Penetration Testing for Aberdeen Teams

Scotland

Aberdeen built its economy around North Sea oil and gas, and much of that expertise is now moving into offshore wind, hydrogen and carbon capture. Behind the operators sits a large supply chain writing software: asset integrity tools, permit-to-work systems, crew logistics, inspection reporting and emissions data platforms. Most of it now runs as web applications and APIs.

Energy operators treat suppliers as part of their attack surface. Contracts often ask for independent testing, and operators classed as essential services must manage supply chain risk. Energy-transition start-ups face the same scrutiny from utility partners and investors. A CREST report is the evidence those reviews ask for.

What Aberdeen Teams Bring Us to Test

Oil and gas supply chain software

Service companies in Aberdeen supply operators with asset integrity, maintenance and permit-to-work systems. Operators' security teams expect suppliers to show independent testing before those tools are connected to their sites.

What we focus onContractor and operator role separation, approval of work permits, access to asset and inspection records across clients, and SSO integration with operator identity providers. We also check document links shared with site teams.

Offshore logistics and crew management

Helicopter scheduling, crew rotation and offshore training platforms hold personal data, certificates and travel details. They are used by many companies at once, so isolation between clients matters. Operators check these suppliers closely.

What we focus onBooking and manifest APIs, personal and medical certificate data, cross-company record access, export features, and how account deactivation works when contractors leave. We also look at manifest changes made close to departure.

Energy-transition technology

Offshore wind, hydrogen and carbon capture companies building in the region publish monitoring dashboards and data platforms. Utility partners and funders want security evidence before data is shared. Early-stage teams often meet this before they have security staff.

What we focus onTelemetry and monitoring APIs, read versus write access to sensor and setpoint data, partner data sharing, and exposure of operational information through public dashboards. We also review API keys issued to partners and contractors.

What We Often Find

Energy software in Aberdeen is shared by operators, contractors and partners, so most of the serious findings we look for involve who can see or change what.

Contractor sees other operators' assets

A multi-client integrity platform filters assets in the interface but not in the API. A contractor account for one operator can query inspection records and drawings belonging to another.

Leavers keep access

Contractor turnover is high. If the platform does not end sessions or revoke API tokens when an account is disabled, former staff keep access to permits, manifests or site data for weeks.

Write access on monitoring endpoints

A dashboard API meant for reading telemetry also accepts write requests. Even where no physical control is possible, changed readings can corrupt reporting and trigger false alarms.

Inspection uploads stored publicly

Photos and reports uploaded from site are saved to cloud storage with predictable or public links. Detailed images of installations are then available to anyone with the address.

What Aberdeen Buyers Ask For

NIS Regulations supply chain duties

Energy operators designated under the NIS Regulations must manage risk from their suppliers. A CREST report on the software you provide helps them meet that duty and helps you pass their review.

IEC 62443 and OT scope

Operators often reference IEC 62443 for control systems. Our test covers web applications and APIs only. The report states that clearly, so it supports IT-side assurance without being mistaken for an OT assessment.

Operator supplier prequalification

Many energy buyers run supplier prequalification with security questions. A recent CREST pentest and attestation letter answers the independent-testing questions directly.

Before you book.

Can you test software that connects to offshore control systems?

We test the web application and API layer, such as the portal, dashboards and data APIs. We do not test control systems, SCADA or OT networks, and we would never send traffic towards live operational equipment. If your platform has integrations into OT, we agree boundaries in writing before testing starts.

Our platform serves several operators from one system. Will you check client separation?

Yes, that is usually the most important part. We create or use accounts for at least two client organisations and try to read or change each one's data from the other, through the interface and the API. Isolation failures are reported with clear steps to reproduce and fix.

We are moving from oil and gas into hydrogen. Does a new product need a separate test?

If it is a separate application with its own login and data, yes, it is priced as its own application at £2,400. If it is a new module inside your existing platform sharing the same login and API, it can usually be covered in a single test of that platform.

Do you have an office in Aberdeen?

No. CyberFortify has no Aberdeen 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.
