Mobile Application Testing Services
Cyndicate Labs delivers mobile application testing services that help organisations identify security weaknesses across iOS, Android and cross-platform mobile applications.
Mobile applications process sensitive data, authenticate users, communicate with APIs, store information locally, interact with device features and operate across networks that cannot always be trusted. This creates a unique attack surface that requires specialist mobile security expertise.
Our mobile application testing covers native iOS and Android applications, modern development frameworks, mobile APIs, device-level security, platform-specific risks and application-specific vulnerabilities.
Whether your application is built using Swift, Objective-C, Kotlin, Java, React Native or other modern mobile frameworks, our consultants provide practical findings that help you protect users, data and supporting services
What is mobile application testing?
Mobile application testing is the assessment of mobile apps, APIs and supporting services to identify security weaknesses that could be exploited by an attacker.
In cyber security, mobile application testing looks at how an app handles authentication, authorisation, local storage, network communication, encryption, session management, device permissions, API requests, platform controls and backend integration.
Mobile app testing is different from standard web application testing because the application runs on a user-controlled device. Attackers may be able to reverse engineer the app, inspect local storage, modify traffic, tamper with runtime behaviour, bypass controls or interact directly with backend APIs.
Cyndicate Labs tests both the application and its operating environment, helping you understand risks across the mobile app, the device, the platform and the services it connects to.
When you need mobile application testing
Mobile application testing is valuable whenever an app handles user accounts, personal data, payment information, business workflows, sensitive content or access to backend systems.
You may need mobile application testing before launching a new app, after a major release, before submitting to app stores, during secure development, after API changes, or ahead of customer, investor, regulatory or supplier assurance reviews.
Testing is also important when applications use biometric authentication, push notifications, local databases, deep links, payment flows, device permissions, third-party SDKs, cloud services or privileged user functionality.
For high-risk applications, mobile testing should be repeated regularly and integrated into the development lifecycle so security issues can be identified before they reach production.
Benefits of mobile application testing
01
Platform-specific security
OS and Android have different security models, permissions, storage mechanisms and platform behaviours. Mobile testing helps identify risks specific to each platform and how the app uses them.
02
API protection
Mobile applications often rely heavily on APIs. Testing helps identify weaknesses in authentication, authorisation, rate limiting, session handling, data exposure and backend trust assumptions.
03
Data leakage prevention
Mobile testing helps identify sensitive data stored insecurely on the device, exposed through logs, leaked through screenshots, cached in files or transmitted without appropriate protection.
04
Store readiness
Testing helps identify issues that could affect app store readiness, customer confidence or security assurance, including insecure dependencies, weak transport security, privacy risks and poor platform hardening.
Common mobile app security risks
Mobile applications face risks that span the app, the device, the operating system and supporting backend services.
Common issues include insecure local storage, weak encryption, poor certificate validation, lack of certificate pinning where appropriate, exposed secrets, insecure API calls, excessive permissions, insecure deep links, weak authentication, insufficient authorisation and sensitive data leakage.
Android applications may be exposed to risks involving exported components, insecure intents, permissions, local storage, backup configuration, rooted devices, repackaging and runtime tampering.
iOS applications may be exposed to risks involving insecure keychain usage, jailbreak detection gaps, insecure URL schemes, local storage, weak transport security, runtime manipulation and unintended data exposure through platform features.
Cross-platform frameworks such as React Native can also introduce specific risks, including exposed JavaScript bundles, insecure bridging, dependency issues and inconsistent platform control implementation.
Cyndicate Labs assesses both application-specific vulnerabilities and mobile platform-specific behaviours, helping you understand the real-world exposure of your app across supported devices and operating systems.
Our mobile application testing approach
Cyndicate Labs tailors each mobile application test to the app, platform, architecture and risk profile.
We begin by understanding the application, user roles, data sensitivity, APIs, authentication flows, development framework and supported platforms. Testing may cover iOS, Android or both, depending on your requirements.
Our consultants perform a combination of static analysis, dynamic analysis, manual testing, API testing and on-device assessment. This may include reverse engineering, traffic interception, local storage review, authentication testing, authorisation testing, runtime analysis, platform permission review and backend API testing.
We also assess device-level considerations, including mobile platform hardening, rooted or jailbroken device behaviour, debug configuration, runtime protections, application tampering risks and platform-specific weaknesses.
Where appropriate, testing can be aligned to the OWASP Mobile Application Security Verification Standard, known as OWASP MASVS. MASVS provides a recognised framework for mobile application security requirements, while OWASP MASTG supports consistent mobile security testing through detailed processes and test cases.
Our reporting provides clear findings, evidence, risk ratings, business impact and practical remediation guidance for developers, security teams and product owners.
