Maintain strict separation across four connected systems with a secure KVM designed for high-trust environments. The Vertiv Avocent/Cybex SC Universal DP/H Secure KVM Switch supports single-display operation and CAC authentication, helping teams control access without adding complexity at the desk. Built for environments where data handling rules are non-negotiable, this 4-port model is a strong fit for defense, government, utilities, and other regulated operations. The secure switching architecture helps reduce the risk of cross-system exposure while keeping operators productive on a single console. Compared with basic KVM switches, this model is purpose-built for security-sensitive workflows. It is the right choice when the requirement is not just to connect systems, but to preserve separation, enforce access discipline, and support compliance-driven deployments. For teams standardizing secure operator stations, that distinction matters.
