Install Nessus Agent
This section describes how to install a Nessus Agent on the following operating systems:
Once installed, an agent links to Nessus Manager or Tenable.io 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 Nessus Manageror Tenable.io. Agents automatically download plugins from the manager upon linking; this process can take several minutes and you before an agent can return scan results.
