PC Guard Software Protection System provides a comprehensive and robust solution for protecting software applications from unauthorized copying, distribution, and reverse engineering, while also offering flexible licensing and activation capabilities. With over 25 years of experience in software protection, licensing, and activation, it delivers secure, reliable, and compatible protection for applications developed with .NET framework, Windows .NET Core (x86/x64), Windows .NET, and native Windows 32bit and 64bit environments. The system is designed to be highly versatile, allowing developers to implement a wide array of protection scenarios including various demo modes (time, runs, period), permanent or limited licenses, license extensions, removals, and transfers. It supports features like password protection, serial number generation, IP filtering, custom features, custom counters, USB device locking, and network licensing. PC Guard is an out-of-the-box solution that by default requires no source code changes or programming experience, making it accessible to both beginners and professional software developers, who can also leverage advanced features like protection interfaces and runtime encryption. All PC Guard editions are royalty-free, enabling users to protect an unlimited number of applications with a single license, without limitations on the number of different applications, distributed applications, or activations, and without requiring additional hardware dongles. Its reliability is underscored by over 3000 clients from more than 100 countries, including major corporations like IBM, Sony, Google, HP, Siemens, Boeing, and Rolls-Royce.

Features & Benefits
