Hi Mr. Potatohead,

that Event is only meaning that KES named with Path to AVP.exe has detected a Suspicious network activity.

Could be a Mail what was downloaded or could be a connection to the Mail Server.

Sometimes it is only a false positive Detection.

But you can additional have a look on the Mail Server what happend on the Timestamp.

Hello, which component exactly detects that? Network threat protection?

do you have any EDR solution available? optimum, expert?

on the KES local interface, you can see Application Network Activity, Which process tried to connect to your server in the period of incident detection time?

Hello @Arian.Mohammad

We are using only KESB for Windows and Linux.

I am not clear about which process tries to connect to server.

The KES Event might be different than originally posted.
