Sync to SFTP, Amazon S3 and Other Clouds

Customize your solution

Sync to and from S3, synce to SFTP and other Clouds with Hosted~FTP~’s custom solutions. Check out other example features we can add to your solution below.

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”ť 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).

Sync to SFTP, Amazon S3 and Other Clouds FAQ

What is HostedFTP’s Sync to S3 feature?

Our Sync to S3 feature allows external clients to securely upload files directly into your Amazon S3 bucket—without giving them access to your AWS credentials or internal infrastructure.

Can users download files from my S3 bucket without having access to AWS?

Yes. HostedFTP enables secure, permission-based download access from your S3 bucket without exposing AWS permissions to customers or partners.

How does HostedFTP sync files to an external SFTP site?

You can configure HostedFTP to automatically push files to an external SFTP destination as soon as they are uploaded to a designated folder—fully automating your outbound sync workflows.

Is HostedFTP compatible with other cloud services besides Amazon S3?

Yes. While Amazon S3 is a key integration, HostedFTP also supports syncing with other cloud and FTP/SFTP environments through custom workflow configuration.

What security measures are in place for cloud-based transfers?

All file syncs use end-to-end encryption (FTPS, SFTP, HTTPS), and run within your own private AWS environment using 256-bit AES encryption. Granular folder permissions and user roles provide additional layers of control.

Can I control access to synced folders for different users or teams?

Yes. With folder-level permissions and group/role-based access control, you can assign read, write, or upload-only permissions per team, client, or user group.

How do I know when a file has been uploaded or synced?

You can configure real-time email alerts for uploads, downloads, and transfer failures—helping you stay informed and compliant.

What’s the maximum file size I can sync?

There are no practical file size limits. HostedFTP supports large file transfers via AWS-backed elastic infrastructure, making it ideal for high-volume or high-size scenarios.

Can I embed a file upload tool on my own website?

Yes. You can use our Web Upload Plug-In to add a secure file submission form directly on your website—great for receiving files from clients or partners.
