SDPN-4S: Ultra-Secure KVM SwitchingMade In America

The SDVN-4S is a 4-port, single-head DisplayPort Secure KVM switch with support for 4K (3840×2160 @ 30Hz) resolution video.The SDPN-4S-P allows users to control KVM (Keyboard, Video and Mouse) operation on up to four computers with DisplayPort monitors. It features mechanical, electrical and optical signal isolation to prevent hacking and data leakage in environments where security is paramount.

With the SDPN-4S, all data relays are controlled by inverted signals, shielding connections from outside intrusion by forcing them each to work one at a time. Each port uses its own isolated data channel and each unit features non-reprogrammable ROM to better protect the switch's functions. Better yet, the SDPN-4S offers the highest security when accessing classified and public networks over the internet through these isolated connections. By isolating connections between networks, the SDPN-4S ensures no data is leaked between secure ports and the outside world.

The SDPN-4S has clearly marked front-panel buttons for controlling the device, so securely switching between sources is always simple. For high-grade secure switching made easy, look no further than the SDPN-4S.
