How do I use the Scanner Appliance Proxy?

Many organizations require traffic to be passed through a corporate HTTP or HTTPS proxy before it can hit the Internet. This means any requests to the Internet should first go through the proxy server first.

With this feature enabled, the proxy server forwards probe requests to the Holm servers. It acts as an intermediary, facilitating the flow of information and providing an added layer of control and protection.

The Scanner Appliance Proxy works with the most common stable proxies: HTTP and HTTPS, both authenticated (with username and password) and non-authenticated.

How do I configure the Proxy?

1. The Proxy must allow traffic to Holm Security servers so the Scanner Appliance can reach Holm Security servers via proxy. Check this article to see the firewall settings.
2. Your Scanner Appliance needs to have at least version 59 to have access to the proxy.
3. Open up the Scanner Appliance virtual machine in your virtualization platform.
   1. Go to configuration > Proxy.
   2.  Type in the Proxy URL and click F11 to save.
   3. Done!

What external communication to Holm Security servers is covered by the proxy?
