Setting up ATR for Barracuda Impersonation Protection

What ATR does

ATR determines whether an alert is malicious.

If the alert is identified as malicious, the IP Address is automatically added to the firewall or network security solution block list, depending on how malicious ATR determines it to be.

For more information about Automated Threat Response (ATR), see Setting up ATRPreview.
