Secure Keyboard, Video, and Mouse operation on up to two or four computers with one or two DisplayPort monitors Keep 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 DisplayPort displays. Certified for NIAP Protection Profile for Peripheral Sharing Device Version 4.0 The Secure KVM Switches are tested and certified under the USA scheme for NIAP Protection Profile 4.0 so you get the best data protection available on the market today. Control the Switch via Front-Panel Buttons Use 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 Security Data 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 Breaches The 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 Emulation The 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 newly 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. Tamperproof Seals Protect Your Devices Built-in tamperproof seals and a long-life internal anti-tamper battery add even more security for your devices.
