How to Order

The K424F is a secure 4-port KVM combiner switch which allows to simultaneously interact with and present up to four computers from different security classifications on two displays while isolating all coupled hosts from each other and from the peripherals that are being shared through it, keeping the data of each computer completely separate. 

The K424F 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.

In screen duplication mode all (4) incoming sources are presented on the K424F primary display which is duplicated to a second display. This layout is ideal for meeting / control room and big screen TV projection scenarios.

In extended view mode the incoming channel presentention is split between two displays. 

Incoming source channels can be aligned in various view modes (tile/scale/custom/full screen) on the two output displays. For example, when used in Scale mode the active channel will be presented on the primary display while the other (3) channels will be scaled and presented on the secondary display.

Simple switching allows the user to change channel alignment layouts ‘on-the-fly’ with a click of a mouse to instantly fit with any work requirement at all times.

How does it work?

  • Connect up to four computers and two displays to the KVM Combiner.
  • Connect a smartcard/biometric reader to the combiner's DPP secure port to support user authentication across multiple isolated computers.
  • Computers and peripherals are fully isolated from each other.
  • All computer screens are presented simultaneously on the Combiner's primary and secondary display in one of the various view modes (tile/scale/custom/full screen).
  • User can interact with multiple 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.

No need to push any buttons to switch between sources. Take immediate control of any source with a single mouse click without changing to a different display, keyboard or mouse. With cursor navigation switching the user can move from one highly isolated computer system to another by simply moving the mouse cursor across display borders. Audio and keyboard follow the mouse as its cursor crosses the display borders.

  • Simultaneously interact with and present (4) isolated computers on two displays
  • 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.
  • Duplicate & Extend view modes:
    Provide flexible presentation options to fit any meeting / control room use case scenario.
  • Flexible screen layout: 
    Resize source scaling and aspect ratio to create Tile, Scale and Custom display layouts that fit user needs.
  • Native touch screen support: 
    Native touch screen support with all connected computers.
  • Zero quality loss: 
    Real-time view through a pixel-by-pixel video image; no quality loss, latency, reduced colors, dropped frames or artifacts.
  • Biometric/Smart-Card reader support:
    Connect a smartcard/biometric reader to the Combiner's DPP secure port to support user authentication across multiple isolated computers.

  • Future-proof:
    Supports latest keyboards, mice and all Operating Systems.

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