Integrate Tableau with Zero Trust Network Access

In this topic, you will find general instructions on how to integrate Tableau with Portnox™ Zero Trust Network Access.

Create a Portnox Cloud application configuration

In this step, you will create a configuration in Portnox Cloud that will contain all the information necessary to integrate with Tableau.

  1. In a new tab of your browser, open your Portnox Cloud account by accessing the following URL: https://clear.portnox.com/

    From now on, we will call this tab the Portnox tab.

  2. In the Cloud portal top menu, click on the Zero Trust Resources option.

  3. On the Resources screen, click on the Create resource button.

    1. In the What type of resource is this? section, select the SSO web application option.
    2. In the Authentication protocol section, select the SAML option.
    3. Click on the Next button.

  4. Optional: If you have more than one SAML identity provider configured, select the identity provider in the Select an identity provider to use for this resource section.
  5. In the Resource details section, enter a Resource name and optionally a Description.

    In this example, we used the name Tableau for the new application configuration but you can use any name you like.

  6. Keep this browser tab open. You will need it later.

Open your Tableau SAML SSO settings

In this section, you will access your Tableau administrative interface and find the SAML single sign-on (SSO) settings.

  1. In another tab of your browser, open your Tableau dashboard by accessing the following URL: https://online.tableau.com/ and signing in to your account.

    From now on, we will call this tab the Tableau tab.

  3. In the Select authentication type drop-down menu, select the SAML option.

Copy configuration values from the Tableau tab to the Portnox tab

In this section, you will copy the values displayed in the Tableau SAML SSO setup section and paste them in the relevant fields in Portnox Cloud.

  1. In the Tableau tab, in the 1. Export metadata from Tableau Cloud step, select the value of the Tableau Cloud entity ID field and use the operating system shortcut to copy it to the clipboard.

  2. In the Portnox tab, in the Resource properties section, click on the empty field under the Entity ID / Service Provider Entity URL heading and paste the value copied from Tableau.

  3. In the Tableau tab, select the value of the Tableau Cloud ACS URL field and use the operating system shortcut to copy it to the clipboard.

  1. Finalize the configuration in the Portnox tab.
    1. Optional: Click on the Next button, and in the Policy enforcement section, in the Device risk assessment section, change the setting to Override with custom policy and then select a risk assessment policy if you want to assess risk with this application using a custom risk assessment policy, and in the Access control section, change the setting to Override with custom policy and then select an access control policy if you want to control access to this application using a custom access control policy.
    2. Scroll all the way down to the end of the page, and then click on the Add resource button.

  2. Finalize the configuration in the Tableau tab.
    1. Click on the Save Changes button under step 6.
