Black Box KVS4-8001HX Review

The Black Box KVS4-8001HX is a 1-port secure HDMI KVM switch with 4K at 30Hz, 2 USB hub ports, isolated video and USB buffers, a tamper-evident enclosure, and a manufacturer-stated NIAP PP4.0 certification.

A secure single-host HDMI unit with isolated video and USB buffers and a tamper-evident enclosure. The certification listed is manufacturer-stated NIAP PP4.0, and the specs note the model is not individually listed on the NIAP list, so check this if procurement needs formal proof. Maximum resolution is 4K at 30Hz, and there are 2 USB hub ports and no audio. The front-panel pushbutton switches inputs. The price is 527.20, down from 558.48. It suits controlled environments, not casual home use.

Formal NIAP Certification for a Single Host

Unlike the NIAP-style designs elsewhere in this catalog, the KVS4-8001HX carries actual NIAP PP4.0 certification, the documentation government procurement often requires, with a tamper-evident enclosure protecting a single secure HDMI host.

Comparison to Alternatives

Against Vertiv's SC920DPH-400, which handles two DisplayPort hosts with NIAP-style isolation, the KVS4-8001HX is single-host but carries the harder-to-find formal NIAP certification HDMI buyers may specifically require. Its DVI-input sibling, the KVS4-8001VX in this same batch, serves the same certification tier for DVI infrastructure.
