When data separation is non-negotiable, this secure 4-port KVM switch gives operators controlled access without compromising system isolation. The StarTech CK4-P204 is designed for environments that require NIAP 4.0 certification, physical tamper detection, and no internal memory or storage. That combination helps reduce the risk of data leakage across connected systems. Support for four DisplayPort desktops or servers and two 4K 30 Hz monitors gives users the screen space needed for secure monitoring, analysis, and administrative work. Status LEDs simplify port awareness at the console, while the metal housing adds the durability expected in enterprise deployments. This is not a general-purpose KVM. It is built for security-first operations where policy, auditability, and physical control are part of the purchase decision. Anti-tamper switches detect intrusion attempts and disable functionality, adding a layer of protection that cheaper desktop switches do not provide. Made in the USA, the CK4-P204 is a strong choice for government, defense, and other sensitive environments that need a compact desktop KVM with strict isolation characteristics.
