Upload an SSL Certificate for the Tenable.io Interface

Tenable.io on-prem supports uploading an SSL certificate for secure access to the Tenable.io interface. You can reuse the certificates you used for the on-prem configuration interface, or upload new certificates. For more information, see SSL Certificates.

Before you begin:

To upload an SSL certificate for secure connections to the Tenable.io interface:

  1. Log in to the on-prem configuration interface.
  2. Click SSL/TLS Certificates.

    The SSL/TLS Certificates page appears.

  3. Click the Tenable.io On-prem Certificate tab.

  4. (Optional) If you want to remove the current certificates, click Reset Server Certificates.

    Note: If the Reuse System Certificate check box is selected, you must reset your server certificates on the System Certificate tab, as described in Upload an SSL Certificate for the On-prem Configuration Interface.

    The system removes your current certificates.

  5. (Optional) If you want to reuse the same certificates you configured for the on-prem configuration interface, confirm the Reuse System Certificate check box is selected.

    If you want to upload different certificates, deselect the Reuse System Certificate check box and continue uploading certificates:

    1. Next to Server Certificate, click Choose File.
    2. Browse to the PEM-encoded, DER-encoded, or CRT-encoded CA certificate that you want to upload.
    3. Next to Server Key, click Choose File.
    4. Browse to the PEM-encoded, DER-encoded, or CRT-encoded server key that you want to upload.
    5. (Optional) If your server certificate requires an intermediate certificate, next to Intermediate Certificate, click Choose File and browse to the PEM-encoded, DER-encoded, or CRT-encoded certificate that you want to upload.

    6. (Optional) If your certificates are signed by a custom certificate authority, next to Custom Root CA Certificate, click Choose File and browse to the PEM-encoded, DER-encoded, or CRT-encoded certificate that you want to upload.
    7. Click Install Server Certificates.

      The upload begins. You cannot access the Tenable.io interface for 15 minutes during the upload.
