SFTP is used as a Secure File Transfer Protocol. The industry standard File Transfer Protocol (FTP) transfers files in a non-encrypted form, so it is feasible to "sniff" the data over the wire. At Beckon, we take security seriously and support only SSH File Transfer Protocol (SFTP). This industry standard variant is an alternative to FTP and ensures that all data is encrypted end-to-end.
The best practice is to use public key cryptography in which you generate a public and private key pair, and provide Beckon with only your public key. We never need to see your private key, and you should retain that securely. With your public key, and username we are able to authenticate you, and provide authorization to transfer files to the server over a secure, encrypted connection.
Alternatively, if your software does not support public/private keys, we also support password based authentication. With your username and password we are able to authenticate and authorize you and transfer files over a secure, encrypted connection.
