The free SDK allows you to virtualize critical sections (serial validation, trial counters). This is the core feature people pay Enigma for. While the full VMProtect costs money, the ability to hand-virtualize 3-4 key functions for free is an incredible defense.
ConfuserEx is powerful but user-unfriendly. The original GUI is buggy. You’ll likely use the command-line version or a third-party launcher.
