The most advanced security software for Android applications

Many mobile devices use an Android OS, but the operating system has quite a few disadvantages. A lot of free hacking tools exist that let anyone easily reverse engineer or even trojanize an Android app. There are a number of possible vulnerabilities for unprotected applications, such as insertion of malware, intellectual property theft, piracy and data theft.

DexGuard provides advanced security features tailor-made for the Android operating system. It offers protection against static analysis. DexGuard shields your apps from cloning, tampering and key extraction by applying multiple obfuscation and encryption techniques.

DexGuard also offers protection against dynamic analysis. It secures your apps against runtime behaviour modification by running environment and certificate checks. The combined layers provide the best protection for Android applications in sectors as banking, e-commerce, health, social media and gaming.

Streamline your development process

DexGuard lets you focus on your application, not on its protection. It automatically applies state-of-the-art protection techniques, saving you time, energy and money.

  • DexGuard adds multiple, mutually reinforcing layers of protection to Android applications and SDKs. Each of these layers is polymorphic, i.e. different in each single implementation.
  • DexGuard enables you to adapt the applied protection to your security and performance requirements. It also allows you to plug in proprietary algorithms for the encryption and decryption of your code.
  • DexGuard is fully compatible with ProGuard and with all common build tools and development environments (Gradle, Android Studio, Ant, Eclipse, Maven and custom builds).
  • DexGuard optimizes, obfuscates, converts to Dalvik bytecode, packages, signs, and aligns archives in a single seamless process. This optimization streamlines and speeds up the entire build process.
  • DexGuard integrates transparently in the build process: it doesn't require any changes to the source code.

DexGuard's innovative features

Code hardening


A first component of protecting your application is securing it against static analysis. This prevents hackers from finding and exploiting vulnerabilities in the application’s code while it is not running. DexGuard offers:

  • Obfuscation of arithmetic instructions, control flow, native code and library names, resources and SDK method calls
  • Encryption of classes, Cordova/Phonegap applications, strings, assets, resource files, native libraries and custom WebViews

Runtime Application Self-Protection


A second component of protecting your application is securing it against dynamic analysis. This prevents hackers from gathering knowledge of the application’s behaviour and modifying it at runtime. DexGuard offers:

  • Detection of debugging tools, emulators, rooted devices, root cloaking frameworks and tampering
  • SSL pinning and Webview SSL pinning
  • Certificate checks



Securing your application does not necessarily mean it will run slower. Optimization techniques ensure that the application retains its speed. DexGuard offers:

  • Removal of redundant code, logging code and metadata, unused resources and native libraries
  • Automatic splitting of Dex files that exceed the size constraints imposed by the Dex format
  • Resource and code optimization

Extend DexGuard with optional add-ons

DexGuard NDK


DexGuard’s plugin for the Android NDK (Native Development Kit) can harden your native libraries at an advanced level. It provides string encryption and arithmetic obfuscation.

Whitebox cryptography


DexGuard offers an SDK for whitebox cryptography, to encrypt and decrypt dynamic data with a whitebox implementation of the AES algorithm.

Secure keyboard


DexGuard offers an SDK with a keyboard implementation that is hardened against keylogging and other forms of snooping.

Device fingerprinting


DexGuard’s device fingerprinting SDK can determine the identity of devices, for instance as a parameter to assess the risk of sensitive transactions.
