DexGuard starts from the functionality of ProGuard. It makes your apps smaller (10% - 70%) and faster (10% - 20%). It is entirely specialized for Android, thus providing stronger features. It optimizes and protects code and resources as a whole. Above all, it focuses on protecting your code: obfuscation, hiding sensitive strings, keys, and entire algorithms from prying eyes and attackers.

DexGuard Enterprise adds specialized features. It also protects the resources in your application with strong obfuscation techniques. It dynamically checks the environment in which your application runs, with techniques like root detection and SSL pinning. The combined layers provide the best protection for applications in banking, e-commerce, health, etc.

"We have undergone a security evaluation by an independent lab and the protection of the code was deemed very good. So congratulations!"

DexGuard offers passive protection and optimization:

  • Optimize and obfuscate. DexGuard extends the industry-standard features of ProGuard with configuration and processing tuned for the Android platform.
  • Encrypt strings. Thwart hacking through trivial searches, by specifying the strings that should become invisible in your code. DexGuard encrypts the strings for you, so you don't have to burden your source code and your development process.
  • Encrypt entire classes. Hide important code like license checks or paid downloads, by specifying entire classes that should be encrypted. DexGuard does this transparently and effectively.
  • Obfuscate native code. Obfuscate the names of native methods in Dalvik bytecode and in native code.
  • Encrypt native libraries. Let DexGuard put up a barrier against reverse-engineering of your native code.
  • Hide access to sensitive APIs. Further harden your code, by letting DexGuard insert reflection to access sensitive APIs, like the standard Android APIs for signature validation or cryptographic operations.
  • Thoroughly remove Android logging code. Develop with logging, debugging, and testing code, and just leave it to DexGuard to remove it from your released code.
  • Remove unused resources. Remove unused resources and resource files.
  • Optimize resources. Optimize not only the code, but also the resources (constant propagation in resources and code).
  • Automatically split Dex files. If you're running into the size constraints of the Dex format, let DexGuard split your code into multiple Dex files. It automatically takes care of all the necessary dynamic loading, reflection, and packaging for you.

DexGuard Enterprise offers additional passive and active protection:

  • Obfuscate resources. Obfuscate the names of resources, resource files, and resource XML attributes.
  • Encrypt assets. Encrypt asset files.
  • Check the certificate. Check if the app has been signed with the original certificate.
  • Add tamper detection. Let your application react accordingly if a hacker has tried to modify it or is accessing it illegitimately.
  • Add environment checks. Check if the device has been rooted (or is using an anti-root-detection framework like Xposed or Cydia Substrate). Check if the app is being debugged or is being run in an emulator.
  • Perform SSL pinning. Make sure that the app is connecting to the intended server in your code.
  • Protect WebViews and Cordova/Phonegap apps. Encrypt the contents of a WebView or a Cordova application (html, css, js,...).

Get started quickly. DexGuard helps streamlining your development.

Speed up your builds.

Reuse any custom
ProGuard configurations.

Stick to your favorite
build process.

Learn from our examples.

DexGuard optimizes, obfuscates, converts to Dalvik bytecode, packages, signs, and aligns archives all in a single seamless process. This optimization streamlines and speeds up the entire build process. Shorter development/test cycles make the development process more pleasant and effective. DexGuard is fully compatible, so you can continue leveraging your expertise and the community's expertise on ProGuard. DexGuard integrates transparently in Android Studio, Eclipse, Gradle, Ant, and Maven. You can also plug in DexGuard in your custom builds or even run it as a command-line tool. Just continue using the development processes that you know. DexGuard comes with working samples that illustrate its features, for instance hardening Google's License Verification Library, the in-app billing library, the AdMob library, Amazon's in-app purchasing library, etc.

In short, 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.
