Configure AWS SSO with Access for SaaS

This guide covers how to configure AWS SSO with Access for SaaS. Cloudflare Access for SaaS allows you to layer additional network and device posture policies on top of existing identity authentication from your identity provider. In this example, we are using Okta as an identity provider, but any supported identity provider can be leveraged.

​​ Prerequisites

  • A Zero Trust account
  • An integrated IdP
  • Admin access to an AWS account

​​ 1. Configure AWS

  1. In the AWS admin panel, search for SSO.

  2. Add AWS Single Sign on to your AWS account.

  3. Select Choose an identity source.

  4. Change the identity source to External Identity provider.

  5. Select Show individual metadata values. These will be the fields that are added to the Cloudflare Access for SaaS app.

  6. Copy the AWS SSO ACS URL.

​​ 2. Configure Cloudflare

  1. In a separate tab or window, open Zero Trust and go to Access > Applications.

  2. Select SaaS as the application type to begin creating a SaaS application.

  3. Copy the following fields from your AWS account and input them in the Zero Trust application configuration:

    AWS value Cloudflare value
    AWS SSO ACS URL Assertion Consumer Service URL
    AWS SSO Issuer URL Entity ID

    The Name ID Format must be set to: Email.

  4. (Optional) Additional Attribute Statements can be passed from your IdP to AWS SSO. More information about AWS Attribute mapping can be found at Attribute mappings - AWS Single Sign-On.

  5. Copy the Cloudflare IdP metadata values and save them for the Final AWS configuration.

  6. Select Next.

  7. Now create an Access policy to determine who has access to your application.

  8. Save your policy and return to the AWS SSO dashboard.

​​ 3. Complete the AWS configuration

  1. Paste the Cloudflare IdP metadata into your AWS account with these mappings:

    Cloudflare value AWS value
    SSO Endpoint IdP Sign-in URL
    Access Entity ID IdP Issuer URL
    Public Key IdP Certificate

  2. Select Next: Review.

  3. Set Provisioning to Manual.
