Features:4-Port, Single-Monitor, DVI-ICertified for NIAP Protection Profile for Peripheral Sharing Device Version 4.0Single-Monitor DVI-I video interfaceMade in the USATAA CompliantTested and certified under the USA schemeExternal power supplyKeep your sensitive data safe in defense applications, secure control rooms, corporate communications, server operations, educational administrations, medical facilities, banking networks, insurance data centers, transit management, industrial operations, intelligence communications, and more. This Secure KVM Switch features mechanical, electrical, and optical signal isolation to prevent hacking and data leakage in environments where security is paramount. Use the switch to control KVM (Keyboard, Video, and Mouse) operation on up to two or four computers with one or two DVI-I displays.Certified for NIAP Protection Profile for Peripheral Sharing Device Version 4.0The Secure KVM Switches are tested and certified under the USA scheme for NIAP Protection Profile 4.0.Control the Switch via Front-Panel ButtonsUse the clearly marked front-panel buttons for controlling the device, so securely switching between sources is always simple.Isolated Data Channels and Non-Reprogrammable ROM Ensure Maximum SecurityData relays work one at a time to shield connections from outside intrusion. Inverted signals control the data relays. Each port uses its own isolated data channel and each unit features non-reprogrammable ROM to better protect the switch's functions. There is no data leakage between ports. Would-be hackers can never gain access to your sensitive data by compromising the switch's ROM.Protects from Internet Data BreachesThe switch offers the highest security when accessing classified and public networks over the internet through isolated connections. By isolating connections between networks, no data is leaked between secure ports and the outside world.Secure EDID Learn and Video EmulationThe Secure KVM emulates (simulates) the presence of a keyboard and mouse for every attached computer through a USB cable. Both selected and non-selected computers maintain a constant connection with the unit's keyboard-mouse emulation controllers, allowing for ultra-fast switching and restricting the discovery of connected peripherals during switching operations. Emulation of keyboard and mouse also prevents the direct connection between the peripherals and the connected computers, shielding systems from potential vulnerabilities.
