Black Box Secure 4-Port NIAP 4.0 KVM Switch with DisplayPort MST

The Black Box KVS4-1004VM is a secure KVM switch designed for workstations where absolute data separation is non-negotiable. It lets you operate up to four computers that present DisplayPort video while sharing one keyboard, one mouse, and either one or two HDMI displays. By integrating Multi-Stream Transport, the switch can extend or mirror each computer’s desktop across two screens, making multitasking and side-by-side comparison straightforward.

Certified to the NIAP 4.0 Protection Profile, the unit creates an air-gap between systems that sit on different security levels or networks, so classified and unclassified data never touch. Tamper-evident seals and secure EDID emulation further block hidden channels that might leak information. If your environment relies on Common Access Cards, an optional CAC port allows smart-card authentication without compromising the isolation of connected machines.

Video quality stays sharp at up to 4K resolution at 60 Hz, an advantage for analysts who deal with high-detail maps, engineers reviewing CAD drawings, or corporate operators who monitor multiple dashboards at once. Front-panel push buttons make it easy to move from one computer to another, reducing desktop clutter and eliminating the need for several sets of peripherals.

Whether you are outfitting a defense command center, a secure control room, or an enterprise operations desk, the KVS4-1004VM delivers reliable switching and peace of mind in a single, purpose-built appliance.
