Bring secure, controlled access to two DisplayPort systems without exposing them to unnecessary risk. The StarTech CK4-P102C is designed for environments that require strong separation between connected computers, with NIAP 4.0 certification, no internal memory or storage, and a secure desktop architecture that helps prevent data leakage. Support for a 4K 30 Hz monitor gives operators clear visibility for administrative tasks and system monitoring. A dedicated and configurable Common Access Card port supports smart card login, aligning the switch with regulated access workflows. Status LEDs simplify port awareness, while anti-tamper switches detect physical intrusion attempts and disable functionality with visual and audible alerts. The metal housing adds durability for desktop use, and U.S. manufacturing supports procurement requirements where origin matters. For teams that need a compact secure KVM for two systems, this model delivers the control and assurance expected in sensitive environments.
