Internet connection required to be able to connect to OPSWAT update servers.
If you have installed or plan to use the MetaDefender Update Downloader in a restricted environment, you must allow access to the following hosts for engine and database downloads:
Note: IP address-based allowlisting on your firewall may fail over time because OPSWAT uses CDN (AWS Cloudfront) to accelerate global update delivery, and the IP address of edge servers may change periodically.
Depending on your location, connections to OPSWAT's cloud-based servers may be forwarded to specific AWS Cloudfront edge locations, each assigned its own unique IP address ranges. You may also need to allow the corresponding AWS Cloudfront IP address ranges by referring to https://ip-ranges.amazonaws.com/ip-ranges.json
Although OPSWAT update servers host updates for all supported engines, some custom engines may attempt to connect to their own cloud for updates. However, this can be blocked at the firewall, ensuring that updates are retrieved exclusively from OPSWAT.
