  • I have installed Acunetix on a internal system (private ip).We are using it to scan websites hosted both internally and externally.
    There are 2 questions
    1. Does Acunetix v9 automatically updates itself or not ?

    2. If it updates automatically how will it connect to acunetix server for updating its database for new exploit and testcases if i have deployed consultant edition internally and there is firewall in between.

    Which port number does it use for updating and what is the Ip address of the Acunetix server which provides the updates so that we can whitelist that Ip address in our firewall
