Belkin's Advanced Secure DVI-I KVM Switch offers superior security and data protection for government agencies by providing true data path isolation between systems and networks. It is fully compatible with legacy and new government systems and exceeds NIAP security requirements. Using uni-directional data paths with optical diodes, it prevents peripherals from being used to leak information from one computer system to another. Additional security is provided through its end-to-end tamper-proof system that prevents physical tampering, and its intuitive user interface reduces user-switching errors by providing clear identification. Model F1DN104E supports two monitors and up to four computers.
