HKS100 Secure Isolator: DVI-I Video, Audio & USB.

How to Order

HSL unique security Isolator solution is based on the company's innovative Secure KVM products. The HKS100I isolates Keyboard, DVI-I Video, USB and analog Audio output.

The HKS100I offers highest possible separation between the source computer and the peripheral devices using unidirectional optical data-diodes to prevent any potential leakage between the source and the peripheral equipment.

KVM and video matrixes, shared displays and projectors are all vulnerable to cyber-attacks. Sharing displays, keyboards and mice between computers or video sources from different networks is a weakness point that can be exploited by attackers. Malicious code and information originating from one network can be transferred via the shared peripherals to a different network.

Secure Meeting or control rooms often require the ability to combine sources hav‌ing different classification levels into one display solution. For example, a projector in a meeting room which requires connectivity to an unsupervised guest laptop for presentations or KVM\Video Matrixes in control rooms combining classified information with Internet or television sources. The HKS100I provides the answer to these needs. 

System Diagram

  • Highest security by design:
    designed by an agency to support isolation of large KVM matrix and conference room equipment

  • Hardware Based peripheral protection/isolation
    Absolutely no dependency on firmware or software, unidirectional optical data diodes assuring USB peripherals isolation. Data can flow from devices to host only. No reverse data flow possible by design

  • Peripherals security
    Full USB devices filtering to assure support for keyboard and mouse only

  • All firmware is in ROM (Read Only Memory)

  • Analog Audio Data Diode:
    Assuring that audio out channel would not be abused to send data back to the computer
  • Display Plug & Play (EDID) protection:
    Leakage prevention through patented emulated technology. Signaling attacks prevented by design. DDC/EDID fully functional

  • Active anti tampering 
    Always-on active anti-tampering with 10 years battery. Special holographic tampering evident labels
  • Support for wide range of video standards
    DVI-I dual-link interface can be used for VGA, DVI-D and HDMI as well
  • Tamper Evident Label
    Providing clear visual indication of product was tampered with or opened in any way
