Mobile Security Testing
Find vulnerabilities before attackers find them in your app
What this service delivers
Mobile apps handle sensitive biometrics, financial data, and health records with unique attack surfaces. Our OWASP Mobile Top 10 assessments, API security testing, certificate pinning validation, and data storage reviews identify vulnerabilities that standard web pentests miss, protecting your users and your compliance posture.
- OWASP Mobile Top 10 assessment with severity ratings
- API security testing: authentication, authorisation, and injection
- Certificate pinning and MITM resistance validation
- Sensitive data storage audit: keychain, shared preferences, SQLite
- Jailbreak/root detection and tampering resistance checks
Our approach
How we deliver mobile security testing
A structured, evidence-based methodology that produces findings your team can act on, not reports that sit in a folder.
Static analysis and binary review
We decompile and analyse your app binary using MobSF and manual review to identify hardcoded credentials, insecure configurations, exposed API endpoints in compiled code, and third-party SDK vulnerabilities. For iOS, we review the Info.plist, entitlements, and encryption declarations. For Android, we review the manifest, ProGuard configuration, and exported components.
Dynamic analysis and traffic interception
Using Burp Suite with a custom mobile proxy configuration, we intercept, inspect, and manipulate all network traffic between the app and its backend. We test authentication token handling, session fixation, API authorisation boundaries, injection vectors in requests, and the app's behaviour when certificates are untrusted, validating that pinning cannot be bypassed with standard proxy tooling.
Data storage and runtime security review
We audit all on-device data storage: iOS Keychain and file system, Android Shared Preferences, SQLite databases, and external storage. Using Frida for runtime instrumentation, we verify that sensitive data like tokens, PII, and payment details is not written to insecure storage and cannot be extracted by a malicious app on the same device.
Vulnerability reporting and remediation support
Every finding is assigned a CVSS score, OWASP Mobile Top 10 category, and severity classification (Critical/High/Medium/Low/Informational). We provide specific remediation guidance and a 30-day remediation support window to assist developers in correctly fixing complex vulnerabilities like authentication flows and certificate validation logic.
What you receive
Every engagement delivers a defined set of artefacts. No ambiguity about what you're buying.

Tools & technologies
We use the tools your team already knows where possible, and introduce specialist tooling where it provides accuracy or coverage advantages you can't get otherwise.

Mobile Security Testing, questions your team asks first
Mobile security testing identifies vulnerabilities in an app's code, data storage, network communication, and authentication mechanisms that could allow attackers to steal data, bypass access controls, or tamper with the application.
The OWASP Mobile Top 10 is the industry-standard list of the most critical mobile application security risks, including improper credential usage, inadequate supply chain security, insecure authentication, and insufficient input/output validation.
Yes. Mobile apps are only as secure as their backend APIs. We test authentication tokens, authorisation boundaries, rate limiting, and injection vulnerabilities in the APIs the mobile app consumes.
Certificate pinning restricts the app to trusting only specific certificates, preventing man-in-the-middle attacks. We validate that pinning is correctly implemented for all sensitive API endpoints and cannot be bypassed by standard proxy tools.
