Black Box Secure NIAP 4.0 KVM Peripheral Defender with DVI-I & CAC

The Black Box KVS4-8001DX is a secure KVM peripheral defender that lets you share one DVI-I monitor, keyboard, mouse, and common access card reader across multiple computers without ever letting data cross between them. It is built for situations where even the smallest leak can create serious risk, such as government offices, defense installations, and any workspace that handles highly sensitive information.

Certified under NIAP Protection Profile 4.0, the unit keeps every data path strictly isolated. Video, USB, and CAC signals travel through separate, fixed channels, and the firmware is locked in non-reprogrammable ROM, so no one can load unauthorized code. Tamperproof seals and an internal anti-tamper battery signal any attempt to open the case, while secure EDID learn and video emulation maintain stable video operation without exposing monitor data.

Because the defender sits between your peripherals and the connected systems, operators can move between classified and unclassified networks with a single set of desktop devices. This setup reduces cable clutter, saves desk space, and, most importantly, removes the temptation to plug peripherals directly into high-risk machines.

The housing measures 1.05 inches high, 9.5 inches wide, and 3.7 inches deep, so it fits easily under a monitor or inside a console. A locking 12-volt power connector prevents accidental unplugging, and the unit is manufactured in the United States to meet TAA requirements. At 1.55 pounds, it is light enough to relocate yet solid enough to stay put once placed.
