Why are some modules not appearing in my MetaDefender Core inventory?

If your inventory does not include all of the modules that are listed as part of your MetaDefender Core package license, this is likely indicative that the system is deployed offline (in a restricted environment) and is unable to connect to the necessary OPSWAT hosts for initial module activation and regular updates.

For offline environments, the Core deployment requires an import YAML license into the activation tab for the engines as well as engines download using MetaDefender Update Downloader to be successfully deployed.

If the issue is network related, please keep in mind that, in an online environment where MetaDefender Core is configured to download module and scan engine update packages directly from an OPSWAT update server source, using a gigabit network speed (125MB/sec) is highly recommended to avoid potential network related issues during file downloads. The same is true for initial activation downloads.

At the very least, the requirement is a network speed of 100Mbps (12.5MB/sec).
