Required User Role: Administrator
A primary domain is associated with an account when you initially create an account. You can create multiple secondary domains that you can associate with your partner Tenable Vulnerability Management accounts, which allows you to track and manage your Tenable Vulnerability Management accounts.
The free version of Tenable Attack Surface Management uses the data from the primary domains to populate its Attack Surface Management (ASM) data. Any domain that you set as primary cannot be disabled. This ensures that you do not delete that domain by mistake.
