ATEN CS1142DPH4C 2-Port 5K DisplayPort/HDMI Secure KVM Switch with CAC – PSD PP v4.0 Compliant

You're running two machines at different security levels and you need one keyboard, one monitor, one CAC reader — without a single byte leaking between them. The ATEN CS1142DPH4C does exactly that. It's PSD PP v4.0 compliant, NIAP certified, and it isolates data flow the instant you flip the port. No software layer. No network path for data to slip through.

You get 5K (5120 × 2880 @ 60Hz) on dual displays through a single DisplayPort/HDMI combo connector. USB peripherals — keyboard, mouse, speaker set, CAC reader — share across both sources. Switching is manual only: front-panel pushbuttons or the Remote Port Selector (RPS sold separately). That's deliberate. Fewer moving parts, fewer attack surfaces.

Built for defence, intelligence, healthcare, banking, and any environment where 'oops, wrong port' isn't an option. At $1,594 RRP, it's not a weekend tinker — it's the piece that keeps your classified sessions locked down while you work side by side on dashboards and data-heavy apps without task-switching errors.
