Black Box 4-Port Secure KVM Switch NIAP 4.0 Certified

The Black Box KVS4-1004D is a secure KVM switch that gives you seamless control of up to four isolated computers from a single workstation. Built to meet the strict NIAP Protection Profile 4.0 requirements, it keeps classified and sensitive networks separated through mechanical, electrical, and optical isolation, so keystrokes, video signals, and USB data never cross from one system to another.

Inside heavily regulated environments—such as defense command posts, government agencies, corporate security operations centers, or hospital imaging suites—operators often work with computers that handle different security levels. This switch lets them move between those systems with a quick front-panel button press while keeping each computer’s data completely compartmentalized. Secure EDID learning and video emulation preserve the correct resolution and picture quality up to 2560 × 1600 at 60 Hz, so critical visuals remain crisp and accurate.

The hardware-centric design adds multiple layers of protection. Isolated data channels prevent signal bleed, a non-reprogrammable ROM blocks firmware tampering, and tamperproof seals combined with a long-life anti-tamper battery reveal any unauthorized attempts to open or modify the unit. USB 1.1 and 2.0 support allows the use of standard keyboards, mice, and approved peripherals without exposing the host computers to risk.

Installation is straightforward: connect the four host PCs, attach a DVI-I monitor along with your USB keyboard and mouse, then power the switch with the included 12 V DC adapter. From that moment, users can focus on their tasks—whether drafting sensitive documents, analyzing secure data streams, or reviewing medical images—knowing that the physical switch is enforcing an uncompromising separation between every connected network.
