The Ultimate Secure KVM Solution
KVM becoming a target for networks leakage attacks. Second-Generation Secure KVMs have documented vulnerabilities that may cause data leakages between hosts having different security levels.

HSL’s K244 Secure KVM Switch provides the highest possible isolation between four connected dual-head computers. This Third- eneration KVM was designed to meet the requirements of organizations challenged by the need to provide secret or top-secret network access together with unclassified or internet access.

The K2xx series KVM uses unidirectional optical datadiodes to prevent any potential leakage between the highly isolated peripheral channels. K200 can also be used to securely filter and lock USB ports preventing data export / import through mass-storage devices by hardware.

The K244 drives two independent user displays and supports four isolated computers each having two video output with video interface from VGA to duallink DVI and HDMI.
The K244E model provides a dedicated peripheral port to securely support bi-directional devices such as smart-card reader, biometric device or touch screen.
Remote Desktop Controller RDC) option enables comfortable remote control of all KVM functions through a rotary switch and a graphic LCD.

Features:
• Dual-head support
• Support four computers each one two displays. Support any resolution. Can drive VGA, HDMI single-link and dual-link DVI. Unidirectional optical data diodes
• Assuring USB peripherals isolation. Data can flow from devices to host only. No reverse data flow possible by design.
Smart-Card reader support
• Special secured port for smart-card or biometric reader with patented Freeze function to support user authentication across multiple isolated networks [K244E only].
Future-proof
• Supports widest variety of peripherals and computers. Supports the widest range of video formats from VGA, single-link to 2560x1600 dual-link. DVI and HDMI. Supports the latest keyboards, mice and card readers and all Operating Systems.
Highest security by design
• Designed by an agency to support isolation between national security networks and internet. Designed to comply with Common Criteria EAL 5. Derivative of a TEMPEST
product used in NATO nuclear submarines. Hardware Based peripheral protection/isolation
• Absolutely no dependency on firmware or software. All firmware is in ROM (Read Only Memory). No keyboard buffering or memory. More than 60dB isolation between channels. Display Plug & Play (DDC) protection
• Leakage prevention through patented emulated technology.
Signaling attacks prevented by design.
Always-on Active Anti-tampering
• Enclosure tempering sensed by multiple sensors. Battery powered anti-tampering circuitry prevents normal KVM operation.
