FTP vs SFTP: Which Should You Choose?

When it comes to transferring files between computers, two protocols are typically used: SFTP (Secure File Transfer Protocol) and FTP (File Transfer Protocol). If you are operating a website or plan to manage one, knowing the difference between the two is essential.

If you’re unsure which one to use for your website, keep reading to decide which one is right for you.

In this blog post, I will do a quick FTP and SFTP comparison. I will share key differences and similarities between the two, and give tips on how to set up both.

What is FTP?

FTP, which stands for File Transfer Protocol, is the standard protocol used to transfer files between a client and a server over a network, such as the Internet. 

It was one of the earliest protocols developed for transferring files and is still widely used today. FTP is a relatively simple protocol, with a client-server architecture, that allows files to be transferred between two computers.

What is SFTP?

On the other hand, SFTP, which stands for Secure File Transfer Protocol, is a more secure version of FTP. Rather than using traditional FTP commands, SFTP encrypts the data being transferred.  It uses Secure Shell (SSH) transfer protocol, making it a much safer method for transferring sensitive files.

SSH file transfer protocol is widely used by businesses and organizations that need to prioritize data security to transfer large files, such as financial data or medical records.

FTP vs SFTP: Key Differences and Similarities

Now that we understand the basics of what FTP and SFTP are, let’s dive into their differences and similarities:

Key Differences Between FTP and STFP

• The most significant difference between FTP and SFTP is security. As we mentioned earlier, SFTP encrypts the data channel being transferred, making it impossible to intercept or tamper with data. FTP, on the other hand, does not have any built-in encryption. So, file data sent through FTP are susceptible to interception.
• For users, SFTP requires more technical knowledge than FTP. Because SFTP encrypts the data being transferred, it requires public and private keys to establish and authenticate the connection. FTP, on the other hand, is a more simple protocol for those who do not have a technical background.
• Another difference is the ports used by both protocols. FTP uses port 21, while SFTP uses port 22. This difference can cause issues in some networks where certain ports are blocked.  

Key Similarities Between FTP and STFP

• Both protocols are used for file transfers between computers remotely. 
• They also support resume or restart capabilities, which means that if a connection is lost, you can pick up where you left off rather than having to start the transfer over again.

File Transfers for Mac and Windows OS

Both FTP and SFTP support Windows and Mac operating systems.

However, Mac users don’t need to download additional software or programs because the operating system comes with a built-in terminal and SSH client.

On the other hand, Windows users need to download third-party applications to use SFTP.

FTP and SFTP: Setup Guides

Before deciding which file transfer process you will use, you may want to know how to set them up properly. The setup for each of the two differs depending on the platform you are working on. 

How To Set Up FTP:

Setting up FTP is much simpler than SFTP. 

1. The first step is to download and install an FTP server on the computer that will be hosting the files.
2. Once you have completed step one, you can connect to the server using an FTP client, such as FileZilla or Cyberduck. 
3. After you have connected to an FTP client, you can upload or download files over the unencrypted FTP connection.

Note: Make sure to check out this step-by-step tutorial on how to configure an FTP client with your hosting provider. 

How To Set Up SFTP:

Setting up SFTP is relatively easy, but it requires some technical know-how. 

1. To get started, you need to generate a pair of public and private keys, which will be used to authenticate the connection. 
2. It’s important to note that SSH/SFTP is disabled on all Web Hosting and Reseller Hosting accounts by default.  Check out this guide to quickly learn how to connect your web hosting account using SSH And SFTP.
3. You can then connect to the server using an SFTP client, such as FileZilla or WinSCP. From there, you can transfer files over the encrypted SFTP connection.

FTP vs SFTP: What Should You Choose?

Now that you know have a better idea of both FTP and SFTP, which one should you pick? 

The answer depends on your specific needs. If you are transferring sensitive data and require a secure connection, then SFTP is the way to go. However, if you need a more simple method to transfer files and do not need added security, FTP is a great option.

Conclusion

FTP and SFTP are both file transfer protocols that have been used for years to transfer files between computers. While FTP is a reliable and straightforward option, it lacks the security features that SFTP provides. If you’re dealing with sensitive data and require a secure channel, SFTP is the way to go. 

If you’re unsure which one to use, consider your needs carefully and choose the one that is right for you. 

With the right client software and login credentials, both FTP and SFTP are excellent ways to transfer files between computers. 

We hope this guide helps you in making a decision on which file transfer protocol you’d like to go for!
