Add Zero Trust Network Access to the Okta Platform as an authentication factor

In this topic, you will find instructions on how to add Portnox™ Zero Trust Network Access to the Okta Platform as an authentication factor.

Prerequisites:

  • You must first integrate your Portnox Cloud instance with your Okta Workforce Identity repository as an authentication provider. For more information, see the following topic: Integrate with Okta Wokforce Identity.

When Portnox ZTNA is added as an authentication factor to Okta, every time you access a web application using Okta single sign-on (SSO), you are verified by Portnox ZTNA instead of only receiving Okta Verify prompts. This adds all the benefits of ZTNA, such as device compliance checks.

This setup lets you configure the integration once and then use it with any app that supports Okta SSO. You do not need to configure Okta as an identity provider for each app individually. However, this also gives you less control over specific apps, since you cannot apply different configurations in Portnox Cloud (for example, policies).

Note: This setup does not use Portnox as an identity provider. Instead, it relies only on resource configuration in ZTNA.

Create a new resource configuration in Portnox Cloud

In this section, you will create a new resource configuration in Portnox Cloud, which will let you add Portnox ZTNA as a factor to the Okta Platform.

  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.
