Scan Exceptions
The default maximum file or message size that is scanned is 2048 KB, but you can define a maximum
size of up to 10240 KB. However, setting the maximum size to a high value might affect the UTM's
performance (see “Performance Management” on page 10-1).
From the pull-down menu, specify one of the following actions when the file or message exceeds the
maximum size:
• Skip. The file is not scanned but skipped, leaving the end user vulnerable. This is the default setting.
• Block. The file is blocked and does not reach the end user.
