The safe, secure and completely free way to transfer large files around the Web.
What is ZendTo?
It is a classic problem: you need to send files to someone, or they need to send them to you, and there's no way except email. But they are too large or your administrator won't let you transfer the files by email at all. ZendTo to the rescue!
ZendTo is a completely free web-based system, which you can run on your own server with complete safety and security. It runs from any Linux or Unix server or virtualisation system and there is no size limit and it will send files 50% faster than by email. It will also integrate with any Active Directory, LDAP or IMAP system you already have in place.
If you are in a customer service organisation, ZendTo can integrate with your customer service ticketing system so that all your references are kept in one place.
Technical support is provided by email or an active mailing list. All completely free.
