Proteg Enterprise 2005 - Version 4.7 Proteg Enterprise 2005 is a software that allows usersto secure their personal or notebook computers bypreventing unauthorized access. It fortifies theexisting Windows login mechanism by binding the useraccount to a ubiquitous hardware device: A portable USBflash drive (USB Key, USB storage device, thumbdrive).An additional hardware component becomes compulsory inorder to login to the computer, instead of relyingsolely on the conventional username and password pair.Offering greater security than passwords alone, thishardware based system (commonly known as a two-factorauthentication system) creates a physical link betweena user and his identity. In a two-factor authenticationsystem like Proteg, the user is required to present thephysical hardware (something the user has) and providethe correct password (something the user knows) thatcorresponds to the said hardware in order to gainlegitimate access to the system.The sofware supports both local and Windows domain login.
