During a domain discovery scan, Halo might find additional hosts that we believe are part of your attack surface. These hosts can be added as targets for additional scanning or marked as an acknowledged host. Here are the steps that should be taken to mark a host as trusted:
Log in to your dashboard.
Select the target you'd like to add as an acknowledged host.
Click the + icon to the right of hostname.
Select Acknowledge Host.
Managing acknowledged hosts
To view and edit your acknowledged hosts, click Settings → Acknowledged → Hosts in your account.
