What are three considerations when deploying User-ID?

When deploying User-ID, it's crucial to specify included and excluded networks to ensure that only relevant traffic is monitored, reducing unnecessary load and potential privacy concerns. Enabling User-ID only on trusted zones minimizes the risk of exposing sensitive user information. Using a dedicated service account with minimal permissions necessary for User-ID services enhances security by limiting the potential damage if the account is compromised.
