Manage the Server Certificate

When you first deploy Tenable Core, Tenable provides a default server certificate for accessing the Tenable Core interface.

Tip: By default, Tenable Core uses separate certificates for Tenable Core and OT Security. For information about the OT Security application certificate, see the OT Security Documentation.

Note: The default certificate is not signed by a recognized certificate authority (CA). If your browser reports that the Tenable Core server certificate is untrusted, Tenable recommends uploading a custom server certificate signed by a trusted certificate authority (CA) for Tenable Core use. For more information, see Upload a Custom Server Certificate. Alternatively, you can download the Tenable-provided CA certificate (cacert.pem) for your server certificate and upload it to your browser.

If you upload a custom server certificate signed by a custom CA, you must also provide certificates in the chain to validate your custom server certificate.
