The Real Cost of DIY Licensing

Building licensing from scratch? Here's what you're up against.

Software Piracy

Your .NET applications can be easily copied and shared without proper licensing protection.

Unauthorized Usage

Without hardware locking, one license can be used on unlimited machines simultaneously.
