Vertiv Cybex SC800 Secure (SC820DPH-400) (8 Computers / DisplayPort+HDMI / NIAP-Certified Secure KVM / $876.75) Review
The Vertiv Cybex SC800 Secure SC820DPH-400 is an 8-port NIAP PP 3.0 certified secure KVM switch with DisplayPort and HDMI video up to 4K@30Hz, priced at $876.75.
It's the DisplayPort/HDMI counterpart to the SC840DVI-400 in the same certified line, and actually cheaper - reflecting that DP/HDMI switching silicon has become less expensive than legacy DVI paths at the volumes Vertiv now ships.
Modern Video on a Certified Switch
Newer server and workstation hardware has largely moved off DVI, and the SC820DPH-400 lets a certified secure desk keep pace with 4K DisplayPort/HDMI outputs instead of forcing DVI adapters onto every connected machine.
Lower Cost Than the DVI Sibling
At $876.75 versus $1,050.75 for the SC840DVI-400, this is a case where the newer video standard costs less to implement at scale, not more - worth checking before assuming DVI is the cheaper choice.
Comparison to Alternatives
Versus the Vertiv Cybex SC840DVI-400 - functionally identical certification and port count, choose based on whether connected machines output DVI or DisplayPort/HDMI. Versus the Vertiv SwitchView 300 Series (SV340DPH-400) - similar video standard but only 4 ports and no NIAP certification. Versus the Adder ADDERView Multi-Viewer (CCS-MV4224) - that's built for simultaneous multi-screen viewing rather than certified single-port secure switching.
