Product Highlights

KVMs becoming a target for cyber attacks as they may be the only possible link to bridge between isolated classified networks and networks open to the internet. Many high security organizations adopting secure KVMs as part of their cyber protection strategy, in some cases this effort is not enough. Second-Generation Secure KVMs sold in the market today have documented vulnerabilities that may cause data leakages between connected computers with different security levels.

HSL’s Secure KVM is the industry’s first 3rd Generation Secure KVM. This product offers the highest possible separation between 4 connected computers. The K20x Secure KVM designed to meet the requirements of organizations that are challenged by the need to provide secret or top-secret network access together with unclassified or internet access.

The K200 series KVM uses unidirectional optical data-diodes to prevent any potential leakage between the highly-isolated peripheral channels. This KVM 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 dual-link DVI and HDMI.

RDC (Remote Desktop Controller) port enables simple interface with HSL's RDC440 controller. Using the K244 with RDC440 users can control and monitor the Secure KVM remotely and enjoying color LCD with programmeable network/computer names. For more information see RDC440 page.

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.
