Mobile Application Penetration Testing
Senior-led testing of your iOS and Android apps, aligned to OWASP MASVS. We manually exploit the insecure storage, weak crypto, authentication and API flaws that automated scanners and app-store reviews miss — across the client, the data in transit and the server-side — then hand you a prioritised, evidence-backed report and a free retest to prove every fix holds.
- OWASP MASVS & MASTG aligned
- iOS & Android — real-device testing
- OSCE / OSCP-certified testers
- Free remediation retest included
Your app ships the keys to your backend in every user's pocket.
A mobile app is a client you don't control — attackers decompile it, read what it stores on the device, tamper with it at runtime, and hit the APIs behind it directly. An app-store review and an automated scan won't catch insecure storage, a bypassed jailbreak check, or broken object-level authorisation. A senior tester does exactly what an attacker would, on both platforms, before they do.
Full OWASP MASVS coverage — client, network and server-side.
Structured around the OWASP MASVS and MASTG, then extended with the manual, business-logic testing that separates a real assessment from an automated scan.
-
Insecure Data Storage
Sensitive data in the keychain / keystore, databases, caches, logs and backups on the device.
-
Authentication & Session
Login, biometric and MFA bypass, session handling and token weaknesses.
-
Cryptography
Weak or misused crypto, hardcoded keys and insecure random number generation.
-
Network Communication
TLS configuration, certificate-pinning bypass and traffic interception.
-
Platform Interaction
Insecure IPC, deep links, WebViews, exported components and over-broad permissions.
-
Reverse Engineering & Tamper
Decompilation, runtime instrumentation, jailbreak / root and anti-tamper resilience.
-
API & Backend
The APIs behind the app — BOLA, mass assignment, excessive data exposure and rate-limit gaps.
-
Code Quality
Injection, memory issues and unsafe use of platform APIs.
From scope to retest — a disciplined, four-phase engagement.
-
01
Scope & rules of engagement
We agree the iOS / Android builds, test accounts, backend environments and constraints, and set safe testing windows.
-
02
Static & dynamic analysis
We decompile and inspect the app, map its on-device storage and the APIs behind it, and instrument it at runtime on real devices.
-
03
Manual exploitation
We hand-test and safely exploit each class of flaw across both platforms, chaining issues to prove real, business-relevant impact.
-
04
Report & free retest
You get a prioritised, evidence-backed report; after you remediate, we retest to confirm every fix — at no extra cost.
A report your engineers can act on — and your auditors accept.
-
Prioritised findings
Every issue risk-rated by real business impact and ordered so you fix what matters first.
-
Reproducible evidence
Step-by-step proof-of-concept per finding, per platform — no vague, unverifiable claims.
-
Developer-ready remediation
Specific, actionable fix guidance for your iOS and Android engineers, not a generic checklist.
-
Executive summary
A plain-language overview for leadership, boards and clients requesting assurance.
-
Free remediation retest
We re-test your fixes and confirm they hold — included with every engagement.
-
Attestation letter
A summary letter you can share with customers, partners and app-store / enterprise reviewers on request.
Evidence that maps to the frameworks you report against.
One engagement, structured so its output slots straight into the assurance work you already have to do.
| Framework | How this engagement maps |
|---|---|
| OWASP MASVS & MASTG | Testing is structured directly around the OWASP Mobile AppSec Verification Standard and Testing Guide. |
| PCI-DSS | Satisfies application penetration-testing requirements where the app handles cardholder data. |
| SOC 2 | Provides the independent pentest evidence auditors expect for the Security trust-services criteria. |
| ISO 27001 (A.8.29) | Supports the secure-development and technical-review controls in your ISMS. |
| App Store / Enterprise review | Evidence of a formal security assessment for app-store, MDM and enterprise-distribution requirements. |
What teams ask before a mobile app test.
What's the difference between a mobile pen test and an app-store review or scan?
An app-store review checks policy compliance and an automated scan flags known patterns; a penetration test is a senior human decompiling, instrumenting and exploiting the app and its APIs on real devices. We never scan-and-send.
Do you test both iOS and Android?
Yes — we test both platforms as standard, since the storage, crypto and platform-interaction flaws differ between them. We can scope a single platform if you only ship one.
Do you need our source code?
No. We test the compiled app as an attacker sees it (black / grey-box). Source or a test build speeds up coverage, but it isn't required.
Do you test the APIs behind the app?
Yes. The backend APIs are where most real impact lives — we test them directly for authorisation, data-exposure and logic flaws as part of the engagement.
How long does a mobile app penetration test take?
Most engagements run one to two weeks depending on the app's size, platforms and backend complexity. We confirm timing at scoping.
Can we use the report for SOC 2, PCI-DSS or an app-store / enterprise review?
Yes. The report and optional attestation letter are written to satisfy auditor, customer and app-store / enterprise requirements.
