Penetration Testing for Portsmouth Teams

South East England

Portsmouth has been a naval city for centuries and is home to a major Royal Navy base. Its economy still leans on defence, shipbuilding support, marine engineering and the many small firms that supply them. Around the harbour and the Solent there is also a large leisure marine industry. Software here tends to manage assets, maintenance, engineering data and supply chains for demanding customers.

Defence primes push security requirements down to every tier of supplier, including small software firms. That means questionnaires, cyber risk profiles and, increasingly, evidence of independent testing. Be clear on one point first: some government and critical national infrastructure contracts require a CHECK company. CyberFortify is not one. If your contract names CHECK, we will tell you before you book.

What Portsmouth Teams Bring Us to Test

Defence supply chain software

Small and mid-size suppliers to defence primes run engineering portals, document management and logistics tools. Primes assess them against the MOD's cyber requirements, and a web application test is often requested for systems handling contract data.

What we focus onAccess controls on technical drawings and contract documents, project-level separation, export functions, user offboarding, and file handling where engineering data is uploaded or shared between companies.

Marine engineering and leisure marine

Boatbuilders, refit yards and marine equipment makers around the Solent use customer portals, parts ordering and warranty systems. They hold owner details and commercially sensitive build specifications that competitors and fraudsters would value.

What we focus onOwner and vessel record IDOR, warranty and parts ordering logic, dealer network roles, price and discount manipulation, and access to build specifications and service history through the API.

Asset and maintenance management

Planned maintenance and asset tracking platforms are used for ships, port equipment and engineering plant. If records can be altered, safety and certification are affected, so operators want assurance the web layer is sound.

What we focus onWho can sign off work orders, tamper resistance of inspection records, audit history, technician mobile APIs, and whether a contractor account can see assets belonging to other clients.

What We Often Find

For the engineering and defence-adjacent platforms common in Portsmouth, these findings are the ones that most concern customers.

Documents reachable by direct link

Drawings, specifications or contract files are stored with predictable URLs and served without checking the requester. Anyone who obtains or guesses a link can download controlled material.

Editable maintenance history

A technician can change the date, result or signatory of a completed inspection through the API. That undermines certification and can hide unsafe equipment from auditors.

Leavers keep access

Accounts for contractors and former staff stay active, or API tokens issued to them keep working after the user is disabled. Primes often ask about this directly in supplier reviews.

Dealer roles that see too much

A dealer or service agent can query owner records, pricing and build details for vessels outside their territory. Commercial data leaks quietly and is hard to detect afterwards.

What Portsmouth Buyers Ask For

Def Stan 05-138 and the Cyber Security Model

MOD contracts assign a cyber risk profile that suppliers must meet. Independent application testing provides evidence for the controls around secure systems and vulnerability management in your assessment.

JOSCAR

Many aerospace and defence buyers use JOSCAR to collect supplier information. A recent pentest report helps you answer security questions consistently across several primes.

CHECK requirements

Where a contract or system owner specifies CHECK, only an NCSC CHECK company can do the work. We are not one. We will say so plainly rather than sell you a test that will not be accepted.

Before you book.

Our prime contractor wants a pentest. How do we know whether it must be CHECK?

Check the contract, the security aspects letter or ask the prime's security team directly. CHECK is normally required for government systems and some critical infrastructure, not for every supplier application. If they accept a CREST test, we can help. If they say CHECK, use a CHECK company and we will happily point you in that direction.

Can you test a system that holds OFFICIAL-SENSITIVE data?

That depends on the customer's rules for who may access the system and its data. Some primes require testers with specific clearances. Tell us the classification and any conditions before booking and we will confirm whether we can meet them. If we cannot, we will say so rather than work around it.

We are a small marine firm with a dealer portal. Is a pentest overkill?

Not if the portal holds owner data, pricing or build specifications for many dealers. A single test at a fixed price shows whether dealers can see each other's data and whether ordering logic can be abused. It also gives you a clear answer when a larger customer asks about security.

Do you have an office in Portsmouth?

No. CyberFortify has no Portsmouth 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.
