Penetration Testing for Gloucester Teams

South West England

Gloucester sits at the heart of Gloucestershire's cyber security cluster, a short drive from GCHQ in Cheltenham, and the county has produced a steady stream of security start-ups. The city is also an established insurance centre, including specialist insurers serving charities and faith organisations, which brings policy administration, claims and broker software with it.

Buyers here often know what a good test looks like and read the report closely. Insurers answer to the FCA on operational resilience, start-ups need credible evidence for their first enterprise deals, and charities face donors and trustees who expect careful data handling. Each needs findings that are validated by an engineer, not raw scanner output.

What Gloucester Teams Bring Us to Test

Insurance and broker platforms

Insurers and brokers in Gloucester run quote engines, policy portals and claims systems connected to aggregators and third-party administrators. These often support important business services under FCA rules, and their suppliers are reviewed accordingly.

What we focus onQuote and premium tampering, policyholder IDOR across documents and claims, broker hierarchy and delegated authority roles, aggregator API authentication, claims file uploads, and payment refund logic.

Cyber security start-ups

Gloucestershire's security founders build threat intelligence, monitoring and compliance products. Their customers expect them to be more secure than average, and a third-party test is usually one of the first things an enterprise buyer requests.

What we focus onTenant separation for customer telemetry, agent registration and enrolment APIs, ingestion endpoints that parse untrusted data, admin console role design, and secrets handling for connected customer environments.

Charity and membership platforms

Charities, churches and membership bodies use donor, Gift Aid and booking systems that hold personal, financial and sometimes special category data. Trustees and insurers expect reasonable security steps, and small charities often run platforms nobody has tested.

What we focus onDonor record access, Gift Aid declaration data, recurring payment management, separation of volunteer and safeguarding data, bulk email and export functions, and public donation forms open to card testing.

What We Often Find

In Gloucester's insurance and security software, the most serious findings usually sit in business logic that automated tools cannot reason about.

Premium recalculation bypass

Quote journeys where risk answers can be changed after the price is fixed, or where the bind request accepts a premium value from the client. The policy issues at a price the underwriting rules never approved.

Delegated authority escalation

Broker portals with sub-broker and principal roles where the API checks the login but not the hierarchy. A junior broker can view or amend policies belonging to another firm in the same network.

Untrusted ingestion parsing

Security products that parse logs, files or alerts sent from customer environments. Weak parsing opens injection or deserialisation paths, turning the monitoring platform into the way in.

Donation form card testing

Public donation pages without rate limiting or bot controls. Criminals use them to test stolen cards in small amounts, leading to chargebacks, payment provider penalties and a frozen merchant account.

What Gloucester Buyers Ask For

FCA operational resilience

Insurers must identify important business services and show they can stay within impact tolerances. Independent penetration testing of customer-facing systems provides evidence for the cyber side of that self-assessment.

CHECK and government-facing work

Some Gloucestershire firms bid for government contracts that name CHECK. CyberFortify is not a CHECK company, so that work needs a CHECK provider. For commercial buyers, a CREST test is the normal standard.

Charity Commission and trustee duties

Trustees are expected to manage risks to charity data and finances. A dated pentest report gives a board clear evidence that the donor platform was tested and that issues were fixed.

Before you book.

Our insurer clients map supplier findings into their own third-party risk framework. Will the report fit?

Yes. Each finding includes a severity rating, affected endpoints, reproduction steps and remediation advice, which most third-party risk teams can map to their own scoring. After the retest, the report shows which findings are closed. If a client uses a specific questionnaire, send it over and we will point you to the relevant sections.

We are a security start-up preparing for our first enterprise deal. When should we test?

Before the buyer's security review starts, not during it. Enterprise buyers usually want a recent report with critical and high findings fixed. Testing a few weeks ahead leaves time to remediate and use the included retest, so you hand over a clean report rather than an open list.

Can you test our donation platform without processing real card payments?

Yes. We use your payment provider's test mode or sandbox wherever possible. On live donation forms we check rate limiting and bot controls with a small number of agreed requests, and we never submit real card numbers. Card handling itself stays with your provider, so we focus on what your platform controls.

Do you have an office in Gloucester?

No. CyberFortify has no Gloucester 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.
