FTP vs SFTP – Which File Transfer Method Is Safer?

Published: 11/12/2025

When people search for the difference between SFTP and FTP, they usually want to understand why these two file-transfer methods behave so differently. Both FTP (File Transfer Protocol) and SFTP (Secure File Transfer Protocol) help move files between systems, which is why users often compare FTP vs SFTP, SFTP vs FTP speed, and even ask “Is FTP encrypted?”. These questions matter when choosing between a traditional FTP server and a more secure SFTP server.

In this article, we will explain what each protocol does, how they work, the real SFTP and FTP differences, and which one is safer for your data.

FTP — File Transfer Protocol (FTP)

FTP is a standard protocol used to transfer files between a client and a server. It runs mainly on port 21 and focuses on basic file exchange. It works well for simple tasks but raises safety concerns because FTP is not encrypted. It suits basic website uploads or environments where data protection is not required.

SFTP — Secure File Transfer Protocol (SFTP)

SFTP uses SSH (Secure Shell) to transfer files safely through an encrypted channel. It operates through port 22 and protects both login credentials and file contents. It’s ideal for businesses, secure environments, and any user worried about FTP security or asking “Is FTP safe?”.

Comparison Table – SFTP vs FTP

Aspect	SFTP (Secure File Transfer Protocol)	FTP (File Transfer Protocol)
Protocol Type	Encrypted using SSH	Unencrypted and basic
Connection Port	Uses port 22	Uses port 21
Security Level	High – protects all data	Low – vulnerable to attacks
Ease of Use	Slightly advanced	Very simple
Speed	Slower due to encryption	Faster (no encryption)
Pros	Secure, reliable, protects credentials and files	Easy setup, quick transfers
Cons	Slightly slower, requires SSH access	Risky, not suitable for sensitive data
Ideal For	Businesses, secure file exchange	Simple, non-sensitive transfers
File Transfer Method	SFTP file transfer protocol with encryption	Basic FTP without encryption

Pros & Cons of Both

Understanding the difference between SFTP and FTP helps you choose the right file-transfer method. People compare them because both move files between systems, but one focuses on speed while the other focuses on security. Below is a simple breakdown to help you decide what fits your needs.

FTP – Pros & Cons

FTP is an older file transfer method. Many users search for the difference between FTP and SFTP because FTP still works well in basic environments.

Pros of FTP

Easy to use for simple file uploads
Works well when security is not required
Fast transfers because it has no encryption
Supported by almost all hosting providers
Uses the standard FTP port 21, which is simple to configure

Cons of FTP

Not encrypted, which makes it unsafe for sensitive data
Weak FTP security
Passwords can be exposed during transfer
Not suitable for business compliance
Data can be intercepted easily

SFTP – Pros & Cons

SFTP uses SSH (Secure Shell) to protect the entire connection. This makes it a safer choice, especially for businesses and professionals.

Pros of SFTP

Fully encrypted data transfer
Safe for confidential and financial files
Uses the secure SFTP port 22
Protects both login details and file contents
Reliable across different networks and systems

Cons of SFTP

Slightly slower because of encryption overhead
Requires SSH user access
More complex for beginners
Needs proper key management
May not work on older servers

Final Verdict – SFTP vs FTP

When comparing FTP vs SFTP, think about what matters to you most.
FTP suits small tasks, simple website uploads, and situations where security is not important. It works for beginners who want quick and basic transfers.

SFTP suits professionals, companies, and anyone dealing with important files. Its encrypted protocol, port 22, and secure structure make it the safer long-term choice.

As an expert, I recommend SFTP for most modern users, especially when data safety matters. Use FTP only when the environment is controlled and the files are not sensitive.

Choose the method that matches your security needs and workload.

Conclusion

SFTP and FTP both move files, but they operate very differently. FTP offers speed and simplicity, while SFTP provides safety through SSH encryption. This covers the main difference between SFTP and FTP server and helps you see which option fits different use cases.

Now that you know the key differences, choose the one that fits your goals best.
