## Long description

The ATEN 4-Port USB HDMI Dual Display Secure KVM Switch (model CS1144H4) is a PSD PP v4.0 certified peripheral sharing device designed for environments that require strong isolation between networks. It lets a single keyboard, mouse, dual HDMI monitors and speaker set be shared among up to four computers while enforcing hardware-level protections to prevent data leakage. The unit supports 4K Ultra HD (3840 x 2160) video output, uses USB for keyboard and mouse connectivity, and comes in a metal housing with a wide input voltage range for reliable operation.
Advantages
The CS1144H4 provides strict isolation and unidirectional data flow between connected computers and peripherals, configurable device filtration, and dedicated audio filtration to block unauthorized data transfer. It supports manual switching via front-panel pushbuttons and a Remote Port Selector (RPS) to avoid remote or automatic switching methods. The tamper-proof hardware design and PSD PP v4.0 certification ensure compliance with NIAP protection profiles for peripheral sharing devices.
Suitable for
Government and military installations requiring enforced separation of classified networks
Healthcare environments handling patient data across isolated systems
Banking and finance institutions with separate production and secure networks
Any organization that must share peripherals between multiple security domains without risking data leakage
