Sensor Proxy provides an on-premises cache and single point of traffic between Tenable Vulnerability Management and Tenable Nessus Agents or Tenable Nessus scanners. Sensors send communication to Sensor Proxy, not to Tenable Vulnerability Management directly. As a result, large numbers of sensors can communicate with Tenable Vulnerability Management with less bandwidth usage. Additionally, Sensor Proxy alleviates overall network traffic by caching agent updates and distributing differential agent updates.
