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.
AS2 Pre-Certification is required for new or past AS2 vendors who have not participated in Drummond B2B AS2 Test Events within the last two years.
