Web Security: Virus-Scans for FTP uploads
With Web Security you can scan ftp downloads for viruses. But you cannot protect your own ftp server because the Web Security doesn't support virus scanning for ftp uploads. So it would be important to support virus scanning for ftp uploads.
This feature was implemented in Sophos UTM v9.2. All FTP uploads as well as downloads are now scanned.

This is a good one. I thought it would have been covered by the new Web Application Security feature since it's job is to protect internal web servers, but apparently not. It only scans for web-based attacks like injections etc.
Inbound FTP connections are something that must be protected too.
