Raritan RSS4-104 (4-Port Secure KVM Switch / NIAP PP4.0 / $994.95) Review
The Raritan RSS4-104 is a 4-port secure KVM switch built to NIAP PP4.0 requirements, with selectable DisplayPort/HDMI/VGA video, isolated per-channel data paths, and front-panel-only pushbutton switching, priced at $994.95.
Raritan's RSS4 line is the newer generation of its Secure Switch products, built for government and classified environments where each connected computer needs its own physically isolated video and keyboard/mouse path with no shared buffer that could leak data between security domains. There's deliberately no hotkey switching and no general-purpose USB hub — both are common attack surfaces in secure KVM design, so Raritan strips them out in favor of a simple front-panel button per channel. Versus the Raritan RSS-1044K already in this catalog — that's the prior-generation 4-port secure switch, this RSS4-104 is the newer platform. Versus the ATEN CS1184DP4 — a comparable 4-port secure DisplayPort switch from a different vendor, worth comparing on certification scope and price.
