Upgrade Notes
-
Tenable Nessus Agents upgraded via Tenable Nessus Manager cannot upgrade to 8.2.0 and later unless Tenable Nessus Manager is already updated to 8.12.0 or later.
-
New Tenable.io Domain - As a part of continuous security and scalability improvements to Tenable infrastructure, we have added a new sensor.cloud.tenable.com domain that Tenable Vulnerability Management-linked Tenable Nessus Agents communicate with.
-
Starting with Tenable Nessus Agent 8.1.0, Tenable Vulnerability Management-linked Tenable Nessus Agents communicate with Tenable Vulnerability Management using sensor.cloud.tenable.com. If agents versions 8.1.0 through 10.3.1 are not able to connect to the new domain, they fall back to using cloud.tenable.com. Tenable Nessus Agent 10.3.2 and later do not fall back using the cloud.tenable.com domain.
- Recommended Action: If you use domain allow lists for firewalls, Tenable recommends adding *.cloud.tenable.com (with the wildcard character) to the allow list. This ensures communication with sensor.cloud.tenable.com and all future subdomains, reducing operational overhead. Contact your network administrator for assistance with making necessary changes to your allow list.
-
- You can upgrade to the latest version of Tenable Nessus Agent from any previously supported version.
- If your upgrade path skips versions of the Tenable Nessus Agent, Tenable recommends reviewing the release notes for all skipped versions to learn about new features and bug fixes.
