The High Sec Labs EAL4+ Secure 8/16 Port KVM Combiner Switch is a hardware device that combines KVM switch, multi-viewer, and scaler functionality in a single unit. It allows users to interact with multiple computers simultaneously while viewing all connected systems on one or two displays. The product is designed for environments where computers of different security classification levels must be operated from a single workstation without risk of data leakage between systems. It enforces hardware-level isolation between connected computer sources while allowing shared use of peripherals such as keyboard and mouse.
