Scale secure console access across eight computers without giving up control over the workstation boundary. The CS1148D4 is built for USB DVI dual-display environments, allowing operators to move between connected systems from one console while maintaining the disciplined access model expected in sensitive infrastructure. Its PP4.0 secure KVM architecture is suited to high-assurance deployments where peripheral sharing must be tightly governed. That makes it a strong fit for command centers, security operations, and regulated enterprise spaces where the KVM is part of the control plane, not just a convenience device. With eight ports, this model serves teams that need broader coverage than a 2-port switch can provide, while still keeping the user experience focused and predictable. It is the right tier when the cost of a weaker access model is higher than the price difference between basic and secure switching.
