Avocent SC780 (8 Computers / Dual Monitor Secure KVM Switch) Review

The Avocent SC780 is an 8-computer, dual-monitor secure KVM switch with NIAP-certified channel isolation, the higher port-count sibling of the SC740 in Vertiv's SC700 series.

Same security architecture as the SC740, just doubled to 8 computers, which is the natural upgrade path for a secure operations desk that's outgrown a 4-machine switch but still needs certified isolation rather than a general-purpose unit. It's a more direct fit for larger secure NOCs than the Adder AV4PRO, since the AV4PRO's cascade-to-8 approach isn't purpose-built for the certified multi-domain isolation this series exists for.

8-Computer Secure Scaling

Doubling the SC740's port count while keeping the same certified isolation architecture means larger secure desks don't have to trade security tier for capacity.

Dual Monitor Across All 8 Sources

Both monitors switch together to whichever of the eight computers is active, keeping a consistent extended-desktop layout across every source.

Comparison to Alternatives

Versus the Avocent SC740 — that's the same architecture at 4 computers, worth it for smaller secure desks that don't need 8 ports. Versus the Adder AV4PRO — that also scales to 8 computers via cascading but lacks NIAP-style certification, worth it only where compliance isn't a requirement.
