Why Mobile Application Security Matters?
Mobile apps have direct access to sensitive data and device capabilities
Mobile apps access sensitive data, cameras, microphones, and location services. A vulnerability can expose all user data and device capabilities.
Mobile apps can be decompiled to extract API keys, hardcoded credentials, and business logic. Attackers can create modified versions or exploit vulnerabilities.
Users entrust sensitive personal and financial data to mobile apps. Security breaches damage reputation and violate privacy regulations like GDPR.
App stores increasingly enforce security standards. Security vulnerabilities can lead to app removal, affecting business continuity.

Which build, and which device?
The choice decides which part of the app can be examined at all.
The closest picture of real exposure, and the only way to see what the shipped build gives away. Obfuscation and pinning are in the way, which is the point.
Certificate pinning stops the proxy, so it also stops the testing of everything behind it. A build with pinning relaxed for part of the work means the traffic and the API get tested rather than the pinning.
For confirming whether a check exists at all, and for the keys and endpoints that end up in a build without anyone intending it.
Scope, and what we need from you
The quality of the result depends more on these few things than on anything else.
An APK or an IPA, with a way to install it outside the store. For iOS that means the device identifiers ahead of time, which takes longer to arrange than teams expect.
Most serious findings in a mobile app are in the API behind it, and access control between two users cannot be tested with one account.
Say so explicitly. An app assessment that stops at the app tests the smaller half of the problem, because the decisions that matter are made on the server.
Storage, resilience and platform tests need a rooted or jailbroken device. An emulator covers part of it, never all of it.
A named contact on both sides. A hard-coded key in a shipped build is reported the day it is found, not in the final report.
How each finding gets its severity
A number with no method behind it does not help anyone decide what to fix first.
Every finding is scored with CVSS v3.1, so there is a common language with your engineers and with the tools you already use.
A weakness that needs physical access to an unlocked device is not the weakness that works over the network. Both are reported; they are not ranked the same.
Each finding comes with the steps, the device state and the build it was found on. What cannot be reproduced is not reported as a confirmed finding.
The report proposes a sequence, and says which items need a new release and which can be fixed on the server without shipping an update.
Our Process
Our structured approach to mobile application security assessment
We analyze the app binary, decompile code, review hardcoded secrets, and identify potential vulnerabilities without running the app.
Runtime analysis including traffic interception, hook-based testing, and real-time monitoring of app behavior on actual devices.
Comprehensive testing of mobile API endpoints for authentication bypass, IDOR, injection vulnerabilities, and business logic flaws.
Detailed report with CVSS scores, platform-specific remediation, code samples, and free retesting after fixes are applied.

Frequently Asked Questions
Not for a standard assessment. We work from the build, which is what an attacker has. Source becomes useful for confirming whether a check exists at all rather than inferring it from behaviour, and for finding keys and endpoints that ended up in the build without anyone intending it.
Pinning is doing its job when it stops our proxy, and we test that it does. But while it holds, nothing behind it can be examined: the traffic, the API, the authorization decisions. So part of the work runs against a build with pinning relaxed, and the shipped build is tested separately to confirm the pinning itself.
Partly. An emulator is fine for traffic and much of the logic. It is not enough for the platform behaviour, for hardware-backed key storage, or for how the app behaves on a rooted or jailbroken device, which is exactly the situation the resilience controls exist for.
They are in scope as part of your app, because your users cannot tell the difference. We look at what they collect, where they send it, the permissions they pull in, and whether any of them are old enough to carry known issues. What we do not do is test the vendor product itself.
We test all types of mobile applications including native Android apps (Java/Kotlin), native iOS apps (Swift/Objective-C), cross-platform apps (React Native, Flutter, Xamarin), hybrid apps (Cordova, Ionic), and Progressive Web Apps (PWA). We also test the associated backend APIs and mobile-specific integrations.
OWASP Mobile Application Security Testing Guide (MASTG) is the comprehensive security testing methodology for mobile apps. It provides detailed test cases covering data storage, cryptography, authentication, network communication, platform interaction, and code quality. We systematically follow MASTG to ensure thorough coverage of all mobile security aspects.
MASTG (Mobile Application Security Testing Guide) is the "how to test" guide with detailed test procedures and techniques. MASVS (Mobile Application Security Verification Standard) is the "what to verify" standard defining security requirements at different levels (L1, L2). We use MASTG for testing methodology and MASVS for security verification and compliance.
Yes, we have dedicated teams for both Android and iOS security testing. Each platform has unique security considerations - Android testing includes APK analysis, root detection bypass, Content Provider security, while iOS testing covers IPA analysis, jailbreak detection bypass, Keychain security, and App Transport Security.
Timeline depends on application complexity and scope. A typical single-platform assessment takes 1-2 weeks. Dual-platform (Android + iOS) assessments take 2-3 weeks. Complex applications with extensive backend APIs may take 3-4 weeks. We provide detailed scoping and timeline estimates during initial consultation.
We use industry-leading tools including Frida for dynamic instrumentation, Objection for runtime manipulation, MobSF for static analysis, Burp Suite for API testing, jadx/Hopper for decompilation, and platform-specific tools like drozer (Android) and class-dump/cycript (iOS). Our team also develops custom scripts for specific test scenarios.
Yes, our team is experienced in bypassing various anti-tampering and root/jailbreak detection mechanisms. We evaluate the effectiveness of these protections and attempt bypasses using techniques like Frida hooking, code patching, and custom scripts. We also assess the strength of obfuscation and anti-debugging measures.
You receive: Executive Summary for management, Technical Report with vulnerability details and CVSS scores, platform-specific Proof-of-Concept documentation, Remediation Guide with platform-specific code samples, Risk Matrix prioritized by business impact, and MASVS compliance mapping. Plus a report walkthrough session and free retesting.
Yes, we offer combined Mobile + API assessment packages. Mobile apps rely heavily on backend APIs, and many critical vulnerabilities exist at the API layer. Our testing covers authentication, authorization, IDOR, injection attacks, rate limiting, and business logic flaws in the API that serves the mobile app.
Cost depends on several factors: platforms tested (Android, iOS, or both), application complexity, need for backend API testing, level of obfuscation/protection analysis, and compliance requirements. Single-platform basic assessment starts at a different price point than comprehensive dual-platform + API testing. Contact us for a free consultation and accurate quote.
