Black Box KVS4-2002D – 2-Port DVI-I Secure KVM Switch

Product Overview

The Black Box KVS4-2002D is a 2-port DVI-I secure KVM switch designed for high-security environments where strict data separation between systems is non-negotiable. As a NIAP-evaluated secure KVM switch, the KVS4-2002D enforces hardware-level isolation between connected computers, preventing any cross-contamination of data across ports. It is purpose-built for government, defense, intelligence, and regulated enterprise deployments where operators must access multiple classification levels from a single console while maintaining air-gap-equivalent security between sessions.

Product Description

The KVS4-2002D belongs to Black Box's KVS4-D series, a line of desktop secure KVM switches engineered to meet the stringent requirements of NIAP Protection Profile for Peripheral Sharing Switches. Each port is physically and electrically isolated using fixed-function microcontrollers, which eliminates the possibility of data leakage via software exploits, covert channels, or malicious USB device attacks. The switch supports DVI-I video — covering both digital and analog DVI signals — giving integrators flexibility when connecting to legacy or modern workstation display chains. A single set of USB HID peripherals (keyboard, mouse) is shared across both ports, with strict filtering that prevents non-HID USB devices from enumeration. The unit features tamper-evident design elements including anti-tamper epoxy sealing and chassis intrusion detection. For AV integrators and IT security teams deploying multi-domain workstations in SCIFs, command centers, or secure operations rooms, the KVS4-2002D provides a verifiable, compliant desktop KVM solution.

Key Features

• NIAP PP4.0 Evaluated — Meets the most current National Information Assurance Partnership Protection Profile for Peripheral Sharing Switches, required for U.S. government and defense deployments.
• Hardware-Enforced Port Isolation — Each port uses a dedicated, fixed-function microcontroller with no reprogrammable firmware, eliminating software-based attack vectors.
• DVI-I Video Support — Handles both DVI-D (digital) and DVI-A (analog) signals, providing compatibility across a range of commercial and government-issued workstations.
• USB HID Filtering — Only keyboard and mouse HID devices are enumerated; mass storage, audio, and other device classes are blocked at the hardware level.
• 2-Port Desktop Form Factor — Compact chassis suitable for individual operator workstations without requiring rack-mount infrastructure.
• Anti-Tamper Construction — Epoxy-sealed internals and chassis intrusion detection deter physical tampering and unauthorized inspection.
• Audio Isolation — Each audio channel is independently switched and isolated, preventing acoustic side-channel data leakage between connected systems.
• No DDC Communication — Display Data Channel is blocked between connected computers, preventing monitor-based covert channels.

Typical Applications

• Government space
• Boardroom
• Commercial meeting space
