Mobile Application Security Testing
Is your mobile app and its backend secure?
Your mobile app runs on devices you don't control (in pockets, cafes and lost-and-found boxes). Whatever the app stores, sends or trusts can be reached by someone who holds the device or the network in between.
We test the app itself and the APIs behind it, so you get a picture of the whole product, not just the part the user sees.
What we test
Local storage: what the app keeps on the device, tokens, credentials, cached data
Communication: TLS configuration, certificate validation and what an intercepted connection reveals
Authentication and sessions: how the app logs in and stays logged in, and whether that can be replayed
Platform controls: behaviour on rooted or jailbroken devices, screenshots, backups
The backend APIs: with the same depth as our API security testing
The application binary: decompilation, hardcoded secrets and reverse engineering
How we test it
We agree the scope first: what to test, when, and what is off limits.
Testing combines manual work with automated tools and AI assisted analysis.
Every finding is verified by hand, with evidence captured for your team.
The weaknesses that matter
These are the kinds of findings this assessment is built to catch, each explained the way it would appear in your report.
MASVS-STORAGE
Insecure local storage
Tokens and personal data stored in plain text survive on a lost or stolen phone, readable by anyone who finds it.
MASVS-CODE
Hardcoded secrets
An API key or certificate left inside the app binary gives an attacker a starting point into the backend.
MASVS-AUTH
Weak authentication and session handling
A session that survives logout, a PIN that protects nothing, or a token that can be replayed. An attacker uses the app as a legitimate user would, and nothing tells the two apart.
MASVS-NETWORK
Weak certificate validation
The app accepts any certificate presented to it, so traffic can be intercepted, read and modified.
MASVS-PLATFORM
Platform control gaps
On a rooted or jailbroken phone, or through device backups, the app reveals data it keeps elsewhere, on devices the business does not control.
MASVS-RESILIENCE
Tampering and repackaging
The app can be modified and re-signed, so an attacker can distribute a version that records passwords or skips checks, and users cannot tell it apart from the real one.
What you receive
Executive summary written for decision-makers
Findings with severity, business impact and evidence
Practical remediation guidance for your team
Retest results after fixes are applied
When to perform it
Before release, after major updates, and whenever the app or its backend changes how it handles users.
Who it's for
Businesses with customer-facing apps on Android or iOS, and the teams building them, especially before a launch or a major release.
