could create noticeable load, and stop if your monitoring shows impact.

We are preparing for NHS DTAC. Do you also test the clinician mobile app?

The £2,400 covers the web application and its API, which is usually where DTAC reviewers focus first because patient data lives there. Native mobile apps are scoped separately. If your mobile app calls the same API, testing that API already covers much of the risk.

Do you test open data endpoints that are meant to be public?

Yes. Public does not mean unprotected. We check that open endpoints cannot be abused for injection or denial of service, that they do not return fields meant to be private, and that public and authenticated APIs do not share keys or logic in unsafe ways.

Do you have an office in Exeter?

No. CyberFortify has no Exeter 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.
