ATEN CS1184H4 4-Port Secure KVM Switch 3840x2160 50 60 Hz

Secure KVM for defence and intelligence

The ATEN CS1184H4 is a four-port secure KVM switch built to meet the stringent requirements of defence and intelligence installations. It allows a single local user to control four computers of varying security classifications using one keyboard, mouse, monitor and speaker set. The unit is compliant with the PSD PP v4.0 Protection Profile certified by the National Information Assurance Partnership. Hardware-enforced isolation and unidirectional data flow prevent unauthorised data leakage between connected sources.

Suited for high-security multi-domain operations

This switch suits operators who must share peripherals across isolated networks while maintaining strict data separation. Configurable device filtration and restricted peripheral connectivity ensure only authorised endpoints interact with each connected computer. It is not for environments that do not require NIAP-certified peripheral sharing protection. Buyers needing simple desktop switching without mandated security profiles should look at standard KVM models. Organisations requiring more than four connected computers will need a different solution.

3840x2160 at 50/60 Hz with rack mounting

The switch supports a maximum video resolution of 3840x2160 at 50 Hz and 60 Hz, providing clear visual output for the connected display. Five HDMI ports and six USB ports handle video, keyboard, mouse and audio connections for the four computers and the local console. Rack-mountable construction allows integration into standard server cabinets. Headroom is defined by the four-computer limit and the single local user console; additional sources or users exceed the switch capacity.
