Best 17 Mobile App Security (MAST) Tools 2026

Q: What is mobile application security testing?

Mobile application security testing analyzes iOS and Android apps for vulnerabilities specific to mobile platforms: insecure data storage, weak cryptography, improper session handling, and platform misconfigurations. It includes static analysis of the app binary and dynamic analysis of runtime behavior.

Q: What is OWASP MASVS?

OWASP MASVS (Mobile Application Security Verification Standard) defines security requirements for mobile apps. It covers data storage, cryptography, authentication, network communication, platform interaction, and code quality. Mobile security tools often map findings to MASVS requirements.

Q: Can I use SAST tools for mobile apps?

Some SAST tools support mobile languages (Swift, Kotlin, Java), but they miss platform-specific issues. Dedicated mobile security tools analyze the compiled binary and test runtime behavior, catching issues that source code analysis misses.

Q: What is the difference between MAST and DAST?

MAST (Mobile Application Security Testing) is specifically designed for mobile apps and understands iOS/Android platform specifics. DAST tests web applications from the outside. While mobile apps often have API backends that DAST can test, the mobile app itself needs MAST for comprehensive coverage.

Q: Is there a free mobile security tool?

Yes. MobSF (Mobile Security Framework) is fully open-source and supports both iOS and Android. It performs static and dynamic analysis and is widely used for mobile app security testing. Commercial tools add features like device farm testing and enterprise reporting.

What is Mobile Application Security Testing?

Mobile Application Security Testing (MAST) is the practice of analyzing iOS and Android applications for platform-specific vulnerabilities by examining compiled binaries, runtime behaviors, and device-level interactions that traditional web-focused security tools cannot detect. MAST tools understand mobile-specific security models, binary formats (APK, IPA), and platform APIs that differ fundamentally from web applications.

Mobile apps face distinct security challenges that general-purpose tools miss entirely: insecure local data storage, weak cryptography, improper keychain/keystore usage, certificate pinning bypass, and platform API misuse.

Traditional SAST and DAST tools were designed for web applications and lack the ability to inspect compiled mobile binaries or instrument device runtimes.

The mobile application security market was valued at $454.4 million in 2024 and is projected to reach $2.86 billion by 2032 at a 25.9% CAGR (Fortune Business Insights, 2025), reflecting how seriously organizations now treat mobile-specific risks.

MAST combines three testing approaches: static analysis of the compiled binary, dynamic analysis on physical devices or emulators, and interactive testing with runtime instrumentation. MobSF is the only free all-in-one framework supporting both iOS and Android, while commercial tools like NowSecure and AppKnox add cloud device farms, OWASP MASVS compliance mapping, and enterprise reporting.

How Has the Mobile Security Market Changed?

The mobile security market shifted dramatically between 2024 and 2026, driven by new OWASP standards, stricter privacy regulations, and the move toward DevSecOps integration.

A few years ago, most mobile security tools focused on one platform. That’s no longer the case, and here’s what I’m seeing now:

Everything is cross-platform now. Nearly every tool supports both iOS and Android. The days of picking a single-platform specialist are mostly over.
Privacy jumped up the priority list. GDPR enforcement, CCPA fines, and Apple/Google tightening app store rules pushed vendors to add privacy analysis. NowSecure made data protection a core feature, not an afterthought.
Supply chain risk hit mobile. The 2024 OWASP Mobile Top 10 added supply chain security as a new category (OWASP, 2024). Tools are catching up with third-party SDK analysis, but it’s still early.
CI/CD plugins are table stakes. Zimperium zScan and AppKnox ship GitHub Actions and Jenkins plugins. If a tool can’t plug into your pipeline, I’d skip it.
Real device testing went cloud. Running your own device lab is painful and expensive. esChecker built its whole product around cloud device farms, and most commercial tools followed.

How to Choose a Mobile Security Tool

Platform Coverage

iOS only? Android only? Both? Start here. MobSF covers both platforms well. Some commercial tools technically support both but are clearly stronger on one side, so check their documentation before buying.

Static vs Dynamic

Static analysis slots into CI/CD pipelines with minimal friction. Dynamic analysis gives you deeper coverage but needs devices or emulators to run, which complicates automation. Ideally you want both. Most commercial tools bundle them together.

Device Infrastructure

Dynamic testing needs actual devices, and maintaining your own device lab is a headache (OS updates, hardware failures, physical space). esChecker and NowSecure handle this with cloud device farms. If you go self-hosted, budget for the overhead.

Compliance Requirements

Regulated industry? You probably need OWASP MASVS compliance reports. NowSecure and AppKnox generate reports mapped directly to MASVS controls, which saves you from manually cross-referencing findings.

Budget and Scale

MobSF is free and handles the basics well. Ostorlab has a freemium tier if you want something in between. Commercial tools like AppKnox justify their cost with lower false positive rates and dedicated support, which matters more as your app count grows.
