Advanced File Scanning (Beta)
Note
This feature is in Beta currently. Contact your Sales Representative or Support to enable this feature.
You can enable Advanced File Scanning, also known as Large File Support (LFS), for files exceeding the default size when analyzed by DLP, Threat Protection, or File Profile. This will allow you to modify file size limitations and timeout values.
By enabling Advanced File Scanning, you are allowing Netskope to temporarily store large files as specified in the Netskope Master Service Agreement (MSA).
Data Trickling: Sends small amount of data to the client or server while the file is being processed. This will prevent a connection reset due to a request timeout from client or server, while the file is being processed.
The fallback actions refer to the following actions:
Allow - Do nothing at the time of failure and continue processing the policy list.
Alert - Raise an out-of-band alert and continue processing the policy list.
Block - Raise and alert and block the traffic immediately without further evaluating the policy list
