4-Port Secure KVM Switch

This Belkin KVM switch lets a single operator control four computers from one keyboard, mouse and DisplayPort monitor. It is built for environments where data must not leak between security enclaves.

NIAP Protection Profile 4.0

The device meets Common Criteria and NIAP Protection Profile for Peripheral Switching Devices version 4.0 requirements. Optical data diodes and embedded peripheral emulation isolate each connected system, while active anti-tamper protection guards against physical and ultrasonic audio attacks.

Four-System Enclave Isolation

The switch comfortably handles four separate security domains with automatic video sensing and internal converters for mixed legacy and modern sources. It runs out when a fifth enclave must be added or when dual-head video output is required.

Questions about this item

Should I pick the 4-port model or look for a different port count?

The F1DN104KVMUNN4 provides exactly four ports, so choose it when you need to control four computers from one console.

What does the NIAP Protection Profile 4.0 rating mean for daily use?

It certifies that the switch meets Common Criteria requirements for isolating peripherals across separate security enclaves.

Does the DisplayPort and USB interface limit the video resolution or peripheral speed I can use?

The switch uses optical data diodes and embedded emulation to share peripherals safely; resolution and speed depend on the connected computers and cables.
