I have to put in place a transfer system to receive XML file of more that 1 Go.

This system have to be very secure.

I was about to take SFTP but it's not IIS compatible and some of the senders will probably have IIS servers and it's will add some time for the project to start.

There is no others options that to use FTPS ?

This question came from our site for professional and enthusiast programmers.

SFTP and FTPS are two unrelated protocols – salva Mar 8 '12 at 9:49
I know, I was saying that FTPS is my only other solution but I don't find it sufficiently secure. – Jarzon Mar 8 '12 at 17:52
SFTP, as a protocol, is not more secure than FTPS. A different matter are the particular implementations. – salva Mar 8 '12 at 18:07
Right, but in my case it's more "secure" if I can be sure of the client identity with a SSH key or a SSL cert. – Jarzon Mar 8 '12 at 18:16
I don't know if IIS supports it, but you should be able to use SSL client certificates when using FTPS in order to identify your users. – salva Mar 8 '12 at 18:21

AS2 seems to be the answer !

You can have a SSL cert on the server and also on the client and you have MDN.
