Manage the Tenable Core Server Certificate

When a user initially signs in to Tenable Core, a default self-signed security certificate is installed. This default certificate is an auto-generated placeholder for the custom certificate; it is not signed by a recognized certificate authority and, if not updated with a valid certificate, will cause security warnings to display in the browser.

Replacing this certificate with a custom certificate allows the user to access Tenable Core securely without receiving error messages. A user can also replace these custom certificates as needed or remove the custom certificate entirely, which will then be replaced with a new self-signed auto-generated certificate.

Before you begin:

  • Make sure you have the custom security certificate and server key from your organization (.DER, .PEM, or .CRT are all accepted file extensions).
  • Make sure you're in the left navigation pane for the appropriate server.

    Note: The left navigation pane will list system pages vertically. Click the host navigation host navigation button in the expanding panel to navigate to the left navigation pane from another section.
