4-Port KVM Switch, DisplayPort, Is Ideal for Applications That Demand Secure Networks This DisplayPort KVM switch with 4K is recommended for any government, military, financial 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. The single-monitor switch supports crystal-clear UHD video resolutions up to 3840 x 2160 (4K x 2K) at 30 Hz. NIAP PP3.0 Certified to Meet Today's Top Information Assurance Standards 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 3.0. 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. Top-of-the-Line Security Features Keep Your Data Safe Special protection prevents re-programming or re-reading 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. Anti-Tampering Protection Prevents Physical Breeches 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. Maintains Constant Keyboard and Mouse Emulation for Smooth No-Delay Switching Full USB device filtering ensures support for keyboard and mouse only. 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. TAA-Compliant for GSA Schedule Purchases The B002-DP1A4 is compliant with the Federal Trade Agreements Act (TAA), which makes it eligible for GSA (General Services Administration) Schedule and other federal procurement contracts.
