**This product has reached End-Of-Life status. See link to Its successor product: SECURE 2 PORT MINI-MATRIX SWITCHES**

The K222 is a secure 2-Port/2-Display DVI-I Mini-Matrix Switch.

It allows a single user to share two displays and a single set of keyboard, mouse & audio between two computers that belong to different security classifications while isolating both hosts from each other and from the peripherals that are being shared through it, keeping the data of each computer completely separate.

The Mini Matrix allows full flexibility in assigning keyboard, mouse and monitor to either one of the sources. The user can easily decide which source will be projected on which display, including duplicate and extended display modes.

The K222 is designed to provide the highest possible computer & peripheral isolation as demanded by government agencies, military, financial institutions and similar security sensitive customers. It is built to comply with EAL4+ security requirements and with the latest requirements of the National Information Assurance Partnership (NIAP) Protection Profile PSS Ver 3.0 for peripheral sharing switch devices.

The K222 best suites manager offices and meeting rooms that frequently host multi-participant meetings where two computers need to be simultaneously presented on different monitors or big screen TVs, as wells as, control rooms where often operators are required to integrate information from two isolated sources on two displays in real-time.

 How does it work?

  • Connect two computers and two displays to the Mini Matrix.
  • Computers and peripherals are fully isolated from each other.
  • User can select which source to present on each of the two attached displays. Duplicating and extending a single source is also supported.
  • User can interact with both computers at the same time using a single set of keyboard and mouse.
  • Seamlessly switch between the selected sources by moving the mouse cursor across screen boarders.
  • Audio is switched automatically once control is switched to another source.
  • Simultaneously control and view 2 computers on 2 displays at the same time.
  • Virtual Display Technology (VDT):
    Seamless keyboard, mouse and audio switching between computers once mouse cursor crosses display borders.
  • Work freely without compromising security:
    Display and control classified and non-classified computers without compromising security.
  • Protect against leakage and malicious attacks through USB, keyboard, mouse, video and audio peripherals: 
    Prevent vulnerable peripherals from mediating between computers by ensuring that video, audio and USB data flows in a single direction.
  • Protect against unauthorized peripheral device threats:
    Threats imposed by peripheral devices that should not be connected to a specific peripheral sharing switch port (e.g., a USB mass storage device mistakenly connected to the keyboard port).
  • Protect against authorized but untrusted peripheral device threats:
    Threats imposed by legitimate and authorized peripheral devices (such as a standard USB keyboard) that may be vulnerable to malicious attacks and cause data leakage when switched between sources.
  • Cost effictive solution: 
    More flexible than a KVM, less space consuming than a KM, less expensive than a KVM Combiner.
  • Flexible video projection: 
    Interact with multiple computers and project to multiple connected displays. Duplicate presentor / guest computer display onto a big screen TV.
  • Future-proof: 
    Supports latest keyboards, mice and all Operating Systems.

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