Adder AVSC1102 Secure 2-Port USB VGA KVM Switch (EAL4+/Tempest, CAC Support) Review
Adder AVSC1102 secure 2-port USB VGA KVM switch EAL4+ Tempest certified CAC smart card support, government classified network isolation switch, NIAP secure KVM
A push-button switch built for one purpose: let a single operator work on two physically separate, differently classified networks from one VGA monitor without any electrical path ever connecting them. The CAC reader switches with the video, so smart-card login follows whichever network is active.
What EAL4+/Tempest Actually Buys You
Common Criteria EAL4+ certification and Tempest shielding mean this switch has been independently evaluated to prevent data leakage between connected systems — a real security requirement for classified environments, not a marketing label.
CAC Integration
The dedicated smart-card port switches in lockstep with the video and USB peripherals, so a CAC-authenticated session on one network can't accidentally present credentials to the other.
Comparison to Alternatives
For a VGA-based secure switch with two additional ports, the AVSC1104 covers 4 computers with the same certification. Adder also sells the non-CAC AVSV1002, which drops the smart-card reader for sites that don't need it, at a lower price point. Raritan's RSS-1024K is a comparable secure switch supporting DVI/HDMI/VGA/USB/audio at 2 ports if broader video format support matters more than VGA-only simplicity.
