[Defender Pro] More information in the description of each entry in 404 Detection logs

I am running a multisite and I have decided 2 months ago to dump Wordfence for Defender.

One major issue I am still facing ever since is related to the inability to determine the real path/file that the hacker or even the legitimate user is after. To be exact, I am getting entries like :
” 404 Request for file /datafiles/images/Text7.jpg which doesn’t exist” and you cannot really tell from this which site this user was targeting. More than that this was coming from a legitimate user for which I have verified that at that time he was not looking at a web page with this file and this file doesn’t indeed exist… so how could he have made this request in the first place?

I would love to have more information to make an educated guess and decide to either block or allow the user to my sites.

Thank you very much for your attention.

Best regards,
