SFTP Servers

SFTP is an acronym for SSH File Transfer Protocol. Transferring files through an SFTP server is one of the safest ways to transmit data online. With an SSH FTP server tool, you can transfer files securely over an encrypted SSH connection.

Encrypting files with an SFTP server can prevent unauthorized access (which can help with things like HIPAA compliance). Many SFTP servers come bundled with SCP, which also protects files via SSH.

FTPS Servers

FTPS is an acronym for File Transfer Protocol over SSL, another secure alternative that lets you encrypt FTP transfers with SSL.

Many products combine FTPS and SFTP servers into one software program so you can choose the type of protection you need when transferring files. In this guide, we’re going to look at the top SFTP and FTPS servers on the market.

1. Files.com SFTP Service EDITOR’S CHOICE

Files - Users view

Files.com is a cloud-based file platform with a built-in FTP and SFTP server. Being based on a remote server, this service is able to offer many more features than a traditional SFTP server. The Files.com system comprises of cloud storage that acts as a buffer for all file activities.

Key Features:

  • FTP and SFTP file transfers
  • Data storage capacity
  • Two-factor authentication
  • Scalable pricing structure

Why do we recommend it?

The Files.com service encourages you to upload files onto the provider’s cloud platform and email out links instead of sending out copies. The advantage of this strategy is that it allows your company and each individual user to maintain control over how those files can be accessed and revoking permissions means that the former recipient doesn’t get to keep a copy of the file. All transfers, storage, and viewing are protected by encryption.

Files.com can operate with FTP and SFTP in three different ways.
  1. Files.com itself can operate as an inbound FTP and SFTP server, allowing you and your users to connect to your Files.com account via SFTP. This allows you to use SFTP to access any portion of your Files.com account, even folders that are syncing to other providers, such as Amazon S3, Google Cloud Storage, Azure Blob Storage, Box, Dropbox, Wasabi, etc.
  2. You can Mount an external FTP or SFTP site directly into Files.com as a folder. Files.com acts as an FTP or SFTP Client in this context, making that SFTP site available via the Files.com web interface, API, SDKs, and even other inbound SFTP connections.
  3. You can configure a scheduled Sync, where Files.com will synchronize its copy of a folder or folders on a one-way or two-way basis with the external FTP or SFTP server.

Businesses can use Files.com as a pass-through when sending files to outsiders, storing a backup on the server in case of loss. It can also be used as a collaboration file storage – enabling several users to access and edit a document. Given that files can be left on the Files.com server, it can also be used as a backup service for important system files.

Files.com supports Single Sign On (SSO), Two Factor Authentication (2FA), Data Locality, Data Retention Management, Management Delegation, Audit Trails, Non-Repudiation, HIPAA, GDPR, and everything else needed for a secure and compliant Cloud Managed File Transfer solution.

The security offered by Files.com enhances transfer protocols because it enforces two-factor authentication for file access and uses the typical SFTP -strength protection for files during transmission.

File devices

Files.com is a subscription service with a charge levied, per user, per month. The service is offered in three plan levels: Starter, Power, and Premier. The Starter plan requires a minimum of 5 users and provides a throughput of 1 TB per month. The Power plan includes a data throughput limit of 5 TB per month and requires a minimum of 15 users. The top plan, Premier, offers a data throughput capacity of 5 TB per month a caters to at least 25 users. Files.com is available for a 7-day free trial, which can be extended on request.

Who is it recommended for?

The integration of the Microsoft 365 productivity suite and collaboration features means that this is a good cloud drive option for distributed teams and virtual offices.
