ATEN CS1144D4-AT-U | 4-Port USB DVI Dual Display Secure KVM Switch, PSD PP v4.0, No CAC

The ATEN CS1144D4 is a 4-port USB DVI dual-display secure KVM switch built to meet the rigorous security demands of defence, intelligence, government, and financial environments. Certified by NIAP to PSD PP v4.0 (Protection Profile for Peripheral Sharing Device, Version 4.0), it enables up to four computers of varying security classifications to share a single keyboard, mouse, dual DVI monitors, and speaker set — all with strict hardware-enforced isolation between each connected source. This variant supports DVI interface connectivity without CAC (Common Access Card) reader support.

Multi-layered security is built into every aspect of the CS1144D4: always-on chassis intrusion detection renders the switch inoperable if tampered with, non-reprogrammable firmware eliminates firmware-based attack vectors, and unidirectional data flow ensures no cross-contamination between ports. Keyboard and mouse buffers are automatically purged on port switching, and non-authorised HIDs and video connections are rejected outright. Supports DVI Dual Link resolutions up to 2560 x 1600 and ATEN Video DynaSync™ for seamless display optimisation across sources.
