Transferring files over the internet is the quickest way possible. However, it can also be quite risky, as the internet is filled with cybercriminals who are always hunting for crucial data to steal. If that happened, you would be devastated, especially personal data such as credit card information.

Let’s dive right in.
What Is an SFTP Server?
SFTP stands for SSH File Transfer Protocol and is among the most popular and secure ways to transmit data online. An SFTP server is usually the last destination at the receiver’s end that offers safe file transfers when exchanging messages over SSH (Secure Shell) to ensure access to every shell account on a remote SFTP server.
This method allows you to encrypt your data when sending it, making it impossible for unauthorized parties to hijack it.
You should not confuse SFTP with FTP technology. FTP is a standard technology used by many people to share data. However, this method does not encrypt data, making it easier to be stolen or even lost. Also, crucial information such as credentials is usually sent in plain text, which even doubles the theft risk.
Luckily, SFTP servers came as a better and safer alternative to help avoid all those issues. SFTP servers ensure encrypted connections and even prevent the transfer of any unencrypted data.
The Best SFTP Servers
Our methodology for selecting SFTP servers
We reviewed various SFTP servers and analyzed the options based on the following criteria:
- Access control features
- Ability to schedule or automate tasks and processes
- Ease of use for end users
- A facility to analyze file transfer performance over time

1. Files.com – FREE TRIAL
Files.com is a cloud-based file management system that mediates file transfers. So, you don’t directly send the files to your target recipients. Instead, you upload the files to the system, and then you grant access to every recipient. That way, they will be emailed a link to facilitate private and secure access to the uploaded file. This can be pretty handy, especially when sending a file to many people and you want to do so in the fastest way possible.
Key Features
- Complete MS Office Integration with folder/file previews
- Unique links for file upload and download
- Assigns permissions to groups, folders, and users
- Robust and thorough audit logs of file and user modifications
- 2FA (2-factor authentication)
Why do we recommend it?
Files.com gives you a lot more functionality than just file transfers. The package includes cloud storage space, giving each of your users an account to hold files. This enables collaboration and distribution without actually moving the file further. Security is easier to implement when you still have control of all files.
If you send attachments frequently, then Files.com could be an excellent tool for you. Files.com intercepts your emails and uploads the attached file on the system. Once done, it places a link to the file in the email’s body, which is more secure as no unauthorized person can access the file now, even if they logged in to your email account.
Files.com offers SFTP, FTP, and WebDAV transmission protocols. You can access files with WebDAV over HTTPS, adding a TLS security layer to your data transfer. The SFTP option usually provides SSH security to your file transfers. Plus, the assigned storage areas on the server are traditionally highly encrypted. TLS handles file viewing access via the HTTPS protocol.
Users on this server get individual access credentials for each account. Therefore, you can quickly identify which user performed a particular action in the account.
Who is it recommended for?
This package is suitable for any business of any size. It provides a cloud drive for all employees, so it would be particularly useful for a company that operates a virtual office or has a lot of remote workers. Link invites remove the need to send files out by file transfer or email attachment.
Pros:
- Scalable solution, making it ideal for both small businesses and enterprises alike
- Features robots user management, permissions, and access control to support long-term use
- Allows users to create links to files that have special rules, such as expiration dates or click tracking
- Can compress large files for faster transfer
- Supports integrations into other cloud-based storage options such as Dropbox, Google Drive, and OneDrive
Cons:
- While the platform is easy to use, some of the more advanced features can take time to learn and implement
Files.com is an excellent tool for anyone looking for a mix of class, complexity, and reliability. The tool goes for $50 per user per month, but you can sign up for a 7-day free trial. Files.com works on all platforms.
2. ExaVault – FREE TRIAL

- User account controls, including multi-factor authentication
- Link forwarding for file sharing and distribution
- Facilities for managed file transfers
- Activity logging for compliance auditing
Why do we recommend it?
ExaVault is a similar system to Files.com. It provides a cloud drive for each employee, removing the need to send files outside the building. Employees can invite each other to access files and outsiders can also be given a link to access the file in place rather than sending it out.
The platform greatly reduces the number of transfers that need to be performed because plans include file storage space, so it can provide a company’s file server. Users then store all of their files on the ExaVault system and grant access to colleagues for collaboration.
Sending copies of company files to outsiders can be implemented in a very secure way by leaving the files on the server and just mailing out an access link to all recipients. Those recipients then access the file on the ExaVault server. Thus, all access to data can be logged and controlled.
The access rights that are granted can be adjusted by permission levels and they can also be issued with time limits. Users and the administrator can revoke access to files.
Who is it recommended for?
This package is a good choice for businesses that handle large files. Moving large files is fraught with failure, so it is better to let others access those files on the ExaVault platform rather than trying to mail them out. The package is priced per user with a minimum team size of five.
Pros:
- Simple user interface
- Can integrate with other cloud-based storage platforms such as Google Drive
- Uses intelligence file sync to keep track of files and eliminate duplicates
Cons:
- While the platform is easy to use, some of the more advanced features can take time to learn and implement
