The authentication methods and list of commands are different for both protocols. SFTP has greater compatibility and adoption. FTPS file transmissions are multiple times faster than those made using SFTP. You will therefore have to open a range of ports in your firewalls to allow for FTPS connections, which can be a security risk for your network. Every time a file transfer request or directory listing request is made, another port number needs to be opened for the data channel. The first port for the command channel is used for authentication and passing commands.
SFTP needs only a single port number for all SFTP communications, making it easy to secure. SFTP works seamlessly with firewalls, but its binary data transmissions are not suitable for logging. You should keep the following details in mind before selecting a protocol: - SFTP is inherently secure and fully encrypted, while FTPS adds a layer of encryption using SSL or TLS. SFTP and FTPS are popular secure file transfer protocols for transferring files over public and private networks: - Although both secure protocols have their pros and cons, we recommend SFTP due to its better usability with firewalls. What are the Differences Between SSH File Transfer Protocol (SFTP) vs.
