AS2 continues to be one of the most widely-adopted messaging standards in the world. Retailers, consumer product goods, hard-lines, insurance, financial services, petroleum industry, and government agencies have adopted AS2 to safeguard critical business information that represents billions of dollars each year.

AS3 is the draft specification standard that enables vendor applications to communicate EDI (or other data such as XML) over the Internet using File Transfer Protocol (FTP).

AS4 jump-starts ebMS v3 implementations by constraining the options for vendors to implement, as well as provides some specific guidance for using web services as a secure, document-agnostic B2B messaging platform.
