Adder AVSD1004 Secure 4-Port USB DVI-I KVM Switch (EAL4+) Review

Adder AVSD1004 secure 4-port USB DVI-I KVM switch EAL4+ certified, government classified 4-network isolation switch, digital video secure KVM desk

The 4-network version of the AVSD1002, giving a certified secure desk digital-video access to four separate classified networks instead of two, without giving up the same evaluated isolation guarantees.

Four Digital Networks, One Certified Switch

Analyst desks running DVI-equipped systems across four separate classification levels get the same hardware isolation as the 2-port AVSD1002, just scaled up.

Fits Modern Workstation Refreshes

As agencies replace aging VGA-era hardware, this model lets a 4-network desk modernize its video path without dropping down to an older certified switch generation.

Comparison to Alternatives

For only 2 networks, the AVSD1002 is the cheaper equivalent. The VGA-based AVSC1104 and AVSV1004 remain options for facilities not yet moved to DVI. Raritan's RSS-104C4K adds HDMI/VGA/audio flexibility on top of DVI at the same 4-port count, at a materially different price point and feature set.
