Secure KVM Switch for Defence Installations
The ATEN CS1144H4C is a 4-port secure KVM switch built to meet PSD PP v 4.0 requirements for defence and intelligence environments. It lets one local user control four computers while sharing a single keyboard, mouse, dual monitors, speakers and CAC reader. NIAP certification confirms isolation and unidirectional data flow between connected sources of differing classification.
Suited for Multi-Domain Secure Workstations
This switch suits operators who must access multiple security domains from one console without risk of data leakage between ports. It is not for buyers who need to share peripherals across more than four computers, nor for setups that require video resolutions beyond 3840 x 2160 at 50 Hz or 60 Hz.
Verify Port Counts and Video Compatibility
Before ordering, confirm that each of the four computers provides the necessary DisplayPort outputs to match the switch’s ten DisplayPort inputs for dual-display operation. Check that your CAC reader and other USB peripherals are compatible with the eleven USB ports provided. Ensure the 3840 x 2160 resolution at 50 Hz or 60 Hz matches your monitors and source hardware.

Questions about this item
Do I need to provide my own DisplayPort cables to connect four computers to the 10 DisplayPort inputs?
Yes, each computer requires two DisplayPort cables for the dual-display setup, so eight cables in total are needed for the four ports.
Can I keep using a standard USB keyboard and mouse instead of the CAC reader on this switch?
The switch provides 11 USB ports for keyboard, mouse and other permitted peripherals; the CAC reader is an additional supported device, not a replacement.
How can I verify the PSD PP v4.0 isolation is active after I connect everything?
The front-panel port LEDs show the active channel; when a port is selected, the NIAP-certified hardware enforces unidirectional data flow and peripheral filtering for that channel only.
