Simulate real-world attacks on both Android and iOS apps to determine how deep an attacker could penetrate via the mobile interface.
Provide actionable and prioritized insights to strengthen the mobile app’s security and protect sensitive user data.
Support compliance with security regulations and industry standards (e.g., OWASP Mobile Top 10, GDPR, PCI DSS).
Our Mobile App VAPT services are designed to address the specific needs of your mobile applications across different platforms.
Android App VAPT – Comprehensive testing of Android-based mobile applications to identify security weaknesses, including insecure data storage, weak encryption, improper implementation of APIs, and vulnerabilities to common attacks such as reverse engineering or malware injection.
iOS App VAPT – In-depth security assessment of iOS mobile apps to identify potential security flaws, improper use of device features (e.g., location services, camera), weak encryption, app data storage issues, and vulnerabilities specific to the iOS ecosystem.
Based on your app’s architecture, risk profile, and industry requirements, we provide the following types of testing:
Vulnerability Assessment (VA) for Mobile Apps – A proactive assessment that scans for known vulnerabilities in both Android and iOS applications. This helps identify weaknesses before they can be exploited by malicious actors. The VA provides a high-level overview of security risks and suggests remediation strategies.
Penetration Testing (VAPT) for Mobile Apps – A hands-on, simulated attack where our expert security testers attempt to exploit vulnerabilities in your mobile app. This deep-dive process mimics real-world cyberattacks, helping to assess how well your app can withstand advanced threats from hackers.
At Valency Networks, our Mobile Penetration Testing (VAPT) methodology follows a structured, phase-wise approach designed to deliver comprehensive coverage and accurate results. This ensures that every component of your mobile application — from client-side code to backend APIs — is tested for potential weaknesses.
Valency Networks has established a proven track record of delivering exceptional network security services to clients across various industries. Our team of seasoned cybersecurity professionals brings extensive experience and expertise to every engagement, ensuring the highest quality of service and results that exceed client expectations.
By following this structured, phase-wise approach, Valency Networks ensures that your mobile applications remain secure, compliant, and resilient against real-world cyberattacks — protecting both your users and your business.
At Valency Networks, we combine the precision of automation with the expertise of manual testing to deliver a comprehensive Mobile Application Vulnerability Assessment and Penetration Testing (Mobile VAPT). Our goal is to uncover both technical and logical flaws across Android and iOS platforms — ensuring your mobile apps remain resilient against real-world cyber threats.
We utilize advanced automated tools to detect known vulnerabilities, insecure configurations, and potential weaknesses across Android and iOS applications. These tools help accelerate testing and provide a foundation for deeper manual validation.
Key Tools:
Manual testing enables us to uncover business logic flaws, authentication issues, and vulnerabilities that automated tools often overlook. Our specialists perform in-depth testing of:
Data at Rest (DAR):
We evaluate how the application stores data locally on the device. This includes checking for:
Data in Transit (DIT):
We assess how securely the app transmits data between the device and backend servers. Our tests include:
Ensuring sensitive data (like tokens or PII) is never transmitted in plaintext.
This combined focus on DAR and DIT ensures that user data remains secure throughout its lifecycle — both on the device and in motion — reducing the risk of data breaches and unauthorized access.
In today’s threat landscape, securing mobile applications is critical to protecting user data, maintaining compliance, and preventing cyberattacks. At Valency Networks, our Mobile App Security Testing Checklist ensures that every layer of your Android and iOS apps — from authentication to encryption — is thoroughly tested for vulnerabilities
This Mobile App VAPT checklist helps organizations and development teams systematically identify security vulnerabilities across Android and iOS applications before they can be exploited. By evaluating authentication, authorization, data storage, network communication, input validation, error handling, code integrity, and third-party components, teams can prioritize and remediate risks effectively.
It ensures that mobile apps are resilient against real-world attacks, including session hijacking, reverse engineering, API abuse, and business logic exploitation. Following this checklist also supports compliance with industry standards and regulations such as OWASP Mobile Top 10, GDPR, HIPAA, and PCI DSS. By integrating these VAPT checks into the development and QA process, organizations can strengthen overall security posture, protect sensitive data, and maintain user trust, while delivering mobile applications that are robust and secure.
Verify strong authentication mechanisms (MFA, biometrics), proper session handling, and role-based access control to prevent unauthorized access, session hijacking, and privilege escalation.
Assess secure storage of sensitive data on devices (Data at Rest) and secure transmission (Data in Transit). Check encryption practices, key management, and protection of passwords, tokens, and personal data.
Ensure all network traffic uses secure protocols (HTTPS/TLS) with proper certificate validation and no insecure channels. Test backend APIs for exposure, data leakage, and authorization flaws.
Test for vulnerabilities like SQL injection, XSS, command injection, and business logic flaws. Verify both client-side and server-side input validation to prevent malicious activity and workflow manipulation.
Review the app source code for hardcoded secrets, insecure dependencies, and improper cryptography. Validate obfuscation, tamper-resistance, and ensure third-party libraries are up-to-date with minimal permissions.
Ensure error messages do not leak sensitive information. Verify secure logging of events, adherence to regulatory standards (GDPR, HIPAA, PCI DSS), and alignment with OWASP Mobile Top 10 best practices.
Mobile application security testing involves two complementary approaches: Dynamic Application Security Testing (DAST) and Static Application Security Testing (SAST). Both are essential for identifying vulnerabilities, but they differ in methodology, timing, and coverage.
Mobile DAST: Tests a running mobile app by simulating real-world attacks and analyzing responses in real-time.
Mobile SAST: Examines the app’s source code or binary without execution to detect insecure coding practices and potential vulnerabilities.
Mobile DAST: Performed on a live app (device or emulator) during runtime, assessing backend interactions and external dependencies.
Mobile SAST: Conducted during development, allowing early detection of code-level vulnerabilities before deployment.
Mobile DAST: Broad runtime coverage, including frontend, backend, APIs, and third-party interactions.
Mobile SAST: Deep code-level analysis of source code or binaries, including third-party libraries and dependencies.
Mobile DAST: Faster and more automated, requiring no source code access; ideal for runtime testing.
Mobile SAST: Slower but provides precise code insights; can be integrated into CI/CD pipelines for early feedback.
Mobile DAST: May produce more false positives due to runtime behavioral analysis.
Mobile SAST: Typically fewer false positives because vulnerabilities are identified directly in the code.
Mobile DAST: Limited coverage of external libraries and dependencies.
Mobile SAST: Comprehensive analysis of all code dependencies, including third-party libraries.
Mobile DAST and SAST are complementary approaches. Using both ensures thorough vulnerability coverage, from code-level flaws to runtime behavior, helping organizations strengthen mobile app security effectively.
Android applications can be exposed to various security risks that compromise user data and app integrity. Identifying these vulnerabilities early is crucial for building secure and resilient apps. Common security issues include:
By addressing these common Android security issues through secure coding practices, regular VAPT assessments, and adherence to best practices, developers can strengthen their apps, protect user data, and reduce the risk of cyberattacks.
Mobile application security requires a combination of automated and manual testing to uncover vulnerabilities and protect sensitive data. Both approaches complement each other and ensure a thorough security assessment.
Automated VAPT uses specialized tools and scanners to quickly detect known vulnerabilities, such as insecure data storage, weak authentication, and unsafe communication channels.
Advantages: Fast, scalable, and efficient; identifies common issues across large codebases.
Limitations: May produce false positives/negatives and can miss complex vulnerabilities requiring human insight.
Manual VAPT relies on the expertise of security professionals to conduct in-depth analysis, reverse engineering, and creative testing.
Advantages: Detects complex vulnerabilities and context-specific issues missed by automated tools; provides deeper insights into the impact of security flaws.
Limitations: Time-consuming, resource-intensive, and dependent on tester expertise.
Synergy: Automated scans identify low-hanging vulnerabilities quickly, while manual testing uncovers deeper, sophisticated issues.
Iterative Process: Automated results are validated and expanded through manual analysis to ensure accuracy.
Continuous Improvement: Integrating automated and manual testing into the development lifecycle helps catch vulnerabilities early and adapt to evolving threats.
By leveraging both approaches, organizations gain comprehensive mobile app security coverage, mitigate risks effectively, and protect sensitive user data.
