About USB DataDiode


Lawyers, forensics investigators, and corporate IT staff who want to transfer data from an unsecured network to a secured network rely upon the CRU® WiebeTech® USB DataDiode™ to protect data.


In network environments with secure (classified) networks, rules exist to keep the secure network isolated from less secure (unclassified) networks. USB DataDiode ensures connection to only one host at a time, so that secure and non-secure networks are never connected to each other.


USB DataDiode is connected to two hosts with two USB cables. It’s easy to select the desired host with the flip of a switch.


Prepare data to copy from the unsecure host with full read/write access to the USB device connected to USB DataDiode.


Press the switch on USB DataDiode to terminate the connection with the unsecure host, and begin a connection with the secure host.


The secure host now can copy data, but cannot write any data back to the USB device, as this host has a read-only connection.


Use the included Forensic Software Utility to display information about connected devices and enable you to save the information in common text formats when in Read-Only mode.


Additional features:


  • Compact design
  • Plug-and-use operation
