Out-of-Band Firmware Update

February 2026 - Out-of-Band Firmware Update ISO

Use this out-of-band firmware update ISO to update your Secure Malware Analytics Appliance firmware. This method allows you to update firmware without a software release.

Before you begin


Important

We recommend this firmware update for both M5-series and M6-series hardware.

Before starting the firmware update process, ensure you have:

  • A USB device with at least 2GB of storage capacity, but larger drives are recommended since they are more performant and reliable.

  • Access to the appliance's physical console.

  • A USB creation tool (Rufus on Windows, dd on Linux/macOS, or similar) - this is similar to the airgap update process, see those docs for more details.
