Mobile Application Testing
Mobile apps handle sensitive data, make background API calls and store information locally – requiring dedicated testing beyond standard web techniques.
Overview
Mobile Application Testing Mobile application testing is a dedicated security assessment that focuses on identifying vulnerabilities within Android and iOS apps. These apps often handle sensitive information such as personal data, payment details and login credentials which makes them a common target for attackers. A thorough test examines how your mobile app behaves on the device, communicates with backend systems and stores or processes data. This type of testing helps ensure your app is secure, not only in how it functions but also in how it protects users and integrates with your wider infrastructure.
Why It Matters
Mobile apps are widely used in both personal and business contexts. Users expect a seamless and secure experience but mobile platforms bring unique challenges. Unlike traditional websites, mobile apps can store data locally, make background requests or rely on device-specific features which can introduce additional risk. If left unchecked, flaws in mobile apps can lead to data breaches, unauthorised access or compromised user accounts. These risks not only affect your users but also your brand and compliance obligations. Mobile application testing helps you understand where your app is exposed and how those risks can be removed or reduced before they are discovered by someone with malicious intent.
In Summary
Mobile application testing is essential for any organisation that develops or distributes mobile apps. It ensures your app is not just functional but also secure and trusted by the users who rely on it. Whether you are launching a new app, updating an existing one or integrating mobile features into your business workflow this testing provides the insight and assurance you need to deliver a secure mobile experience.
Why Organisations Choose This Assessment
Protect User Data
Identifies how sensitive data is handled, stored and transmitted to ensure it is protected against unauthorised access or leakage
Secure App Communication
Tests how the app interacts with APIs, backend systems and third party services to ensure secure communication
Ensure Platform Compliance
Validates that the app follows secure development guidelines and best practice for iOS and Android platforms
What the Assessment Involves
Mobile application testing is carried out by analysing the app both statically and dynamically. This includes reviewing the app’s code structure, storage behaviour and how it communicates with external services. The test may also explore whether sensitive data is stored securely on the device, whether permissions are excessive or if the app can be tampered with or reverse engineered. Common areas of focus include authentication session management, input validation, data storage encryption and API usage. Where appropriate the app will be tested in a real or simulated environment to replicate typical use and identify any unexpected behaviour. At the end of the assessment you will receive a full report of the findings including a breakdown of each issue its impact and practical steps your development team can take to resolve them.

Frequently Asked Questions
Do you test both iOS and Android apps?
Yes. We test both iOS and Android mobile applications. Our methodology follows the OWASP Mobile Security Testing Guide (MSTG) and covers platform-specific issues including local data storage, inter-process communication, network traffic inspection and reverse engineering protections.
Do you need access to the source code?
Source code is not required but is helpful where available. We can test mobile applications in black-box mode using only the compiled application, or in grey-box mode with partial access to source code or documentation. Having access to the source code or API documentation generally allows for a more thorough assessment.
What are the most common vulnerabilities found in mobile apps?
Common findings include insecure local data storage such as sensitive information stored in plaintext, weak or missing certificate pinning, hardcoded API keys or credentials, insecure API communication and insufficient authentication controls. These issues can expose user data, allow account takeover or enable API abuse.
Can you test apps before they are released to the app store?
Yes. We can test pre-release builds directly on test devices or emulators. Testing before release is the ideal time to identify and fix issues, as changes can be made before users are affected. We can work with your development team to integrate security testing into your release process.
