The StarTech CK4-HP204C is a NIAP 4.0-certified secure KVM switch for controlling up to four computers with one keyboard and mouse and two 4K 60Hz displays. It suits government, enterprise, and IT environments that need secure multi-system access, CAC support, and physical tamper protection.
Recommended For
- Security operators who need to switch one keyboard, mouse, and two monitors among as many as four separate systems while maintaining NIAP Protection Profile 4.0 isolation between them.
- Government, defense, or intelligence teams managing sensitive or classified systems from a shared dual-monitor workstation, where physical system separation and tamper detection are part of the workflow.
- IT administrators and users who sign in to multiple connected systems with a CAC or compatible smart-card reader and want to switch that authentication workflow alongside the workstation.
- Operators who use a fixed desktop setup to work across multiple HDMI- or DisplayPort-equipped desktops, workstations, or servers, and are comfortable selecting systems with front-panel buttons.
Real-World Use Scenarios
- At a government or defense workstation, an operator switches between separate secure systems from one desk setup; the KVM is designed to keep the connected systems isolated while sharing the keyboard, mouse, and two monitors.
- When workstations require smart-card sign-in, an operator can use the KVM’s CAC connection to present a compatible card to the selected computer instead of plugging a reader into each machine.
- An IT or security team managing several workstations can use one console for up to four connected computers, selecting the system they need without dedicating a separate keyboard, mouse, and monitor pair to each desk position.
- For tasks that benefit from two displays—such as reviewing information across separate windows—an operator can keep both monitors at the shared console and switch them with the selected computer.
- In a controlled-access workspace, staff can check the unit’s tamper alerts and indicators as part of handling the shared console; an intrusion alert disables the KVM rather than allowing normal continued use.
