When you import an encrypted file from an external FTP, why are two File Transfer activities needed?

When importing an encrypted file from an external FTP, two File Transfer activities are necessary to ensure the proper handling and security of the data. The first activity is responsible for transferring the encrypted file to a secure location, often referred to as a safehouse, where sensitive data can be stored securely before any further actions are taken. This step is crucial as it ensures that the file is kept safe during the initial transfer process.

The second activity involves decrypting the file once it is securely stored in the safehouse. Decrypting is essential because the data must be in a readable format for subsequent use or analysis within the Salesforce Marketing Cloud. This separate step not only maintains security protocols by ensuring that decrypted data is only processed in a controlled environment but also adheres to best practices for managing sensitive information.

Thus, the combination of these two distinct activities—one for secure transfer and one for decryption—ensures that the process is both efficient and compliant with security standards, allowing for the safe handling of sensitive data.
