Sync to SFTP, Amazon S3 and Other Clouds

Sync to S3

In many circumstances, there is a requirement to have files transferred by customers/3rd parties directly to your S3 buckets. There are significant problems with your customer setup and security in terms of providing them with access privileges to your S3 bucket. The Sync to S3 bucket file transfer solves this dilemma and provides a “secure gateway” to enable this functionality.

Sync from S3

Equally as important is to be able to give customers/business partners the ability to download files/documents that are stored on your S3 buckets without providing access to your internal site.

Sync to SFTP

The service also allows for files to be transferred to an external SFTP site as soon as a file is uploaded to a specific folder(s) from a specific user(s).
