Choosing between AS2 (Applicability Statement 2) and SFTP (SSH File Transfer Protocol) depends on your industry requirements and the type of data you are exchanging. AS2 (Applicability Statement 2)
AS2 is a server-to-server protocol designed specifically for B2B transactions, particularly Electronic Data Interchange (EDI). It transmits data over HTTPS, using digital certificates and encryption for security.
Key Feature: Non-Repudiation. AS2 is unique because it provides Message Disposition Notifications (MDNs), which are signed electronic receipts that confirm a message was received and decrypted successfully. Best For:
Retail & E-commerce: Required by major retailers like Walmart and Target for supply chain communications.
Regulated Industries: Ideal for healthcare (HIPAA) and finance (PCI DSS) where proof of delivery is legally critical.
Mandated Partners: Use it if your trading partners require it to ensure compatibility. SFTP (SSH File Transfer Protocol)
SFTP is a versatile protocol that uses the Secure Shell (SSH) protocol to provide a secure channel for transferring files. Which is Better: AS2 vs. SFTP? – GoAnywhere
