Black Box Corporation KVS4-2004HV 8-port KVM switch

Secure 8-port KVM for classified environments

The Black Box KVS4-2004HV is an eight-port KVM switch certified to NIAP Protection Profile 4.0 for Peripheral Sharing Devices. It targets government and defence users who must isolate multiple classified or unclassified computers from a single keyboard, video and mouse console. FlexPort technology accepts either HDMI or DisplayPort on every port without adapters.

Replaces uncertified multi-head switches

This unit upgrades installations that rely on standard KVMs lacking NIAP validation, where data leakage between security domains is a documented risk. The jump is worth it when a site audit mandates Protection Profile 4.0 compliance or when dual-monitor workstations must share one console across eight sources. It does not suit buyers who need more than eight computer connections or who require USB 2.0 peripheral ports beyond keyboard and mouse.

Dual-monitor headroom with eight sources

Two FlexPort outputs drive either single or dual-monitor layouts at the resolution each source provides. Four USB Type-B inputs and two USB 1.1 Type-A console ports handle keyboard and mouse emulation with USB 2.0 compatibility. The switch runs out of headroom when a third display is required per console or when high-speed USB peripherals such as storage or audio devices must be shared.
