Internet connection required to be able to connect to OPSWAT update servers.
If you have installed or if you wish to use the MetaDefender Update Downloader in a restricted environment, you will have to allow access to the following hosts' for engines / databases download:
Note: IP address-based whitelisting on your firewall might fail after some time since OPSWAT uses CDN (Content Delivery Network) to faster delivery updates over the world, and IP address of edge servers might change over time.
Even the OPSWAT update servers host updates for all of the available engines we support, sometimes the custom engines might try to connect to their own cloud for updates, but this can be disabled in firewall and they will be updated just from OPSWAT.
