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 allowlisting on your firewall might fail after some time since OPSWAT uses CDN (AWS Cloudfront) to faster delivery updates over the world, and IP address of edge servers might change over time.
Depending on your location, connections with OPSWAT cloud-based servers be forwarded to specific AWS Cloudfront's edge locations, each is assigned with its own unique IP address ranges. You might also need to allow correct AWS Cloudfront's corresponding IP address ranges by referring to https://ip-ranges.amazonaws.com/ip-ranges.json
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.
