Click Policies →ESET Endpoint for Windows, then click the three dots next to the policy you want to edit and click Edit.
Click Settings → Network Protection → Network attack protection and click Edit next to IDS exceptions.
Select the Alert, type the Remote IP address (IP address of the machine with the software that scans the network). Alternatively, to set up an IDS exclusion for a locally installed application, type the full path to the .exe file in Application (e.g. C:\Windows\system32\cmd.exe).
In the Action section, select No from each drop-down menu. Click OK → Save → Finish to save the policy. If this is a new policy, assign the policy to the correct groups. After the computers check in, they will get the policy change.
