SFTP

Security

We use the Secure File Transfer Protocol (also called SSH File Transfer Protocol) to transfer files, which has the following benefits:
  • It's in accordance with industry standards.
  • SFTP is based on a strong AWS Key Management Policy (using an Advanced Encryption Standard algorithm in Galois/Counter Mode with 256-bit secret keys).
  • We isolate your data from other customers' data.
  • We use an AWS S3 bucket to store files during import, but once imported to ONESOURCE Indirect Tax Compliance, we delete them from storage.
  • Your access to a dedicated SFTP folder is protected by SSH key certificate-based authentication.

Set up an SFTP client

  1. You'll need an SFTP client such as FileZilla, WS_FTP, WinSCP, and Open SSH to connect to your SFTP location and upload data.
  2. Share the certificate public key with us to enable your SFTP account via certificate-based SSH authentication.
  3. Once you've enabled your account, use the corresponding private key to access your SFTP folder in the AWS S3 bucket.
    note
    You'll have your own root folder. The "Home directory" will be the root folder and its structure is
    /<s3 bucketname>/<environment>/username
    . For example,
    /a204253-oitc-emea1-prod-awstranser/emea1/f09
    .
  4. Upload your files.
    note
    You can upload files up to a maximum of 200 MB. This is flexible according to the data (that is, the number of fields). If you have larger files, break them down before importing.

Upload configurations

  • Automatic uploads
    : If you want to set up automatic uploads of your data, contact our Professional Services team to configure it for you.
