Bring four systems under control from a single HDMI workstation without compromising the separation security teams depend on. The ATEN CS1184D4C secure KVM is built for environments where access must be tightly governed, combining USB, HDMI, and CAC support in a four-port design. Compared with standard KVMs, this secure model is intended for high-trust deployments where endpoint isolation matters as much as operator convenience. It gives users a single console for efficient switching while supporting smart card authentication through CAC, helping align workstation access with stricter policy requirements. For command centers, regulated operations, and sensitive infrastructure rooms, the CS1184D4C offers a practical balance of control and usability. The four-port layout reduces desk clutter, simplifies operator workflows, and supports a more disciplined access model than lower-tier alternatives. When the cost of a mistake is high, that extra layer of control is the point.
