Firewalls help protect your network by deciding what traffic gets in or out. They can block everything, allow everything, or filter based on specific rules—like port, location, domain, or IP.

To keep WeTransfer running smoothly, your firewall needs to allow traffic to and from certain domains. That usually means adding them to your allowlist.

Check your firewall’s setup guide for the exact steps—it’s a quick fix!

Domains and hostnames

To keep WeTransfer and all its features working smoothly, make sure these domains and hostnames are on your firewall’s allowlist. We’ll let you know if anything changes via product updates, but it’s a good idea to check this page now and then—or follow the section to stay in the loop.
