Secure, dependable SFTP and FTP(E/S) server for Windows

Ultimately, running an SFTP (or FTP/ES) server is all about security and reliability.

Whether you need to run a mission-critical, HIPAA compliant file transfer server, or you want to securely backup your Cisco UCM, you need to make sure that your SFTP server can handle the workload while protecting you from external threats at the same time.

You also want your SFTP server to be extensible, to be able to run your own scripts, and execute your own workflow. At Syncplify we understand that every customer has unique needs, that's why we designed Server! to fit them all by blending a full scripting framework and event-handling subsystem into it.
