Secure Desktop KVM Switches

Safely access servers between secure and non-secure networks.


Black Box Secure Desktop KVM Switches are TEMPEST Level 1 or 2 approved, which means they provide a high level of port-to-port electrical isolation. This port isolation facilitates data separation (RED/BLACK).


High-performance, secure KVM

These secure desktop KVM switches support USB control and connection of up to four connected PCs. Choose from switches with DVI-I or VGA support.

Prevent electronic eavesdropping

Channel-to-channel crosstalk isolation between –60dB and –80dB provides robust protection between networks, which enables secure access for agencies that connect to classified networks in addition to public networks such as the Internet.
