Our take on the Black Box SS4P-DH-DP-U 4 Port Secure SH DP USB KVM Switch

The Black Box SS4P-DH-DP-U is a 4-port secure KVM switch that lets one keyboard, mouse and DisplayPort monitor control four computers while keeping each host isolated. It is built for government, defense and financial desks where switching between classified and unclassified systems is routine. Compared with ordinary KVM switches, it adds strict port-to-port isolation and tamper-resistant firmware, but it is bulkier, costs far more and offers no USB peripheral sharing beyond the protected ports. Buyers choose it for compliance, not convenience.

Questions and answers

What does the SS4P-DH-DP-U do?
It switches one DisplayPort monitor, keyboard and mouse between four computers while keeping the computers electrically isolated from each other.
Is it different from a regular 4-port KVM switch?
Yes. It is a secure KVM built for isolated networks, with tamper protection and no data path between ports. A regular KVM is cheaper but not designed for classified or regulated environments.
Does it support audio or USB drives?
No. Secure models restrict peripheral sharing to the protected keyboard and mouse ports, so audio and storage devices are not passed between hosts.
What monitor connection does it use?
It uses DisplayPort for the console monitor and each connected computer. Check that your hosts and monitor have DisplayPort outputs and inputs.
Who should buy it?
Buy it if policy or contract requires an isolated multi-system console. For home or small-office switching, a standard KVM is simpler and far less expensive.
