ATEN CS1188DP4 (8-Port Secure DisplayPort KVM Switch / NIAP PP4.0 / $981.35) Review
The ATEN CS1188DP4 is an 8-port secure DisplayPort KVM switch built to NIAP PP4.0 requirements, with isolated per-channel video buffers, no hotkey switching, and no general USB hub, priced at $981.35.
The CS1188DP4 is the top of ATEN's CS118xDP4 secure tier, giving an analyst up to eight isolated security domains from one keyboard, mouse, and monitor without weakening the same pushbutton-only, no-hub design used across the smaller CS1182DP4 and CS1184DP4. It's the switch to reach for when a desk genuinely needs to reach that many separate networks. Versus the ATEN CS1184DP4 — half the ports for meaningfully less money, sufficient for a 4-domain desk. Versus the ATEN CS1188DP4C — the same 8-port layout with an added CAC/smart-card reader channel for PKI authentication.

The Right Size for Heavy Multi-Domain Access
It's the switch to reach for when a desk genuinely needs to reach that many separate networks rather than the 2 or 4 channels smaller models offer.
