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

The K502 is a secure 2-port, small-form-factor, DisplayPort KVM Switch.

It allows users to share peripherals - keyboard, video, mouse and audio - between two computers from different security classifications 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 K502 combines low-cost with high-security built by design 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.

With the K502 users can save valuable desk area in space-restricted environments and increase productivity by interacting with two computers using a single set of keyboard, video, mouse and audio.

How does it work?

  • Connect two computers and a single display to the KVM.
  • Computers and peripherals are fully isolated from each other.
  • User can interact with multiple computers using a single set of keyboard and mouse.
  • Switch between the selected sources by channel-select push buttons and/or keyboard shortcuts.
  • Audio is switched automatically once control is switched to another source.


  • Interact with two isolated computers using a single set of keyboard, video, mouse and audio peripherals.
  • 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.
  • 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.

  • AUX channel protection:
    Leakage prevention through patented AUX channel firewall technology. Signaling attacks prevented by design. EDID is fully functional.
  • Future-proof: 
    Supports latest keyboards, mice and all Operating Systems.
  • Highest security by design: Common Criteria EAL 4+ approved, compatible with NIAP security requirements.
