Mobile application security testing examines how an app protects data and enforces important decisions. ProCheckUp assesses the agreed mobile application together with supporting APIs and business workflows.
Supported apps and backend scope
- iOS or Android applications and the supplied test builds
- Authentication, local storage and platform interactions
- Backend APIs and business logic included in the scope
Mobile Application Testing

In the dynamic realm of mobile applications, ensuring security is paramount. ProCheckUp's Mobile Application Testing Service is tailored to discern potential security gaps in your application. This might arise from vulnerabilities, configuration lapses, or deviations from security best practices. While Web application testing is typically browser-based, mobile application testing delves deeper into compiled applications. Here, a significant portion of the processing and functionality rests within the application itself.
Our rigorous assessment, tailored to the specific technologies and functions of each application, typically encompasses the following key areas:
- Local Data Storage: Examining how data is stored locally on the device.
- Reverse Engineering: Identifying vulnerabilities by deconstructing the application.
- Session Management: Ensuring secure user sessions and authentication processes.
- Data in Transit: Analyzing the security of data as it moves between systems.
- Running Processes: Investigating the application's operational security.
- Application Filesystem: Scrutinizing the app's file storage and access mechanisms.
- Input Validation: Ensuring user inputs do not lead to vulnerabilities.
- Known Vulnerabilities: Checking against databases of documented security threats
Upon concluding the assessment, our clients receive a comprehensive technical report. This documentation offers in-depth insights into identified vulnerabilities, accompanied by strategic remediation recommendations. For a succinct overview, an executive summary elucidates the most critical security concerns.

Preparing for the engagement
Provide the builds, user roles, endpoints and representative transactions to test. Agree any limitations caused by signing, entitlements, certificate pinning or third-party services.
Outcomes and next steps
The report should distinguish application defects from test-environment limitations. Our Apple Pay integration case study illustrates testing across the mobile client and supporting payment API.
ProCheckUp case study
ProCheckUp tested a pre-release iOS Apple Pay integration and its supporting API, including guest and authenticated transaction workflows.
