Give operators access to four systems without compromising separation or control. The StarTech Secure 4-Port Dual-Monitor KVM Switch is designed for secure desktop environments that need fast switching, clear video, and strict protection against unauthorized access. NIAP 4.0 certification and the absence of internal memory or storage support isolated operation, while the dedicated and configurable CAC port enables smart card login for controlled authentication. Anti-tamper switches detect physical intrusion attempts and respond with visual and audible alerts that disable functionality. With support for HDMI or DisplayPort sources and dual 4K 60 Hz monitors, this KVM is built for security-conscious operators who need more screen real estate and higher resolution than a basic switch can provide. Metal housing and U.S. manufacturing reinforce its fit for procurement teams that need durable hardware for regulated, high-trust deployments.
