Sangfor VDI provides a virtual desktop infrastructure solution with 3 main components - an x86 server, Sangfor VDI software, and Sangfor thin clients. It allows for centralized management of virtual desktops including single click software installation across machines. Data leakage is prevented through read-only USB access, blocking USB storage entirely, or role-based privileges while digital watermarks help trace any data leakage. The solution offers reliability through enterprise-grade servers designed for high availability and thin clients with a 10 year lifespan.
