Good Day,

We are using Sep 12.1 RU 1 MP 1 and doesn’t using SEP firewall module on Machines and some of the Machines IPS is blocking an application and logging an event with Severity: Critical, while we are trying to run our vulnerability Check from VA application?

You can add the IP of the VA server in the exlcuded hosts file in the IPS policy. See here

Yes it still applies in your case. Firewall and IPS are apart of Network Threat Protection but are separate components. You can use both or only one.

Hi!

In my opinion it is applicabale in your case. Or You can use application learning and you should add it to exclusion list.
