Software and Hardware updates for Airgap network

How can I get access to update files for hardware/firmware, etc that can be downloaded from your site and then transferred to my secure network which never touches the real world internet?

Good question, haven’t been asked that one before. Perhaps you could download the files from a home computer, the same one you used to post this forum note for example. Worst case we can ship you a USB drive loaded with all the files, we’d ask you to cover the shipping is all.
