In the 1990s and 2000s, Rainbow Technologies (later acquired by SafeNet, then Gemalto, now part of Thales Group) produced hardware keys called Sentinel dongles. These USB or parallel-port devices stored licenses for expensive software like CAD tools, medical imaging systems, and industrial control programs.
To work, these dongles require a Sentinel System Driver – a low-level driver that lets Windows 10 communicate with the dongle as if it were a secure storage device.
