Palo Alto Network’s data retention policies for samples
submitted to the WildFire cloud have been updated. Files sent to
the WildFire cloud for processing and analysis are retained until
processing takes place. Once analyzed, files categorized as benign
are now retained for 14 days in case the analysis decision is reversed.
As before, files determined to be malicious are retained for 10
years. Furthermore, signatures and sample reports for corresponding
files, which do not include personal information, will continue
to be stored indefinitely.
