Static & reverse-engineering analysis
Binary review for embedded secrets, weak crypto, and logic an attacker can lift: what your app reveals to anyone with a decompiler and an afternoon.
Cybersecurity · Security Testing
Your app ships its secrets to hardware you'll never see
The moment a user installs your app, your binary, your keys, and your API surface live on a device an attacker can own outright. Mobile security testing tells you what that access is worth: which secrets decompile out, what local storage gives up, and how far your backend trusts a client that might be lying.
Engineering-led cybersecurity and quality engineering since 2020, delivered by 100+security & quality engineers on platforms we build and run ourselves.
A flaw that ships in a mobile release can't be quietly patched; it persists on user devices through every slow update cycle. Hardcoded credentials in an APK are public the day someone bothers to look, and someone eventually bothers.
What we do
Runtime testing
Instrumented-device assessment: storage, keychain/keystore use, IPC exposure, and behavior on jailbroken or rooted devices.
Transport & API trust
TLS configuration, pinning, and what your backend assumes when the client is hostile. These are usually the highest-impact findings, because the server believes the app.
Platform-permission review
Permission scope, exported components, and data flows checked against each platform's security model.
How it’s delivered
01
Scope
Platforms, builds, and backend boundaries agreed.
02
Assess
Static, dynamic, and API testing aligned to OWASP MASVS.
03
Report
Findings with device-level reproduction steps.
04
Retest
Fixes verified on updated builds.
Tools & standards
- Methodology
- OWASP MASVS/MASTG
- Tooling
- Burp Suite Pro, instrumentation frameworks, platform analysis tooling
What you receive
- MASVS-mapped findings for iOS and Android
- A reverse-engineering exposure summary: what the binary gives away
- Backend trust-boundary findings with API reproduction
- Retest verification on the fixed builds
Evidence
Judge the reporting before you engage
Findings arrive with reproduction steps and evidence, ranked by exploitability, and fixes are verified on retest. A redacted sample report from a real engagement shows the depth before any call.

Ways to engage the same senior bench
Buy it as a scoped project, embed it in your team, or run it as a managed service. The engineers and the governance stay the same, whichever shape fits.
Point-in-time assessment
One scoped assessment with a full report and one retest: for a release gate, a customer or audit requirement, or an annual baseline.
Standing program
Recurring cycles matched to your release cadence, each closed by a retest, so the newest report is never far behind the newest release.
On-demand scope additions
A new application, API, or environment joins the existing program without re-contracting; scoping starts in days.
Who this is for
- Fintech, health, and consumer apps holding regulated data on the device
- Teams that pentest the web app every year and the mobile app never
- Products shipping SDKs or white-label apps that carry other brands' risk
Common questions
iOS, Android, or both?
Both, assessed against the OWASP MASVS/MASTG: static and reverse-engineering analysis, instrumented runtime testing, and the backend trust assumptions that are usually the highest-impact findings.
Why does mobile need separate testing from our web pentest?
Your app ships to a device an attacker fully controls. Reversible secrets, insecure storage, and weak transport are mobile-specific risks a web pentest never touches, and once a build is on user devices you no longer control how long the flaw survives.
Is retesting included?
Remediation of reported findings is verified and the report updated to 'remediated and retested', the wording auditors expect. Retest scope and window are set in the engagement agreement.
In the assurance loop
Every finding is verified on retest before a build ships. Where the same weakness could return through a future release, it is captured as an automated check. See how the loop connects →

An assessment across your iOS and Android builds shows what decompiles out, what the device stores, and how far your backend trusts a client an attacker can own.
