Why is SFTP more secure and faster than FTP?
Why SFTP is more secure and often faster than FTP for transferring website files.
SFTP (SSH File Transfer Protocol) is the recommended way to transfer files to your webhosting. Here is why it outperforms traditional FTP.
Security
FTP sends your username, password, and file contents in plain text. Anyone on the network can intercept them.
SFTP encrypts all data—credentials and files—over SSH. Your connection is protected from eavesdropping and tampering.
TIP
Always use SFTP for file transfers. PlanetNode supports SFTP on all webhosting packages.
Speed and efficiency
- SFTP uses a single encrypted connection (port 22) for both commands and data, reducing overhead
- FTP uses separate channels and can be slower, especially on unstable networks
- SFTP often performs better with many small files and over high-latency links

| FTP | SFTP | |
|---|---|---|
| Encryption | No | Yes |
| Port | 21 | 22 |
| Security | Plain text | Encrypted |
