  • FI11P-3 - Secure 1-Port DisplayPort KVM Isolator, PP 3.0


The secure isolator prevents vulnerable peripherals from mediating between compromised and secure computers by ensuring that video, audio and USB data flows in a single direction.

By preventing host-to-peripheral direct access the secure isolator eliminates data leakage.

The secure isolator is designed to provide the highest possible computer & peripheral isolation as demanded by government agencies, military, financial institutions and similar security sensitive customers.

The isolator perfectly suites scenarios where vulnerable peripherals or computers may impose a security threat. For example, in a secure meeting room, when an unsupervised (non-secure) guest laptop has to be connected to a projector which is shared with a classified computer. By isolating the classified computer from the projector the secure isolator protects the classified computer from being infected by the guest computer compromising any projector’s vulnerability.

Additionally, by allowing sound to travel only in one direction from the PC to the speaker, the isolator protects against eavesdropping attempts hence prevent intruders from compromising a computer's security and re-tasking the audio line-in (headset/speaker) into a microphone line.

How does it work?

  • Connect the computer's keyboard, mouse, display and audio ports to the isolator.
  • Connect the isolator to the keyboard, mouse, display and audio peripherals.
  • Computer and peripherals are fully isolated from each other.
  • User can securely use the peripherals.
  • Protect against leakage and malicious attacks through USB, keyboard, mouse, video and audio peripherals.
  • Prevent compromised peripherals from infecting computers: 
    Isolate computers in meeting/control rooms from vulnerable peripherals that are shared between multiple computers.
  • Help secure matrix environments: 
    Protect classified computers in matrix-environments from shared-peripheral-threats originating from guest laptops or internet-access computers that connect to the same matrix. Securely join a low-security source to a matrix by connecting it through an isolator which assures that the matrix security is not compromised.
  • Work freely without compromising security:
    Display and control classified and non-classified computers without compromising security.
  • Protect against unauthorized peripheral device threats:
    Threats imposed by peripheral devices that should not be connected to a specific peripheral 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 computer display) that may be vulnerable to malicious attacks and cause data leakage when shared between sources.
  • Small form factor: weighing as little as 0.6 lbs. and with a width of 5.8 Inches, it occupies minimum desktop space.

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