Welcome to Sensor Proxy

Last Updated: October 15, 2026

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

Note: Tenable Security Center 6.5 only supports Sensor Proxy linked with Tenable One Web App Scanning scanners. Tenable Nessus scanners and Tenable Agents are currently unsupported. Tenable One Vulnerability Management supports Sensor Proxy linked with all sensors except Tenable One Web App Scanning scanners.
