Penetration Testing for Winchester Teams

South East England

Winchester is Hampshire's county town and the seat of Hampshire County Council, which shapes much of its economy. Around the council sit legal practices, accountants, financial planners and the consultancies and software firms that serve the public sector. The city is also home to the University of Winchester. Software here is often built for case work, client records and regulated advice rather than consumer markets.

Councils assess suppliers formally, often starting with Cyber Essentials and moving on to application testing for systems that hold resident data. Law firms and advisers face pressure from insurers and regulators to protect client money and confidential files. In both cases, a current independent pentest is now a standard request rather than an exception.

What Winchester Teams Bring Us to Test

Software for local government

Case management, licensing, social care and housing platforms hold sensitive resident data. Councils buy through frameworks and their own assessments, and expect suppliers to show testing beyond a Cyber Essentials certificate.

What we focus onCaseworker versus manager roles, access to safeguarding and social care records, citizen-facing forms and uploads, payment of fees, and integrations with other council systems through shared APIs.

Legal practices and legal tech

Client portals, conveyancing tools and document exchange platforms are targeted by fraudsters who want to redirect completion funds. Insurers and clients now ask firms and their software providers what testing has been done.

What we focus onChanges to bank details and payment instructions, document access between matters, client portal authentication, notification emails that can be spoofed or triggered, and fee-earner permissions.

Financial planning and advice

Advisers and the platforms they use hold pensions, investment and identity data. Client-facing portals are a natural target, and the firms using them are FCA regulated and expected to manage cyber risk.

What we focus onClient and adviser separation, document vaults containing identity and pension statements, fact-find forms, account recovery, and whether one adviser's clients are visible to another firm on a shared platform.

What We Often Find

In the resident, client and matter-based systems that Winchester suppliers build, these findings come up repeatedly.

Bank detail changes without verification

A client or compromised account can change payout details through the portal with no second check or alert. This is the core of conveyancing and payment diversion fraud.

Safeguarding records too widely visible

Sensitive case notes are protected in the interface but returned by an API to any caseworker. Councils treat exposure of safeguarding data as a serious incident.

Matter documents shared by link

Documents uploaded to a client portal are served from guessable or permanent links. Confidential legal or financial files can then be reached without logging in.

Weak account recovery

Recovery flows rely on information that is easy to find, such as date of birth and postcode. For elderly or vulnerable clients this makes account takeover far too simple.

What Winchester Buyers Ask For

Cyber Essentials Plus is not a pentest

Councils often ask for Cyber Essentials Plus first. It checks basic controls on your devices and network, not your application. A pentest covers the platform residents actually use, and buyers increasingly ask for both.

G-Cloud and public sector frameworks

Suppliers listing on government frameworks are asked about security testing. A CREST report gives you a clear answer. Where a buyer specifies CHECK, we will tell you, as we are not a CHECK company.

UK GDPR processor duties

As a processor for councils or law firms, you must apply appropriate security under Article 28 contracts. A dated pentest with retest results is practical evidence your controllers can rely on.

Before you book.

We sell the same platform to several councils. Can one report serve all of them?

Usually, yes, if every council uses the same version of the same application. We test it once and issue a report plus an attestation letter you can share with each buyer. If some councils run customised modules or separate hosting, tell us at scoping, since those differences may need to be covered too.

We supply conveyancing software. What should a test focus on?

Payment diversion first. We look at every way bank details or completion instructions can be changed, who can change them, and whether clients and fee earners are alerted. We also test matter separation and document access, since one leaked file can reveal the timing of a completion.

Can you test a system that holds children's social care records?

Yes, normally against a staging environment with synthetic data, which is what most councils prefer. We will confirm any conditions the council sets, such as data handling or tester location, before booking. If the council requires a CHECK company for that system, we will say so.

Do you have an office in Winchester?

No. CyberFortify has no Winchester 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.
