AS2 (Applicability Statement 2)

What is it?

AS2 is a data transfer protocol, designed specifically for B2B (business-to-business) exchanges, that facilities fully automated and secure file transfers.

How does it work?

The AS2 protocol can encrypt the data (but does not necessarily have to), transfer it across an HTTP connection, and decrypt (if necessary) the files being transferred, keeping the data safe.

Why AS2

This protocol was made specifically for the transmission of EDI data between businesses. It moves data seamlessly from one system to another, allowing for real time transmission of EDI documents. This is the preferred transfer method for EDI.

SFTP (Secure File Transfer Protocol)

What is it?

SFTP is a widely used, secure file transfer protocol that can be used to transmit EDI data between partners.

How does it work?

SFTP runs on SSH (Secure Shell), a secure protocol that facilitates data-in-motion encryption and client/server authentication.


The main advantages of SFTP are security and ease of use. This protocol can support large, bulk transfers of data, while keeping the information safe.
