Secure Electronic File Transfer

Secure Electronic File Transfer (SEFT) allows an NHS Digital Business Team to transfer data to and from any external organisation electronically and securely. The service allows us to provide a secure wrapper around any file, irrespective of file type, size, structure or data content.

How are the data kept secure?

SEFT provides data security during transmission (by using a 256-bit AES encryption mechanism) and at rest. The data are held in secure containers at NHS Digital and only the individuals authorised to process the data are allowed access.

How do I access it?

We will invite relevant people to register for the service, and send you log-in details. For further information, please contact the SEFT team at
