App Security Testing Service

Mobile applications have become increasingly essential tools for personal information and financial security. Once a security issue occurs, it can lead not only to user data breaches but also to financial losses—and in severe cases, pose significant threats to national information security. Due to the technical complexity of mobile application security, most app developers are unable to fully and quickly understand the security risks and vulnerabilities of their applications. They often lack the expertise to conduct in-depth assessments and analyses of their app’s security status, and are even less equipped to systematically resolve security issues. Meanwhile, professional mobile application security engineers are scarce and costly, making it difficult to meet the growing demand for large-scale security evaluations.

TOPDATA provides comprehensive security testing services covering seven major platforms: Android (including AAB), iOS, HarmonyOS NEXT applications, Android SDK, iOS SDK, HarmonyOS 2.0 applications, and WeChat Official Accounts/Mini Programs. By combining deep static code analysis with dynamic attack validation, our services offer over a hundred security checks, including source code protection, data storage, communication transmission, and security defense.
Based on OWASP Mobile Top 10, national information security standards, and industry testing specifications, our platform supports automated testing with optional manual validation. This ensures assessments are aligned with real-world business scenarios, enabling users to thoroughly evaluate application security, precisely locate vulnerabilities, and receive detailed issue reports along with sample code fixes—resolving problems at their root and effectively securing applications.
We offer both automated tool-based assessments and expert manual evaluations to meet diverse security testing needs, enabling fast, comprehensive app security evaluations.

1. Android Application Security Testing

Android application security testing covers a wide range of areas, including application self-protection, program source file security, local data storage security, communication data transmission security, identity authentication security, internal data interaction security, HTML5-related security, anti-malicious attack capabilities, and optimization suggestions—encompassing over 100 assessment items.

The service supports automated testing of APK and AAB file formats. Through fully automated deep static code analysis and dynamic simulated attack testing, it comprehensively identifies security issues within the Android application and its integrated third-party SDKs. A professional security assessment report is generated, providing constructive remediation suggestions to assist developers in fixing vulnerabilities and improving overall application security.

2. iOS Application Security Testing
iOS application security testing covers various areas, including app self-protection, binary code protection, client-side data storage security, data transmission security, encryption algorithm and password security, source code security, and compliance with iOS security guidelines.

3. HarmonyOS NEXT Application Security Testing
HarmonyOS NEXT application security testing includes eight major categories: application self-protection, source code security, local data storage security, communication data transmission security, anti-malicious attack capabilities, HTML5 security, internal data interaction, and optimization suggestions.

4. HarmonyOS 2.0 Application Security Testing
The security testing scope for HarmonyOS 2.0 applications covers app self-protection, source code security, local data storage security, communication data transmission security, internal data interaction security, anti-malicious attack capabilities, and optimization suggestions.

5. Android SDK Security Testing

• Method 1: SDK Integrated within App
  Submit the Android app with one click to automatically identify third-party SDKs integrated into the app. The system performs static analysis on each SDK to detect security vulnerabilities. If any are found, a detailed report is generated for each SDK, covering areas such as self-protection, local data storage security, internal data interaction, and anti-malicious attack capabilities.
• Method 2: Standalone SDK Testing
  Submit the Android SDK package directly for automated analysis of source code security issues. The resulting report covers aspects such as self-protection, source code security, local data storage security, internal data interaction, and anti-malicious attack capabilities.

6. iOS SDK Security Testing
iOS SDK security testing covers self-protection, binary code protection, client-side data storage security, data transmission security, encryption algorithms and password security, and source code security.

7. WeChat Official Account / Mini Program Security Testing
Security testing for WeChat Official Accounts and Mini Programs includes app self-protection, communication transmission security, data leakage risk detection, component vulnerability scanning, and insecure HTTP configuration checks. Server-side automated scanning technology enables full traversal of mini program and public account submenus, while also scanning for H5 vulnerabilities.

Leveraging extensive experience in the field of application security, we deliver significant value to clients focused on securing their applications.

Comprehensive Vulnerability Detection & Root Cause Identification
With an industry-leading number of testing items, we provide full coverage of mainstream application security issues. Our system precisely identifies the root causes of vulnerabilities, supports ongoing monitoring and early warning, and offers code-level remediation samples or suggestions to help developers efficiently fix security flaws.

Unified System for Android App and SDK Testing
By submitting an Android App with one click, users can automatically detect not only app vulnerabilities but also identify integrated third-party SDKs and uncover related security risks.

Big Data-Based Vulnerability Trend Analysis
We automatically collect, clean, and analyze detection data across the platform. Key insights such as vulnerability distribution and overall app security status are visualized in multiple dimensions, providing actionable intelligence to support business decisions.

Version-Based Security Management
Our automated system enables security tracking and analysis across different app versions, supporting visualized, traceable, and manageable security operations throughout the application lifecycle.
