We are investigating solutions to the following problem:

We have external (Internet) users who need access to sensitive information. We could offer it to them via SFTP which would offer a secure transport method.

However, we don't want to maintain the data on server as it would then reside in the DMZ.

Is there an SFTP server that has "copy on access" such that if the box in the DMZ were to be compromised, no actual data resided on that box?

I am envisioning an SFTP Proxy or SFTP passthrough. Does such a product exist currently?
