Hello Cheon, Yes, you are right. Since you have configured 'any' file type in file blocking profile you would get a data-filtering log as 'forward' for all file downloads - atleast. PE is just a file format category which includes file types with extensions exe,zip..etc If an AV profile is not enabled on a firewall policy for an existing session, the file is streamed from dataplane to management plane for Wildfire processing. That file is then received by the end user and buffered by the management plane. If the file is signed by a trusted signer, the file download gets logged in the data-filtering logs with action set to 'forward' and no entry is logged in wildfire web portal. If the file is not signed by the trusted signer, then the management plane creates a hash of file to send it to the Wildfire cloud to run a check against existing signatures in the database. From there on, depending upon whether the hash match exists in the database or not, the corresponding data-filtering log gets marked as 'wildfire-upload-skip' or 'wildfire-upload-success'. Hope that addresses your concern! Thanks and regards, Kunal Adak
