What is Secure FTP?
Secure FTP is a network protocol that transfers files between clients and servers. It augments the simple file-transferring capability of FTP with layers of security. FTP itself has no security features that must be taken care of by other means, either by augmenting this protocol with SSL/TLS, called FTPO or by using SFTP, which is actually called SSH File Transfer Protocol.
These secure file transfer protocols ensure that your data is secure within and outside of your organization. Secure File Transfer Protocol (SFTP) uses Secure Shell (SSH) for authentication and encryption; it’s a secure alternative to traditional FTP.
SFTP allows files to be sent between clients and servers in encrypted form. It replaces conventional FTP with a much more secure way of sending or saving data across locations.
How Does Secure FTP Work?
Secure FTP incorporates the secure authentication and encryption of SSH along with file transfer capability. This means that files are encrypted during transfer, hence enhanced security. SFTP allows users to upload, download, and generally manage files on remote servers in a secure manner. This means that sensitive data is properly guarded during transmission.
A widely supported protocol, SFTP has undergone many versions to fix security vulnerabilities and improve performance. New versions are introduced with stronger encryption and authentication schemes to provide strong protection. Across many industries, such as finance and healthcare, SFTP remains the solution for secure file transfers, providing peace of mind and integrity in data.

How Is SFTP Different Than FTP?
Here are the key differences between SFTP (SSH File Transfer Protocol) and traditional FTP (File Transfer Protocol):
| Feature | SFTP | FTP |
|---|---|---|
| Encryption | Encrypts both data and commands | Does not encrypt data |
| Authentication | Utilizes SSH for secure authentication | Relies on plaintext authentication methods |
| Port Usage | Operates on a single port (usually 22) | Uses separate ports for data and commands |
| Protocol Complexity | More complex protocol with advanced features | Simpler protocol with basic functionality |
| Platform Support | Widely supported across various OS | Historically supported but becoming less favored |
Encryption
SFTP (SSH File Transfer Protocol) encrypts both the data and the commands sent between the client and the server. In contrast, FTP does not inherently encrypt the data and thus is susceptible to interception or unauthorized access by hackers.
Authentication
SFTP uses SSH (Secure Shell) for authentication; it’s a very secure way to verify user and server identities. In contrast, many implementations of FTP usually rely on plaintext authentication methods, which carry a number of security risks, such as password sniffing and unauthorized access.
Port Usage
SFTP operates on a single port (usually port 22), simplifying firewall configurations and enhancing security by minimizing the number of open ports. FTP, however, uses separate ports for data transfer (port 20) and commands (port 21), which can complicate firewall settings and increase vulnerability to attacks.
Protocol Complexity
SFTP is a much more complex protocol than FTP, giving lots of advanced features, such as file integrity checks, file and directory listings, and remote file management. FTP is much easier to implement but lacks integrated secure file transfer support and needs additional measures to secure data.
Platform Support
SFTP is natively supported on many operating systems, including Windows, Linux, macOS, and most Unix-like operating systems, giving it very flexible use in secure file transfers. FTP, though used far and wide in times past, is finding less and less favor due to inherent security vulnerabilities and a lack of encryption.
FTP vs. SFTP vs. FTPS
| Feature | FTP (File Transfer Protocol) | SFTP (SSH File Transfer Protocol) | FTPS (FTP Secure) |
|---|---|---|---|
| Security | No built-in encryption; data transmitted in plain text | Encrypted data transmission over SSH protocol | Encrypted control and data channels |
| Authentication | Username and password | Username and password, SSH keys | Username and password, SSL/TLS certificates |
| Port | 21 (Control), 20 (Data) | 22 (default for SSH), customizable | 990 (Control), 989 (Data) |
| Firewall | May require additional configuration for passive mode | Can traverse firewalls using a single port (22) | May require special firewall rules for passive mode |
| Platform | Cross-platform | Cross-platform | Cross-platform |
| Best Use Cases | Transferring non-sensitive files within a trusted network | Secure file transfer over an untrusted network | Compliance requirements, secure file transfer in a trusted network |
| When to Choose | When security is not a concern, and simplicity is prioritized | When secure file transfer over an untrusted network is required | When compliance mandates SSL/TLS encryption for data transfer |
Conclusion
With the permanent threat of attacks that may be present in our digital era, a secure FTP server is imperative. More precisely, this becomes a necessity in industries that store sensitive information. With secure FTP, all stringent data encryption measures serve to give assurance to stakeholders that their information is kept safe.
A comparison of the secure FTP against insecure methods shows tremendous differences. Secure FTP, powered with robust encryption and verification tools, assures the safety of information to the best degree possible.
