Virbox Protector encrypts and hardens software to help enterprises protect intellectual property and commercial value after delivery. It covers local programs, mobile apps, Java, .NET and Python software, Unity projects, SDKs, static libraries, object files, and AI models. Supported languages and frameworks include C, C++, C#, Java, Python, VB, PB, 易语言, and PHP. Protection strategies include code virtualization, obfuscation, encryption, and compression. The Native product protects PE, ELF, and Mach-O programs against decompilation and reverse analysis, and can encrypt configuration, resource, and script files. It supports command-line automation for CI integration and says its process does not upload developer or program information. Separate offerings provide offline hardening for Android SDK JAR and SO files inside AAR packages, and Java protection for JAR, WAR, and CLASS files. Java trial-encrypted programs run for only seven days and are not meant for formal release. A trial is available, but there is no free plan. The pricing note lists a starting price of $299/yr; separately listed licenses include 2499.00 CNY for Native X86 personal use and 6499.00 CNY for Native X86 enterprise use.
