• Why does Internet facing assets discover domains that do not belong to company domain after clicking "Get Started"?

  After user clicks Get Started, Internet Facing Assets collects domains for discovery based on analyzing IAM logs (like AAD) and Trend Vision One log in information. It then performs a secondary verification check to ensure that the domains collected are indeed associated with your company. There will be delays performing secondary verification. This may cause inconsistency between domain list initially displayed in the beginning and the domain list actually discovered in the end. You may need to wait and check again.

• What is the difference between domains under Internet Facing Assets and the inside of Review Status?

If an added domain's status is "Processing", it means that it is still under review and will not present in Internet Facing Assets list. Please wait until the review process is completed.
  If you encounter an error message saying that the domain already exists while adding a domain to the internet-facing assets, kindly verify the domain's presence on the Review Status page.
