Mobile App Security Testing
Mobile apps store secrets, talk to APIs and run on untrusted devices. We test your iOS and Android apps against the OWASP Mobile Application Security Verification Standard - static, dynamic and runtime - to find what attackers would.
Typical timeline
8–12 business days
Engagement model
Grey / black / white box
How it runs
Kickoff → test → report → re-test
Overview
Mobile applications operate in an untrusted environment where attackers can easily reverse-engineer binaries, intercept network traffic, and manipulate runtime memory. Standard web application scanners are blind to the unique vulnerabilities of native and hybrid mobile apps.
Our mobile application security testing follows the OWASP Mobile Application Security Verification Standard (MASVS). We combine deep static analysis (binary reverse engineering, hardcoded secrets detection) with dynamic analysis (traffic interception, cryptographic checks) and runtime manipulation to ensure your iOS and Android applications cannot be compromised.
At a glance
- Static & dynamic analysis (SAST + DAST)
- Insecure storage, transport and crypto findings
- Runtime manipulation and tamper testing
- Backend/API abuse via the mobile client
Coverage
What we cover
Reverse Engineering
Testing binary obfuscation, anti-decompilation, anti-debugging, and root/jailbreak detection.
Data Storage & Privacy
Inspecting Keychain, Keystore, local SQLite databases, and cache files for sensitive data exposure.
Network & Cryptography
Verifying SSL pinning, TLS configuration, and checking for weak cryptographic algorithms.
Runtime Instrumentation
Attempting runtime modification and bypasses using frameworks like Frida and Objection.
Authentication & IPC
Testing custom URL schemes, deep links, broadcast receivers, and local authentication flows (Biometrics).
Backend API Posture
Intercepting and probing the API endpoints exposed specifically to the mobile client for auth/authz flaws.

Why A5
Why teams pick us
Manual-first, not scan-first
Senior testers hand-craft test cases for your business logic - scanners only set the baseline.
Proof, not guesses
Every finding ships with a working proof-of-concept and exact reproduction steps.
Fix-focused reporting
Remediation with code and config examples, not just a CVSS number and a shrug.
Re-test included
We verify your fixes and issue a clean report - closure, not just discovery.
FAQ
Frequently asked
Do you need source code?
Grey-box (with source) gives the deepest results, but we also perform black-box testing on the published binary.
