K202D Secure KVM Switch: 2-Port, DVI-D.

How to Order

The K202D is a secure 2-port, small-form-factor, DVI-D KVM Switch.

It allows users to share peripherals - keyboard, mouse and monitor - between two different security-level networks/computers.

The K202D combines low-cost with high-security and targets to reduce desktop clutter and increase productivity. It supports DVI-D video.

The K202D is built by design to provide highest possible isolation between two connected computers. It meets the requirements of companies challenged by the need to provide both secret and top-secret network access together with unclassified or Internet access.

The K202D is a perfect fit for high-security organizations such as government agencies, military and financial institutions, and any other organization that handles sensitive and confidential information.

The products are fully compatible with EAL4+ and NIAP security requirements.

  • Small form factor: weighing as little as 1.5 lbs. and with a width of 5.4 Inches, it occupies minimum desktop space

  • Low cost: attractively priced and yet not compromising product's high-quality and security

  • Highest security by design: Common Criteria EAL 4+ approved, compatible with NIAP security requirements

  • Hardware-based peripherals isolation: no dependency on firmware or software; all firmware on ROM (Read Only Memory); no keyboard buffering or memory

  • Unidirectional Optical Data Diodes: assuring USB peripherals isolation; data can flow from devices to host only

  • Display plug & play (DDC) protection: leakage prevention through patented emulated technology; signaling attacks prevented by design; DDC/EDID fully functional

  • Peripherals Security: full USB device filtering to assure support for keyboard and mouse only
