With four connected computers, the K204E offers impressive levels of communications, even when connecting computers that are on different levels of security clearance and Internet access. K204E utilizes unidirectional optical data-diodes which insulates all connections from any possible points of data leakage among peripherals. Every K204E secure KVM switch is rigorously and extensively tested to ensure it will remain stalwart against any known form of KVM security attacks. The unit has been certified to meet EAL 4+ standards to assure it provides the highest level of security possible.

This product offers the highest possible separation between the four connected computers. The K204E uses unidirectional optical data diodes to prevent any potential leakage between the highly-isolated peripheral channels. This KVM can also be used to securely filter and lock USB ports preventing data export/import through mass-storage devices by hardware. The K204E also features a special secured port for a Common Access Card (CAC) reader to support user authentication across multiple isolated networks.
