Raritan SS4-104-DUAL (4-Port Secure Dual-Monitor KVM Switch / NIAP PP4.0 / $1328.19) Review
The Raritan SS4-104-DUAL is a 4-port secure dual-monitor KVM switch built to NIAP PP4.0 requirements, with selectable DisplayPort/HDMI/VGA video on two isolated heads per channel and front-panel-only pushbutton switching, priced at $1328.19.
The SS4-104-DUAL takes the same NIAP PP4.0 isolation model as the RSS4-104 and extends it to two monitors per connected computer, which is the more realistic setup for classified analyst workstations where a second screen for reference material or a secondary application is standard practice. Both video buffers per channel remain fully isolated, so the security posture doesn't weaken just because a second head was added. Versus the Raritan RSS4-104 — the single-head sibling, meaningfully cheaper if only one monitor is needed. Versus the ATEN CS1188DP4 — an 8-port secure DisplayPort alternative for larger single-head deployments rather than dual-monitor ones.

Expert rating8.7 / 10
The dual-monitor answer for secure analyst workstations, with the same rigorous per-channel isolation as Raritan's single-head model.
Best for
- Classified analyst workstations needing two isolated monitors per source
- Government facilities requiring NIAP PP4.0 dual-head secure switching
- Multi-domain setups where a single monitor is genuinely insufficient
Not for
- Single-monitor secure desks (the RSS4-104 is cheaper)
- Commercial desks with no certification requirement
- Deployments needing more than 4 secure ports
