Mobile
Security

Deep iOS and Android testing from client binary to backend APIs.

Our mobile security engagements evaluate app logic, device-side controls, transport handling, and API trust boundaries to expose practical attack paths.

OUTCOMES
  • Validated client-side and API trust assumptions
  • Reduced exposure of sensitive data on device and transit
  • Clear remediation plan for secure mobile release cycles
DELIVERABLES
  • Mobile app penetration test report with evidence
  • Source-assisted review findings where available
  • Threat model aligned to app features and business risk

WHAT WE TEST
  • ›Client binary reverse engineering and runtime behavior
  • ›Local storage, secrets handling, and transport controls
  • ›Authentication and session security paths
  • ›Backend API trust and mobile-specific abuse cases
BEST FOR
  • ›Fintech, healthcare, and high-trust mobile apps
  • ›Teams preparing major app launches
  • ›Organizations with sensitive customer data in mobile workflows
TYPICAL TIMELINE

Mobile assessments usually run 2-3 weeks, depending on platform count, app complexity, and API surface.

FAQ

Can you test both iOS and Android in one engagement?

Yes. We can test both platforms and compare security control parity across implementations.

Do you need source code access?

Source access helps depth, but we can perform strong black-box and gray-box testing without full code.

Will this include API testing tied to the app?

Yes. Mobile API paths are tested as part of the end-to-end trust boundary and abuse model.
