  • Control multiple computers with a single set of peripherals while isolating data paths between systems and ensuring no data is ever stored

    Operate multiple secure systems from a single workstation with the NIAP-Certified KVM switch, delivering uncompromising security, enterprise-grade performance, and seamless control over up to four computers with two 4K 30Hz HDMI displays.

    NIAP Certified Multi-System Control

    Manage up to four DisplayPort-enabled desktops, workstations, or servers from one mouse, keyboard, and two 4K 30Hz HDMI monitors. Status LEDs on the console ports, CAC port, and port selection indicators provide instant visual feedback, while NIAP certification ensures complete system isolation to prevent any data transfer or leakage between connected systems. Integrated anti-tamper switches provide protection from the moment the unit leaves the factory, so any intrusion attempt, whether in storage, transit, or operation, will permanently disable the KVM and trigger clear visual and audible alerts. This makes it ideal for safeguarding operations across security domains or ensuring compliance with strict regulatory requirements.

    This secure KVM complies with the following protection profiles and modules:

    • Protection Profile for Peripheral Sharing Device (PSD), Version 4.0
    • PP-Module for Analog Audio Output Devices, Version 1.0
    • PP-Module for User Authentication Devices, Version 1.0
    • PP-Module for Keyboard/Mouse Devices, Version 1.0
    • PP-Module for Video/Display Devices, Version 1.0

    Built-In CAC Access and Tamper Protection

    A dedicated and configurable Common Access Card port enables secure smart card logins across all connected systems without the need to attach readers to each machine. The advanced Tamper Protection System uses anti-tamper switches to detect physical intrusion attempts, immediately disabling all functionality and triggering visual and audible alerts, while a tamper-evident seal provides clear indication of unauthorized physical access.

    Enterprise-Grade Security and Reliability

    Engineered for IT professionals, our secure KVM switches are built in the USA, NIAP certified, rigorously tested in our Innovation Lab, and trusted by government, military, and enterprise security teams worldwide. Built for environments handling sensitive or classified data, they combine high-assurance security with the dependable performance required for mission-critical operations.
