Belkin 4-Port Dual Head Modular Secure KVM Switch
Base Unit PP4.0 W/ Remote

The Belkin Modular Secure KVM series packs the latest Common Criteria and NIAP Protection Profile version 4.0 design requirements in the most compact form factor available. An included remote control and innovative mount options allow administrators to craft operator stations to meet security requirements while decluttering the desk. A suite of purpose-built cables provides universal video support, allowing any computer to be interfaced with any monitor on any channel of the secure KVM while accommodating most generations of video standards. Optical data diodes and embedded peripheral emulation allow operators to safely share peripherals across multiple security enclaves without exposing potential vectors for attack. The US-manufactured and TAA-compliant secure KVM series are ideal for use in IT environments that demand rigorous cybersecurity provisions-including government, military, and healthcare applications.
