Black Box 4-Port Secure NIAP 4.0 Certified CAC KM Switch

The Black Box KVS4-1004KX is a keyboard and mouse switch that lets you operate up to four separate computers while keeping each system completely isolated. Certified to the NIAP Protection Profile 4.0, it brings a level of security that meets the demands of government agencies, defense contractors, and any organization that must protect classified or sensitive information.

With a single set of USB Human Interface Devices, you can move seamlessly from one computer to the next. Cursor navigation happens smoothly across connected monitors, and the built-in switching logic ensures that audio and Common Access Card peripherals follow your focus. Because data flows in only one direction, the switch blocks hidden channels that could otherwise leak information between networks. Mechanical, electrical, and optical isolation add another layer of protection, while tamper-evident seals and protected firmware make unauthorized changes easy to detect.

The switch is equally at home in a secure command center, an emergency call hub, or a military field office where operators must manage systems on different security domains without risking cross-contamination. Installation is straightforward: connect the computers, plug in your keyboard, mouse, and optional CAC reader, then power up. From that point, users can concentrate on their mission knowing every keystroke and every click stays confined to the chosen computer.

Made in the United States and fully TAA compliant, the Black Box KVS4-1004KX delivers security you can verify and reliability you can trust.
