FTPS vs SFTP: Key Differences Explained

network security file transfer ftps sftp protocol

This page compares FTPS vs SFTP and highlights the key differences between them in a table format.

Introduction:

Both FTPS and SFTP are protocols designed for secure file transfer. FTPS is essentially an extension of the traditional FTP, fortified with SSL/TLS encryption. On the other hand, SFTP operates over SSH, providing secure file transfer through a single, secure channel.

They differ in several key aspects, including the underlying protocols they utilize, channel configuration, authentication methods, encryption approaches, and port requirements.

Difference Between FTPS and SFTP

The following table outlines the differences between FTPS and SFTP across various parameters:

ParametersFTPSSFTP
Full FormFTP over SSL/TLSSSH File Transfer Protocol
ProtocolUses FTP protocol for file transfer.Uses SSH protocol for file transfer.
SecurityOffers security through SSL/TLS protocols.Offers security through SSH protocol.
Port RequirementsUses separate control (TCP port 21) and data (TCP port 20) ports.Uses a single port (TCP 22 by default) for both control and data transfer.
EncryptionSupports encryption of data and commands.Encrypts the entire communication channel.
CompatibilityWidely supported by FTP clients/servers.Supported by SSH servers/clients.
AuthenticationSupports various methods of authentication.Relies on SSH authentication mechanisms.
PerformanceLower due to SSL/TLS negotiation requirement.Faster due to efficient use of SSH.
Directory Listing FormatPlatform dependent.Platform independent.
Key ManagementRequires management of SSL/TLS certificates.Relies on SSH key management and key pairs.

Conclusion:

The choice between FTPS and SFTP hinges on factors like your specific security requirements, compatibility with existing systems, and the ease of configuration that each offers in your environment.
