Application Security Assessments

Mobile Application Security Audit

Protect iOS & Android apps from reverse-engineering, data leakage, insecure APIs and runtime manipulation.

Request an Audit

Overview

Mobile applications have unique risks: local storage of secrets, insecure communication with backend APIs, weak certificate validation and runtime tampering on rooted/jailbroken devices. We combine static analysis, dynamic testing on real devices and API evaluation to secure mobile apps end-to-end.

Why companies need mobile audits

Mobile apps are the primary interface for many customers. A single vulnerability can lead to account theft or large-scale data leaks. Compliance, app-store reputations and customer trust all depend on secure mobile apps.

Who should get this

Mobile-first companies, fintech, health apps, enterprise mobile tools, or any app that handles authentication, payments or sensitive user data.

Key benefits

Identify insecure storage and leaked secrets

Detect improper certificate handling and MITM risk

Cover both client side and server-side API weaknesses

Recommend runtime protections and CI checks

Improve app-store security posture and user trust

Scope — What we test

Static analysis of binaries/source, insecure data storage (shared prefs, Keychain/Keystore), certificate/pinning issues, API authentication/authorization, insecure logging, client-side business logic and tamper/cheat detection bypass.

Methodology

  1. Kickoff & environment setup (test accounts, binaries)
  2. Static analysis (SAST) & dependency checks
  3. Dynamic testing on real devices and emulators
  4. Backend API testing and chaining attacks
  5. PoC creation, remediation guidance, and retest

Deliverables

Detailed report with findings, PoCs, secure code snippets, recommended runtime protections (pinning, root detection strategies), and prioritized roadmap for patches.

Timeline & pricing guide

Small app: 3–5 days. Medium app: 7–12 days. Pricing varies by number of supported platforms (Android, iOS) and whether source code is provided.

Example (anonymized)

Identified hard-coded API keys inside an Android binary and missing certificate pinning. We provided fixes and CI checks to prevent reintroducing keys into builds.

Frequently asked questions

Common questions we hear before starting an assessment — click a question to reveal a short, clear answer.

Small apps: 1–5 days. Medium: 5–10 days. Complex systems: custom timeline.

We avoid destructive checks in production and schedule high-risk tests in staging when possible.

No — blackbox tests work. Source access enables deeper code review.

Yes — PoCs, prioritized fixes and developer-focused guidance are included.

Yes — retest packages validate fixes.

Executive summary, prioritized findings, PoCs and workshop walkthroughs.

No, but source access allows deeper SAST checks and faster triage.

Yes — we can test published builds when you share credentials or via secure upload.

Yes — we provide CI/CD recommendations and SAST integration guidance.

We work with signed builds or use TestFlight/private distributions and follow secure sharing processes.
