DashO
Austin, Texas, United States
What it is
DashO is application-protection software for Android, Java, and Kotlin projects. It is designed to make reverse engineering, code tampering, and unauthorized debugging harder. Protection is applied after compilation as a build step, and PreEmptive says this can be done without changing application code. Features include Overload Induction renaming, control-flow obfuscation, and string encryption. Configurable runtime checks can detect tampering, debugging, rooted devices, emulators, and hooking frameworks, then respond based on configuration. Teams can integrate it into continuous integration using the command-line interface, Gradle plugins for Android and Java, or Ant. There is no dedicated Maven plugin, though a Maven build can call DashO through Ant. Installers are available for Windows, macOS, and Linux/GNU; the software processes Android applications and Java or Kotlin class files. Plans are quoted and vary in seat, application, and development-team allowances. A free trial is available, with no duration stated. Runtime checks may add overhead depending on configuration.
For and against
For
- Applies protection after compilation without code changes
- Includes control-flow obfuscation and string encryption
- Offers Gradle, command-line, and Ant integrations
- Free trial is available
Against
- No dedicated Maven plugin
- Runtime checks may add overhead
- Plan prices are available by quote
- No free plan
The verdict
DashO combines build-time obfuscation with configurable runtime defenses and several CI integration options. Teams should account for quote-based plans and possible runtime-check overhead when configuring protection.
Who it suits
DashO may suit development teams protecting Android, Java, or Kotlin applications as part of a build pipeline. Its plans cover small teams through enterprise teams, with allowances that vary by plan.
