One of my customer recently migrated from R77.30 to R80.10. setup includes 23800 & 2000X TE appliance for remote emulation. R77.30 Emulation log used to show "Verdict Determined By" field whereas same found missing in R80.10 logging.
Has R80.10 retired this field or stopped reading the field value ?
Any Suggestion
Looks like "Not Vulnerable OS" has the same information (just from your screenshots).
I imagine a different field would show up if the verdict was not benign.
