    Hi ,

    Thanks for reaching out to the Community! 

    This alert means the traffic generated by the user matched the known IPS signatures. The recommended action is set to "Drop packets" for SID 38085 and 38086. 

    Reference screenshot: 

    You can find more information at Sid 1-43758.

    Thanks,

  • Hi Harsh, thanks for the quick response, this client is up to date with patches and Sophos endpoint has not blocked anything, is there anything else I should do on the computer?

    Hi ,

    The Sophos XG firewall already has the protection for this detection with those two SIDs mentioned in my previous reply. 

    If IPS policies are configured on your firewall rule, then you don't have to worry about this detection. On the computers, ensure that the browser version is updated and not one of the affected versions mentioned in the link. 

    Thanks,
