Find out what is actually exposed in your mobile application.

The RiverSafe Mobile Application Security Assessment tests your mobile application the way an attacker would, working across the binary, the APIs it calls, and the third-party SDKs it ships.

You get a MASVS maturity score, a validated finding set with no false positives, and a remediation roadmap your engineering team can pick up straight away.

Assessment Scope

Layer 1

Mobile Application Binary (iOS / Android / Hybrid)

  • Static analysis: code structure, hardcoded secrets, insecure configurations, certificate pinning
  • Dynamic analysis: runtime behaviour, memory inspection, traffic interception
  • Jailbreak and root detection bypass
  • Anti-tamper and obfuscation resilience
  • Repackaging and instrumentation resistance

Layer 2

API & Backend Services

  • Authentication and authorisation: token handling, session management, privilege escalation
  • Data exposure: sensitive data in responses, mass assignment, IDOR
  • Business logic: transaction manipulation, workflow bypass, rate limiting
  • Input validation and injection surface

Layer 3

Third-Party SDKs & Supply Chain

  • SBOM generation across all embedded dependencies
  • Outdated, unmaintained, or risky library identification
  • Compliance exposure: SDKs collecting or transmitting data inconsistent with privacy obligations
  • Known CVE exposure across the dependency set

Discovery to maturity score in four weeks.

Our Assessment takes place over five phases, each with defined outputs. You know what is happening at each stage and what comes out of it.

 

Phase 1 Discovery and Context

Gold Flow session to map the journeys and data flows that carry real risk. Produces the threat model and testing priorities.

Phase 2 Environment Setup

Build access established, staging environment validated, toolchain configured.

Phase 3 Adversarial Assessment

Human-led testing across binary, APIs, and supply chain under adversarial conditions.

 

 

 

 

 

 

 

 

 

 

 

Phase 4 Remediation Clinics

Working sessions with engineering teams to demonstrate attack paths and work through fixes.

Phase 5 Maturity Score and Report

Scorecard, executive summary, technical report, and prioritised roadmap delivered in a single working session.

What you receive:

  • MASVS Maturity Score Card

    A maturity score across all OWASP MASVS-aligned domains

  • Executive Summary

    Covers the assessment findings, current maturity position, risk exposure, and where to direct investment.

  • Technical Assessment Report

    All confirmed findings go directly into your existing tracker with severity and priority mapped to your conventions.

  • Prioritised Remediation Roadmap

    Recommendations for what to fix, in what order, based on risk reduction per effort.

  • False Positive Guarantee

    Every finding is confirmed as real before it is reported. If RiverSafe raises an issue, it has been validated and can be reproduced

MAST Assurance Programme

The assessment tells you where you are. The MAST Assurance Programme provides continuous coverage as your application changes, testing new releases, integrating into your delivery pipeline, and tracking maturity over time.
