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.
