NIAP-certified KVM lets you access multiple computers from a single console while protecting data from accidental or unauthorized transfer between them. This four-port KVM switch is recommended for any government, military, finance, education or healthcare environment where tight security of sensitive data is of utmost importance in a world of constantly changing cyberthreats. Each KVM port is an electronically isolated channel, making it impossible for data to be transferred between connected computers through the KVM, even when the computers are of different security levels. The single-monitor switch supports crystal-clear Ultra HD video resolutions up to 3840 x 2160 (4K x 2K) at 30 Hz. This KVM switch is certified by NIAP (National Information Assurance Partnership), which is operated by the National Security Agency (NSA), to the latest Common Criteria Protection Profile for Peripheral Sharing Switches Version 4.0. Discrete processing paths to each connected system prevent data leakage, transfer and crosstalk between adjacent ports. Peripheral isolation enables data to flow from device to host only. Special protection prevents re-programming of firmware, so the switch’s KVM logic remains unaltered. The keyboard buffer clears automatically after data transmission, ensuring no information is left stored. Plus, you can only access connected computers via buttons on the switch’s panel. Other port-switching methods, such as on-screen display (OSD) and hotkey commands, have been excluded to further ensure data integrity. The Common Access Card port supports smart cards, scanners and biometric readers, including fingerprint readers, to bolster security. You may assign and register specific peripherals to the CAC port, providing a secure connection for user authentication. If the housing is opened, internal anti-tamper switches will disable the unit, causing it to become inoperable and the front-panel LEDs to flash repeatedly. Seals on the enclosure will provide visual evidence of tampering. Full USB device filtering ensures support for keyboard and mouse only — no flash drives allowed. This KVM switch also supports secure video emulation and EDID learning, which prevents unwanted data from transmitting through the DDC lines. Both keyboard/mouse and video emulation controllers restrict discovery of newly connected peripherals or monitors during switching operations, shielding your computers from potential vulnerabilities. Tripp Lite’s P783-006-U and P783-010-U KVM cable kits (sold separately) help eliminate unnecessary clutter and save you money by combining cables into one convenient kit. These cables comply with HDCP 2.2 and DisplayPort 1.2 standards and support USB 2.0 speeds up to 480 Mbps. The B002-DP1AC4-N4 is compliant with the Federal Trade Agreements Act (TAA), which makes it eligible for GSA (General Services Administration) Schedule and other federal procurement contracts.
