Control access without compromising the security posture of the workstation. The Black Box KVS4-1004HVX is a NIAP 4.0 certified 4-port KVM switch designed for environments where operator isolation, policy compliance, and dependable source switching matter. With support for a single monitor and FlexPort HDMI/DisplayPort connectivity, it gives administrators a practical way to manage multiple systems from one console while maintaining a disciplined access model. This is the kind of KVM chosen for high-trust environments where the cost of a weak link is unacceptable. NIAP 4.0 certification signals a security-focused design approach, making it suitable for deployments that need controlled peripheral sharing across classified, regulated, or otherwise sensitive workspaces. The 4-port layout keeps the footprint efficient while still supporting multiple connected systems, reducing desk clutter and simplifying operator workflows. For procurement teams, the value is in the balance: fewer devices on the desk, tighter control over access, and a configuration built for serious operational requirements rather than commodity switching. If your environment demands secure, single-monitor KVM control with HDMI and DisplayPort flexibility, the KVS4-1004HVX is built for that job.
