BPA+ PE File Size Limit

The file size for PE files should be set so all PE files that pass through the firewall are sent to WildFire for inspection. Each firewall model has a different disk buffer size for forwarding to sandbox, increasing the maximum PE file size limit may affect forwarding capacity in terms of the number of files the firewall can forward.

It is possible that not all files would be forwarded to WildFire if multiple bug zero-day files are processed at the same time. You can tune the maximum size setting and observe whether there’s enough buffer space to handle a higher limit. The Best practice assessment check ensures the file size limit for PE files is set to 16MB.
