Mobile App Penetration Testing in Cardiff
Mobile app penetration testing for Cardiff organisations, where the application runs on hardware the attacker controls. Anything enforced only in the app — a price check, a permission, a validation rule — can be observed, modified or removed entirely, so the useful question is what happens when the client is assumed hostile.
Why this comes up
The problem
Purchase validation happens in the app and the server accepts whatever the app submits.
What you get
What we deliver
- Server-side enforcement verified for every control the app appears to apply
- Traffic inspected, including whether certificate pinning can be circumvented
- Local storage examined for credentials, tokens and data held unnecessarily
- Binary reviewed for hardcoded secrets, which are recoverable however obfuscated
- Platform protections assessed, including behaviour on rooted or jailbroken devices
- Backend tested alongside the app, since that is where the real controls must live

Wales
Cardiff has a significant broadcast and media sector alongside a large public-sector presence, and Welsh-language provision is a genuine requirement on public-facing work here rather than a nice-to-have.

Mobile App Penetration Testing in Cardiff — common questions
- Why treat the client as hostile?
- Because it is physically in somebody else's hands. The application can be decompiled, instrumented and modified, so every check within it is advisory — the only controls that hold are the ones the server enforces independently of what the app says.
- Are hardcoded secrets really recoverable?
- Essentially always. Obfuscation raises the effort and does not prevent extraction, so an API key or credential compiled into the application should be treated as public — which means the backend must be designed on the assumption that it is.
- Does certificate pinning help?
- It raises the difficulty and does not stop a determined tester. Pinning is worth implementing to deter casual interception, and it should not be relied upon as a security boundary — it can be bypassed on a device the attacker controls.
- Should the backend be in scope?
- It usually should, because that is where exploitation happens. Testing the app in isolation identifies client weaknesses; testing it against the API establishes whether those weaknesses lead anywhere, which is the question that actually matters.
- Do you work with businesses across Cardiff?
- Yes. We are based in Leicester, United Kingdom and work with clients throughout Wales, including Cardiff and the surrounding Cardiff area. Most collaboration happens remotely, and we travel for kick-offs and key milestones.
- What kind of Cardiff businesses do you usually work with?
- Public sector and broadcast work is common, and bilingual provision is usually a requirement rather than an option. Beyond that we work across Media & Broadcasting, Financial Services, Public Sector, Higher Education and Sport.
- Do you cover the areas around Cardiff?
- Yes — we work throughout Wales, including Bristol, Swansea. Cardiff is an urban area of roughly 490,000+, and we take on work across the wider Cardiff region rather than the city boundary alone.
