About Us

Security solutions built by industry professionals.

DotFix Software has been developing decompilers, disassemblers, and software protection solutions for over 20 years. We are the creators of the well-known VB Decompiler, giving us detailed insight into software internals and the techniques used to analyze and compromise applications.


We use this reverse-engineering knowledge to build better defenses. Our flagship protection product, DotFix NiceProtect, is designed to counter modern analysis and reverse-engineering techniques. It supports a wide range of native compilers (Delphi through version 13 Florence, Visual C++, VB6, and Qt) and provides multi-layered protection for applications running on Windows XP through Windows 11.


DotFix NiceProtect is designed by engineers with deep machine-code and executable-format expertise. Explore the protection technologies to learn how its defenses work.
