Link a Tenable Nessus Scanner to Sensor Proxy

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

If you have a Tenable Nessus scanner that is already linked to either Tenable Vulnerability Management or Tenable Nessus Manager, you must first unlink the Tenable Nessus scanner.

For unlinked Tenable Nessus scanners, you can link to Sensor Proxy to communicate via Sensor Proxy to Tenable Vulnerability Management.

Note: If you relink a scanner, the scanner restarts. For several minutes after relinking, the scanner does not perform scan jobs.

Before you begin:

Install Sensor Proxy.

To link a Tenable Nessus scanner to Sensor Proxy:

If your Tenable Nessus scanner is already linked to a manager, unlink it using the following command.
Copy
```
# nessuscli managed unlink
```
The scanner is unlinked from its manager.
Link the scanner to Sensor Proxy using the following command:
Copy
```
# nessuscli managed link --key=<linking key> --host=<Sensor Proxy IP or hostname> --port=443
```
- For key, use the Tenable Vulnerability Management linking key. For information on retrieving the linking key, see Link a Sensor in the Tenable Vulnerability Management User Guide.
- For host, use the Sensor Proxy IP address.
Note: (Optional) You can add other Tenable Nessus linking options, except for the --cloud option. For more information, see Nessus CLI in the Tenable Nessus User Guide.
