dotNet Protector is a powerful .NET code protection system that prevents your assemblies from being decompiled. With dotNet Protector, your application is not simply obfuscated, but merged in a Win32 native executable; Console exe, windows exe and windows services can be protected.

Protection can be done interactively with an intuitive graphical interface, or automated, using the command-line functionalities of dotNet Protector. dotNet Protector includes a powerful hardware sensitive anti-piracy system and extensions to help you develop your own software activation system. dotNet Protector is self-protected and uses its internal software activation system. Even multi-domain applications can be fully protected. dotNet Protector includes extensions permitting in-memory execution in another domain.
