Vertiv SC940DVI-400 (4-Port Secure DVI KVM Switch / NIAP-Style Isolation / $1251.00) Review
Vertiv SC940DVI-400 4-port secure DVI KVM switch NIAP data isolation government
Extends Vertiv's Secure Console isolation architecture to four DVI hosts, letting an operator with legacy DVI infrastructure switch between four separated networks from a single keyboard, mouse and monitor.
Four Isolated DVI Channels
The SC940DVI-400 answers a common government IT problem: legacy DVI equipment that still needs to be air-gapped from other networks. Each of its four channels keeps video and USB buffers isolated per Vertiv's secure design.
Comparison to Alternatives
Where the SC920DPH-400 covers two DisplayPort hosts, the SC940DVI-400 doubles port count but stays on legacy DVI, making it the better pick for older secure facilities that haven't migrated to DisplayPort. It plays a similar role to SmartAVI's SDHN-4D-P but with native DVI rather than DP-to-HDMI conversion.
