Dear Rashmi,

AS2 is a direct Point-2-Point Connection, which allows the Sender (due to the signed MDN) to be 100% sure that the data has been received on the partner side and could be processed correct.

For example if your partner has some difficulties in decrypting the data, then you will automatically get a negative MDN and be aware about this.

In sFTP, you upload the data to an sFTP-Server and therefor you only know, that the file has been uploaded there, but you don´t know if your partner has already picked up the file from there...

AS2 is most commonly used in EDI-scenarios, but can of course be used for any kind of data. It is used a lot in the Retail-Area (big retail chains connecting their suppliers) but also in the Banking-Sector.

Thanks Ryan for your reply. And i agree with the point that it depends on the requirement as per the client. In our case they agreed to use SFTP adapter with PGP encryption.

Hi Experts,

Could you please let me know which one to prefer for bank communication scenario and why ?

Thanks

Varun,

- As2 works on HTTP protocol aka Transport Layer Security

- AS2 performs encryption using Digital Signatures and their corresponding algorithms.

- SFTP works on SSH Protocol aka Network Layer Security.

- SFTP transmissions typically uses PGP Encryption.

The decision between either of them is more a Infrastructure availability, vs downstream system vs Firewall/ Security experts decision.

In my experience, banks typically prefer SFTP with PGP. Havent seen banks using AS2 as a transmission protocol.

Thanks Bhavesh, we also prefer to go with the SFTP and suggested client to use SFTP for bank communications.

Hi Varun,

We have all bank communications handled via AS2 - I think it all depends on your requirement as far as what type of messages you are sending/receiving and if you need acknowledgement or other special handling that you would not get with SFTP.

Hi Rashmi,

AS2 adapter is specifically for EDI scenarios (ANSI X12 or EDI FACT) while sFTP adapter is used for general file scenarios.
