KVM switch ATEN 2-port USB HDMI Secure with CAC, 4K UHD 3840x2160@60Hz, USB keyboard/mouse, metal housing

The ATEN 2-Port USB HDMI Secure KVM Switch with CAC (PSD PP v4.0 Compliant) provides a secure way to share a single keyboard, mouse, HDMI monitor, speakers and a Common Access Card (CAC) reader between two computers of different security classifications. Designed to meet PSD PP v4.0 protection profile requirements, the device enforces isolation and unidirectional data flow between connected systems and includes always-on tamper detection in a metal housing. It supports up to 4K Ultra HD (3840 x 2160) video at 60 Hz and is powered from an AC supply.

Advantages

The switch is certified to PSD PP v4.0, delivering regulatory-compliant peripheral sharing with configurable device filtration and strict audio filtering to reduce risk of data leakage. Physical security features include an always-on chassis intrusion detection that renders the unit inoperable if tampering is detected. Manual port switching via front-panel pushbuttons or a Remote Port Selector (RPS) avoids networked control channels and helps maintain strict separation between systems.

Suitable for

• Government, defense and intelligence workstations requiring certified peripheral isolation
• Financial and banking environments handling segregated networks
• Healthcare or administrative desktops where confidential records are accessed from separate systems
• Secure control rooms and operations centers needing HDMI display support at 4K

When it may not be suitable

This KVM switch is optimized for environments that require high-assurance, manual switching and strict peripheral control. It may not be suitable for setups that require automated or software-controlled switching, network-based management, or more than two connected computers. Environments that need large-scale USB device virtualization or mass peripheral sharing across many systems should consider other solutions.

How to use

Install the unit on a desktop or in a secure rack position and connect each computer to the corresponding input ports using USB for keyboard/mouse and HDMI for video. Connect the shared monitor, keyboard, mouse, speakers and CAC reader to the switch’s console ports. Use the front-panel pushbuttons or the Remote Port Selector (RPS) to switch active control between the two connected computers. The device enforces configured USB and audio filtration and will disable operation if chassis tampering is detected.

What to consider before purchase

• Requires manual switching only (front-panel pushbuttons or RPS); no software or network switching
• Designed for two computers—verify this meets your multi-system needs
• Check that your peripherals (especially CAC reader and USB devices) are compatible with configurable device filtration rules
• Ensure your workflow requires a PSD PP v4.0 certified device for regulatory or security compliance

Recommendations

Locate the switch in a physically secure area, maintain firmware and configuration records according to your security policy, and test device filtration settings with the specific CAC reader and USB peripherals you plan to use before deployment.
