Uncompromising Android app protection

Connect with an expertDownload the DexGuard fact sheet

DexGuard

Defend against static analysis

Apply in-depth protection against reverse engineering. Layered techniques such as data encryption, control flow obfuscation, code virtualization and name obfuscation keep logic hidden.

  • Protect your IP and prevent extraction of secrets and sensitive information
  • Hide sensitive code related to authentication, transactions, and in-app purchases
  • Prevent exposure of backend APIs and request logic

Counter dynamic analysis

Prevent runtime tampering and inspection. Ensure continuous integrity of your code and its execution environment.

  • Block function hooks, dynamic instrumentation, and other code changes.
  • Act on tampered system libraries, emulators, virtual environments, and root privileges.
  • Defend against overlays, a11y abuse, and other malware techniques.

How DexGuard works

Polymorphic, compiler-based approach

Comprehensive and evolving security

Having defenses injected and applied during code compilation avoids the common pitfalls of SDK-based protection (i.e., “wrappers”).

DexGuard applies polymorphic obfuscation techniques and automatically injects endless variations of integrity checks throughout your existing code. No two protected builds ever look the same.

  • Reset the clock on reverse engineering, rendering any gained knowledge useless with each app release.

  • Conceal the boundaries between your application logic and the protection code for reinforced security.

  • Unique protections with every build ensure that lessons from attacking other applications don't apply to your app.

Mutually reinforcing protection layers

A force multiplier for your mobile app’s security

DexGuard’s multi-layered defenses provide robust Android mobile app protection against static and dynamic analysis.

  • Overlapping obfuscation layers reinforce each other. After code semantics are stripped and logic is obfuscated, the app can be virtualized and encrypted.

  • Obfuscated RASP checks verify environment integrity. These checks are then verified by other code integrity RASP checks.

  • Malicious inspection and modification of code is prevented by ensuring the environment has normal privileges, is free of debuggers, and is an actual physical device.

Highest level of protection, in less than a day

Configure maximum protection with ease

Weaving multi-layered protection into your existing application logic historically required detailed insight into your application as well as fine-grained configuration capabilities.

Guardsquare's unique guided workflow reduces this process into two simple steps, and is proven to take less than a day.

  • Create an instrumented version of your app.

    DexGuard automatically collects all the required application information.

  • Customize your protection.

DexGuard TL;DR

DexGuard is Guardsquare’s mobile app protection product, built specifically for Android applications.

DexGuard protects against reverse engineering, tampering, and other sophisticated mobile app threats through a combination of code-hardening (multi-layered obfuscation and encryption techniques), automated runtime application self protection (RASP) checks, and built-in malware defenses.

DexGuard establishes comprehensive mobile app protections that can help organizations meet compliance and regulatory goals. This includes requirements for data privacy (GDPR, CCPA, LGPD), financial services (PSD2, PCI), healthcare (FDA, EU-MDR), and more.

DexGuard is compatible with both Android Studio and Gradle. Adding it to your project is easy and allows for a transparent integration with your build.

DexGuard is designed to protect applications downloaded from the Google Play store.

In-depth mobile application security must include layers of protection to defend against the ever-evolving tools and techniques employed by attacks in the wild. As a compiler-based tool, DexGuard provides more robust protection than app shielding or wrapper tools.

DexGuard and iXGuard are both part of Guardsquare’s mobile app protection tool offerings. DexGuard is our product built specifically for Android applications and iXGuard is our product built for iOS applications. Conceptually, the products are very similar and protect against roughly the same threats. The primary difference is specific to the technology differences in Android vs iOS apps.
