Install Tenable Nessus Agents

Before you begin the Tenable Nessus Agents installation process, you must retrieve the agent linking key from the Tenable Nessus Manager user interface.

Once you retrieve the linking key, use the procedures described in the Tenable Nessus Agent User Guide to install the agent and link it to Tenable Nessus Manager.

Once installed and linked, Tenable Nessus Agents are linked to Tenable Nessus Manager after a random delay ranging from zero to five minutes. Enforcing a delay reduces network traffic when deploying or restarting large amounts of agents, and reduces the load on Tenable Nessus Manager. Linked agents automatically download plugins from the manager upon connection; this process can take several minutes and you must perform it before an agent can return scan results.
