Avocent Cybex SV220 (2-Port Secure KVM Switch / $546.00) Review

The Avocent Cybex SV220 is a 2-computer NIAP-certified secure KVM switch with DisplayPort video, priced at $546.00.

The Cybex SV line is Vertiv's entry point into certified secure KVM switching, and the SV220 is the smallest of it, just two computers, one channel of certified isolation between them, for a single-user secure desk that only needs to jump between two security domains. It's a scaled-down sibling to the SC740 and SC780 in this catalog, both 4- and 8-computer secure switches, aimed at desks that genuinely only need two machines isolated rather than four or eight.

Entry-Point Secure Switching

At just two computers, the SV220 is the smallest certified secure KVM in this catalog, aimed at analysts or officers who only need to isolate between two networks, not four or eight.

No Audio Channel, Certified Isolation

Like every secure KVM here, audio switching is omitted entirely to remove a common data-exfiltration vector flagged during compliance audits.

Comparison to Alternatives

Versus the Avocent SC740 — that scales the same certified isolation concept to 4 computers, worth it for a busier secure desk. Versus the ATEN CS1944 — that's a non-certified 2-computer switch at a similar price, worth it only where compliance isn't required.
