Full spectrum protection for Android apps

    With extensive Android app obfuscation & security protocols, DexGuard provides the most comprehensive mobile app protection available. Secure your Android apps & SDKs through multiple layers of code hardening & RASP.


    We designed DexGuard to streamline the secure software development lifecycle and make developers’ lives easier while still providing robust protection.


    Optional DexGuard NDK add-on

    The DexGuard NDK add-on extends all the protection offered by DexGuard — including multi-layered Android app code obfuscation, data obfuscation and RASP integration — to included C/C++ native libraries.


    Protection Report

    DexGuard generates a Protection Report for each mobile app build that incorporates its protections. This report validates and assesses the applied protections, grading your app’s security configuration against key risk categories, providing further recommendations to improve security efficacy and surfacing potentially beneficial features to activate.


    Backwards compatible with ProGuard

    When upgrading from ProGuard (or R8) to DexGuard, you can re-use your existing ProGuard configuration file. All you need to do is account for DexGuard’s additional functionality, including its RASP and obfuscation capabilities.

    Secure Keyboard add-on

    The Secure Keyboard is designed to enhance the security of the keyboard used by your app, eliminating the risk associated with custom keyboards installed by users that may compromise data security. As a DexGuard add-on, it provides protection against malware attacks while delivering optimal UX as a fully functional keyboard.

    Defend against static analysis

    If a threat actor decompiles your app, DexGuard ensures that your code will be as resistant to reverse engineering as possible. DexGuard provides obfuscation for classes, fields, arithmetic instructions and more; code virtualization; API call hiding; and many additional security features. Crucially, DexGuard’s protection is polymorphic — each app build has a different Android obfuscation configuration, preventing a threat actor from reusing their prior knowledge.


    Counter dynamic analysis

    DexGuard automatically injects runtime application self-protection (RASP) checks, preventing threat actors from tampering with apps at runtime. What’s more, each build features different RASP checks in different locations, ensuring threat actors can’t reuse prior knowledge. DexGuard injects checks like root detection, certificate checks, hook detection and more.
