Keyboard Mouse (KM) switch offered by HSL allows interacting with multiple computers in real-time while maintaining the highest isolation between computers and peripherals. Directly connect separate display(s) to each computer and securely share keyboard, mouse, audio and USB devices through the KM.

Obviate the need for purchasing and installing dedicated, per-computer peripheral sets.

NIAP Common Criteria PP3.0 Certification

HSL KMs qualify to the latest NIAP Common Criteria Protection Profile version 3.0 (PP3.0) certification for peripheral Sharing Switch (PSS) devices.

Securely share peripherals across different security domains

Securely share peripherals between computers that belong to different security classifications levels while keeping the highest possible data separation security.

Prevent information leaks

Obstacle threats derived from sharing and switching of vulnerable, untrusted or unauthorized peripheral devices. Block peripheral exploits, information leaks, eavesdropping, signal transmission, computer malware, hardware and firmware tampering by enforcing multilayered security mechanisms.

Control multi-monitor computers

Support multi-monitor computers with up to 4 displays per computer in duplicate or extended modes (Requires driver installation, currently available only for Windows).

Filter USB Peripherals

Block unauthorized USB devices while allowing secure switching of smart card and biometric authentication devices between computers. Whitelist and blacklist specific USB devices based on VID/PID characteristics.

  • Interact with multiple isolated computers using a single set of keyboard, mouse, audio and USB peripherals.
  • Freeze USB (SM40NU-3, SM80NU-3):
    Assign the USB port to a specific computer while switching the keyboard, video, mouse and audio between other computers. Useful for various scenarios, for instance, when a USB smart card reader  must remain mapped to a certain computer.
  • Smoothly switch between computers (Virtual Display Technology):
    Automatically switch control from one computer to another by dragging the mouse cursor over the computer’s display border. Peripherals switch to the next computer without hav‌ing to press any buttons once the mouse is passing the display border.
  • Avoid typing mistakes:
    Since two-way communication is blocked by the KM security, keyboard lock LEDs do not function. Help users avoid typing mistakes by visually indicating the status of keyboard locks (CAPS-LOCK | NUM LOCK | SCROLL LOCK) on the product’s front facing panel.
  • Support various display layouts:
    Align displays vertically (on top) / Horizontally (along side)…etc. Associate the mouse cursor with each computer based on its respective display position.
