ATEN TECHNOLOGIES CS1148DP4 8-Port USB DisplayPort Dual Display Secure KVM Switch PP 4.0

Secure 8-Port KVM for Dual Display Workstations

The ATEN CS1148DP4 is an 8-port USB DisplayPort KVM switch built for operators who must control eight separate computers from one dual-monitor console. It targets secure environments such as government, defence or financial desks where data separation between connected systems is mandatory. The switch isolates each port at the hardware level to prevent leakage between classified and unclassified networks.

PSD PP v4.0 Compliance

The single specification that determines suitability is PSD PP version 4.0 compliance, which certifies the device against the Protection Profile for Peripheral Sharing Devices. This certification guarantees hardware-enforced isolation of video, USB, audio and keyboard/mouse channels for every connected computer. Buyers who do not require this certified assurance should select a standard KVM instead.

Sustained Isolation Under Continuous Switching

Under sustained load the switch maintains certified channel isolation during repeated port changes and long-duration sessions without degrading the security boundary. Video signals remain electrically separated at all times, preventing frame-buffer residue or EDID leakage between ports. USB peripheral emulation stays active on the focused port while all other ports remain logically disconnected, ensuring consistent protection during continuous operation.
