Unlink an Agent

When you manually unlink an agent, the agent disappears from the Agents page, but the system retains related data for the period of time specified in agent settings. When you manually unlink an agent, the agent does not automatically relink to Nessus Manager.

Tip: You can configure agents to automatically unlink if they are inactive for a certain number of days, as described in agent settings.
