VMProtect protects code by executing it on a virtual machine with non-standard architecture that makes it extremely difficult to analyze and crack the software. Besides that, VMProtect generates and verifies serial numbers, limits free upgrades and much more. Serial Numbers. The Ultimate edition of VMProtect allows to add serial numbers to the protected application with minimal efforts. The feature is supported by PayPro Global e-commerce provider, so you even doesnot need to setup your own serial number generator (of course, you can do that if you really need). Licensing feature allows to limit the period of free updates, set the time of life of serial number, prevent the code execution without serial numbers and much more. Any serial number can be blocked and newly protected files will not accept it.

Safengine provides a powerful virtual machine to protect your applications against reverse engineering or unwanted modifications. The protector will convert your sensitive code (in x86 assembly) into a random instruction set which can only be executed by the virtual machine interpreter embedded into your application after protection. These virtual machines are very unique, fully randomized and heavily obfuscated.
