OWASP Mobile Top 10
API Communication Review
Android and iOS testing that covers the device — insecure storage, weak reverse-engineering resistance — and the backend API calls behind it, using a methodology aligned with the OWASP Mobile Top 10.
Beyond web-only testing
Your web app was tested. Your mobile app is a different attack surface entirely.
Insecure local storage, exposed logs and reverse-engineering exposure live on the device itself — risks a web-focused test simply doesn’t reach. A mobile-specific methodology, aligned with the OWASP Mobile Top 10, is needed to catch them.
Data storage risks the web can’t see
Insecure local storage, cache and logs checked for sensitive data left unprotected on the device.
Client and API tested together
The app and the backend calls it makes are tested as one system, not two separate engagements.
Reverse-engineering resistance
Assessing how easily the binary can be decompiled or manipulated, and what it exposes.
Platform-specific methodology
Android and iOS have different security models, so each is tested to its own standard.
Flexible testing depth
Black-box, grey-box or white-box with source code — confirmed with you during scoping.

The short version
What Is Mobile Application Security Testing?
Mobile apps introduce risks distinct from web applications — data stored insecurely on the device, sensitive information left in logs or cache, weak protection against reverse engineering, and API communication that can be intercepted or manipulated if not properly secured. A mobile-specific testing methodology, aligned with the OWASP Mobile Top 10, is needed to catch these risks, since a standard web application test won’t cover device-specific attack surface.
Two surfaces are tested as one, using a methodology specific to each platform:
Client-Side Testing
Binary analysis, local storage and reverse-engineering resistance on the installed app.
API & Backend Testing
The backend calls the app makes, tested independently of the client — often the more exposed layer.
Platform-Specific Methodology
Android and iOS tested to their own security models — not one generic checklist.
What we test
Every layer your app touches — the device, the binary, and the wire.
Platform-specific testing across Android and iOS, plus the API traffic connecting your app to its backend.
A common — and costly — assumption
Testing your web app doesn’t mean your mobile app is covered too.
It’s a common assumption that a company’s web application review also covers its mobile app — but mobile apps introduce their own attack surface that web-focused testing simply doesn’t touch.
The assumption that costs you
Left untested, and exposed.
Assuming a web app pentest already covers the mobile client.
Missing device-specific risks like insecure local storage or exposed logs.
Treating the client app and its backend API as separate testing concerns.
Shipping a binary that reverse engineering exposes hardcoded secrets in.
Tested the way attackers approach it
Client and server, together.
Platform-specific methodology for Android and iOS, aligned with the OWASP Mobile Top 10.
Local storage, cache and logs checked for sensitive data left unprotected.
The client app and its backend API tested together as one system.
Binary analysis for hardcoded secrets and reverse-engineering exposure.
How it runs
From binary to backend, tested in a fixed sequence.
A structured pass through the app itself, its running behavior, and the APIs it depends on.
01
Static analysis
Analyzing the app binary for hardcoded secrets, insecure configurations and code-level weaknesses.
02
Dynamic analysis
Testing the running application’s behavior, including data storage and runtime protections.
03
API & backend testing
Testing the APIs the app communicates with independently of the client, since this is often the more exposed layer.
04
Auth & session testing
Testing login, token handling and session management for mobile-specific weaknesses.
05
Reporting & retest
Findings with severity scoring and remediation guidance, then a free retest once fixes are applied.
