Hi,
What data are you trying to move to the appliance? Threat alerts, computer information? I assume it's not just the log files of the product as I don't think they would mean too much.
What format can the appliance consume, some sort of seperated text file?
Does the "client" have to push the files or can the appliance read? Could the appliance perform SQL queries on the database?
It maybe that the Sophos Reporting Interface and the Log Writer could be used for this. It depends on what data you are trying to move.
Some info is here:
Even if you didn't use the Log Writer, but just installed the interface (this is installed in the 5.1 verison by default) you could write a simple script to just dump data to a file that the appliance could pick up.
Regards,
Jak
