You've got machines at different classification levels sharing one keyboard, one monitor, one CAC reader. One wrong keystroke or a stray audio packet and you've got a data-leak incident on your hands. That's the problem this unit kills.
The ATEN CS1144D4C is a 4-port USB/DVI dual-display secure KVM switch built specifically for PSD PP v4.0 environments. It's NIAP-certified, so it meets the Protection Profile for Peripheral Sharing Device standard without you having to argue the spec with an auditor.
What it does in plain terms: isolates each connected source from every other one. Data flows one direction only. Audio is strictly filtered. Peripheral connectivity is restricted and managed. The tamper-proof design is always on — there's no "off" switch for security.
Switching is manual. Front-panel pushbuttons or a Remote Port Selector (RPS 1). No software, no network interface, no attack surface you didn't plan for. (Heads up: the RPS isn't in the box. You'll need to source that separately.)
Built for the environments where "oops" isn't an option — defence installations, intelligence facilities, government agencies, healthcare networks, banking and finance floors. If your compliance team pointed at PSD PP v4.0 and said "that's what we need," this is the unit.
In the box: the CS1144D4C switch, a power cord, and user instructions. Plug it in, wire your four sources, and you're sharing peripherals without sharing risk
