Black Box Corporation KVS4-1002HVX 2-Port Single-Monitor FlexPort HDMI/DisplayPort CAC KVM Switch

Secure KVM Switch for Classified Work

The Black Box KVS4-1002HVX is a NIAP 4.0 certified KVM switch built for environments where data separation is mandatory. It allows a single operator to control two isolated computers from one keyboard, mouse and monitor. The hardware enforces unidirectional data flow between ports to prevent leakage across security domains. It is intended for defence, intelligence and government agencies that require validated protection.

FlexPort Video and CAC Integration

Each of the two ports accepts either HDMI or DisplayPort sources through FlexPort technology, so mixed video outputs are supported without adapters. A dedicated CAC port provides smart-card reader access for authentication while maintaining port isolation. The unit ships with a 12 VDC wall-mount supply that includes US, EU, UK and AU adapter clips, plus rubber feet for desktop placement. No software drivers are required on the connected systems.

Upgrade from Non-Validated Switches

This switch replaces standard KVMs that lack NIAP 4.0 validation and therefore cannot meet strict separation policies. The jump is worth it when procurement rules demand a certified device with proven port-to-port isolation and tamper-evident construction. It is not suited for buyers who need multi-monitor support or more than two connected computers, as the hardware is limited to a single display and two ports.
