To update the software on your ThreatBlockr 1.0, first log in to the Bandura Cyber Global Management Center and select Software > ThreatBlockr in the left menu. On the ThreatBlockr Software page you will see the latest release, 3.73.003920, at the top of the page. Click on the download icon at the very right side of the row to download the software to your local drive.
Once you have the software file downloaded, you'll need to log into the device UI. In the device UI, select Update Software in the left menu. Click the browse button to find the file, then after the file uploads click on the Install button.
Note that the ThreatBlockr will reboot during the software update process, and it will move into Bypass mode during the reboot. Most customers notice a brief network disruption when it moves into bypass mode and when it comes back out of bypass mode (a few pings on each end). We have had some customers report their device disrupts traffic during the entire update process, so we recommend doing the update at a time when network traffic is minimal.
