A large number of port scans

L0 Member

Hi guys! 


Recently, we often encounter incidents associated with a large number of port scans in Cortex XDR. We assume that this started after the last update. Does anyone else have something similar?


Thank you!

Hello Latif,


we haven't encountered any issue like that but something similar happened when we have defender on passive mode for systems on W10. As the sensor in defender checks for devices on the network , XDR terms as port scan.


Hope this helps
