KVM-Switch ATEN 4 porte USB HDMI Dual Display Secure con CAC (4 computer, 4K UHD 3840×2160)

ATEN 4-Port USB HDMI Dual Display Secure KVM switch with CAC (PSD PP v4.0 compliant) lets one USB keyboard and mouse control four separate computers while providing two HDMI outputs per connected workstation. The CS1144H4C is designed for environments that require strict isolation between systems and peripherals, supporting HDMI video up to 4K Ultra HD (3840×2160). Its metal housing and AC 100–240 V input offer a durable desktop solution for secure multi-system management and monitoring.

Advantages

The ATEN CS1144H4C is certified to the PSD PP v4.0 protection profile and provides isolation and unidirectional data flow to prevent unauthorized data transfer between connected computers. It supports simultaneous sharing of a single keyboard, mouse, dual HDMI displays, speaker set and a Common Access Card (CAC) reader while enforcing restricted peripheral connectivity and configurable device filtering. Additional protections include strict audio filtration, tamper-resistant design, and manual switching methods to reduce attack surface.

Suitable for

• Government and defense workstations that require accredited peripheral sharing
• Intelligence and secure operations centers handling classified networks
• Hospitals and healthcare environments with segregated clinical and administrative systems
• Banks, financial institutions, and corporate environments managing separate secure networks

When it may not be suitable

This KVM switch focuses on security and manual control; it does not provide automatic or network-based switching methods. It is not intended for casual or consumer use where advanced automation or media-rich USB device sharing across systems is required.

Use the front-panel pushbuttons or the provided Remote Port Selector (RPS) to switch active consoles manually. Configure device filtering and security settings according to site policies before deployment.

What to consider before purchase

• Requires manual switching (front-panel buttons or RPS); no automatic or network switching
• Designed for secure, isolated peripheral sharing—check compatibility of specific CAC readers and USB devices
• Ensure dual HDMI outputs meet your monitor arrangement and resolution requirements
• Intended for environments that require PSD PP v4.0 compliance

Recommendations

For secure deployments, verify CAC reader compatibility, configure device filtration settings prior to connecting sensitive systems, and place the unit in a physically secure location to maintain tamper-resistant protections.
