SFTP at Danske Bank allows you to exchange data with the bank using a secure method for sending and receiving files through the SSH File Transfer Protocol (SFTP). This service requires authentication for accessing the bank’s SFTP server and is enhanced by OpenPGP file security for encryption and signing of files. 

What is needed?
To use SFTP, your business system must support integration with the SFTP protocol, and your company must use your own SFTP software (e.g. OpenSSH, SSH.COM or similar) to connect to Danske Bank’s SFTP server.

Furthermore, a District/Business eBanking agreement with Danske Bank is necessary in order to use SFTP, and you must integrate OpenPGP encryption on payment file transfers to the bank.
