AS2 (Applicability Statement 2) is a specification of communication protocols developed by the Internet Engineering Task Force (IETF) for the secure exchange of business documents and business-to-business (B2B) transactions over the Internet.

It has been widely recognised by the business community worldwide that the Internet presents an ideal opportunity for the exchange of data both quickly and cheaply. The problem so far has always been that of security, since the Internet is an easily accessible public network.

For this reason, AS2 has been developed in order to exploit the advantages of the Internet and to make B2B transactions over the Internet as secure as possible.

The transport protocol used by AS2 is HTTP (hypertext transmission protocol) which, together with MIME (Multipurpose Internet Mail Extensions), provides a secure solution for the exchange of data over the Internet.

AS2 in effect provides an envelope for your data, allowing transactions to be sent and received securely and directly over the Internet, avoiding the expense of traditional direct connections and the delays inherent in a VAN service.

AS2 is not concerned with the content or validity of the data being sent. It is concerned only with the means of connection and the exchange of data securely and reliably.

Any type of data can be exchanged using AS2, including traditional EDI messages, XML, flat files, spreadsheets and CAD/CAM data. AS2 is widely used in the retail industry and is rapidly becoming a favoured communications protocol.
