CREST accredited mobile application penetration testing
Mobile application penetration testing service
CodeShield delivers CREST-accredited mobile application penetration testing for iOS and Android across the UK. A mobile app puts your code, and often your data, directly in the hands of your users, and anyone else who wants to take it apart.
Attackers decompile apps, intercept traffic, and probe the APIs behind them, so we test your app the same way, going far beyond automated scans to find the vulnerabilities that actually put your users and data at risk. No false positives, no fluff. Just clear, prioritised findings and practical remediation advice from a dedicated expert who works with you from scoping through to fixing every issue we find.

CREST-accredited mobile application penetration testing you can trust
When it comes to security testing, credentials matter. CodeShield is a CREST accredited penetration testing company, holding one of the most respected accreditations in the industry.
CREST accreditation isn’t a badge you buy. It’s independent proof that our methodologies, technical expertise, data handling, and quality processes have been rigorously assessed against internationally recognised standards. For you, it means the testing of your mobile app is carried out to a benchmark your clients, auditors, and stakeholders already know and trust.
Why CREST accreditation matters for your business:
- Independent assurance: your testing is validated against standards set and monitored by the industry’s leading not-for-profit accreditation body.
- Procurement-ready: many enterprise customers and public sector frameworks require, or strongly prefer, a CREST accredited provider before they’ll engage.
- Compliance confidence: CREST accredited testing supports frameworks like ISO 27001, SOC 2, and PCI DSS, giving auditors the credible evidence they’re looking for.
- Certified people, not just a certified company: our testers hold individual industry certifications from bodies including CREST and Offensive Security, so your project is always in expert hands.
When you choose CodeShield, you’re partnering with a trusted UK security consultancy that combines independent accreditation, technical excellence, and clear guidance to protect your business against real-world threats.
Mobile application penetration testing for app-driven businesses
Mobile application penetration testing matters most to organisations that ship customer-facing apps, especially those handling sensitive data or operating in regulated markets.
If your app handles personal data, processes payments, or connects to systems that matter, mobile application penetration testing should be part of your security programme.
Meet your compliance requirements with confidence
Many organisations first come to us because a customer, auditor, or framework requires independent testing of their mobile app. We make that requirement straightforward to meet, and turn it into genuine security improvement.
Our mobile application penetration testing supports:
You’ll receive a clear, audit-ready report that maps findings to the standard you’re testing against, plus practical remediation advice to close the gaps, not just document them.

What makes our mobile application penetration testing different
Our Values
What’s in your mobile application penetration testing report
The report is where a penetration test earns its value. A test is only as useful as the document that comes out of it, and ours are built to be read and acted on, not filed away. Every engagement ends with a clear, structured report that works for your development team and your senior stakeholders alike.

Not sure which test you need?
Most people searching “pen test” aren’t sure yet, that’s normal. Pick the closest match, or talk it through directly with a tester. We can incorporate multiple testing types for a single project. We often do web app + network testing if a business wants to cover both.
When do you need a mobile application penetration test?
Mobile application penetration testing isn’t a one-off box to tick. It’s something to build into the key moments in your app’s life. You should consider a test when:
- You’re launching a new app or major update: test before it hits the app stores and real users, not after.
- You’re preparing for a compliance audit: ISO 27001, SOC 2, PCI DSS and similar frameworks expect independent testing as part of certification.
- A customer or partner is asking for it: enterprise procurement and due diligence increasingly require evidence of mobile app testing before they’ll sign.
- You’ve made significant code changes: new features, refactors, or third-party SDKs can introduce vulnerabilities that weren’t there before.
- You’ve added or changed APIs: every new endpoint your app talks to is a new part of your attack surface.
- You’ve had a security incident: verify that the gap is closed and check for anything else an attacker may have reached.
- It’s simply been a while: best practice is at least once a year, and before any major release. If you can’t remember your last test, you’re overdue.
Not sure which of these applies to you? A quick scoping conversation will tell you what you need, and just as importantly, what you don’t.
LIVE REPORTING
Stay informed throughout your penetration test with real-time access to findings through our secure client portal.
As vulnerabilities are identified, they’re immediately available for your team to review, giving you complete visibility into the assessment as it progresses. Any High or Critical findings are communicated straight away via your agreed contact channels, ensuring urgent risks are never left waiting until the final report.
Our collaborative approach also allows for interactive re-testing during the engagement. As fixes are implemented, our consultants can validate them in real time, helping to reduce outstanding vulnerabilities before testing is complete.
At the end of the engagement, your portal is updated with the final quality-assured report, providing a comprehensive record of the assessment, findings, remediation guidance, and supporting evidence.

Mobile application penetration test FAQs
No. Wherever possible we test against a non-production environment such as UAT or QA, so there’s no risk to your live service. If that isn’t possible, we take a more cautious approach to post-exploitation testing to protect your users.
Yes. Our support doesn’t end at the report. Once you’ve addressed the findings, we can retest to confirm the fixes are effective, giving you and your stakeholders verified assurance that the risks have been closed.
Web app testing focuses on browser-based applications, while mobile app testing adds device-specific concerns such as insecure local data storage, binary protections, reverse engineering, and platform configuration, alongside testing the APIs and backend the app relies on.
Not necessarily. We can test with no access (black box), partial access (grey box), or full access to source code (white box). Grey and white box testing often uncover more, and we’ll help you choose the right approach during scoping.
Yes. Each platform has its own risks and security model, so we test both with platform-specific expertise. If your app is on one platform or both, we tailor the engagement to match.
The cost depends on scope: the platforms involved, the size and complexity of the app, the number of user roles and APIs, and the depth of testing required. Rather than quote a misleading flat rate, we scope every engagement individually so you only pay for testing that delivers real value. Get in touch for a tailored quote.
