Mobile App Penetration Testing Providers
Mobile application penetration testing assesses the security of iOS and Android applications by examining the app binary, its communication with backend APIs, local data storage, authentication mechanisms, and platform-specific security controls. Testers analyse the application for vulnerabilities including insecure data storage, weak cryptography, improper session handling, client-side injection, and reverse engineering risks.
Testing follows frameworks such as the OWASP Mobile Application Security Verification Standard (MASVS) and Mobile Testing Guide (MSTG). Mobile pen testers examine how the app handles sensitive data at rest and in transit, whether certificate pinning is properly implemented, how the app responds to jailbroken or rooted devices, and whether binary protections prevent reverse engineering and tampering.
This testing is essential for organisations releasing mobile apps that handle financial transactions, personal data, healthcare information, or corporate credentials. Mobile app pen testing helps meet compliance requirements for PCI DSS, HIPAA, GDPR, and industry-specific regulations.

Mobile App Penetration Testing FAQs
Do you test both iOS and Android?+
Most penetration testing providers test both platforms. Some specialise in one platform. Ensure your chosen provider has experience with the specific platform and version your app targets.
Do you need access to source code for mobile app testing?+
Mobile app pen testing can be performed with or without source code. Black-box testing analyses the compiled binary, while white-box testing with source code access typically finds more vulnerabilities.
How long does mobile app pen testing take?+
A typical mobile app pen test takes 5-10 days per platform, depending on app complexity, number of features, and whether backend API testing is included.
