Black Box 4-Port Secure NIAP 4.0 Certified KVM Switch

The Black Box KVS4-1004HV is a KVM switch that lets you operate up to four computers from one keyboard, mouse, and set of displays while keeping every system completely segregated. It is purpose built for installations where data separation is mission critical.

The unit carries NIAP Protection Profile 4.0 certification, which means it meets the current United States government standard for secure peripheral sharing. Isolated data channels, non-reprogrammable firmware, and tamperproof seals work together to prevent any crossover of information, even when the connected computers sit on networks with different security classifications.

Thanks to FlexPort technology, each computer can connect through HDMI or DisplayPort, and the switch can drive single or dual monitors at up to 4K resolution with a smooth 60 Hz refresh rate. Secure EDID learning ensures the correct display settings without exposing the video path to manipulation.

Operation stays straightforward. Large front-panel buttons give you positive, tactile switching and an LED for each channel confirms which computer is active. USB 1.1 for the keyboard and mouse maintains the strictest security, while a separate USB 2.0 port supports a smart card reader or another approved peripheral.

This model suits defense command centers, corporate security teams, financial trading desks, and medical diagnostic stations where staff must move quickly between open, restricted, and classified networks without risking data leakage. The rugged enclosure and an internal anti-tamper battery discourage physical interference, so the switch can be installed on a desk or in a secure rack with confidence.
