Duo Single Sign-On for Cisco Umbrella

Last Updated: October 6th, 2020

Add two-factor authentication and flexible security policies to Cisco Umbrella SSO logins with Duo Single-Sign On, our cloud-hosted SAML 2.0 identity provider, complete with inline self-service enrollment and Duo Prompt.


As business applications move from on-premises to cloud hosted solutions, users experience password fatigue due to disparate logons for different applications. Single sign-on (SSO) technologies seek to unify identities across systems and reduce the number of different credentials a user has to remember or input to gain access to resources.

While SSO is convenient for users, it presents new security challenges. If a user's primary password is compromised, attackers may be able to gain access to multiple resources. In addition, as sensitive information makes its way to cloud-hosted services it is even more important to secure access by implementing two-factor authentication.

About Duo Single Sign-On

Duo Single Sign-On is our cloud-hosted SSO product which layers Duo's strong authentication and flexible policy engine on top of Cisco Umbrella logins using the Security Assertion Markup Language (SAML) 2.0 authentication standard. Duo Single Sign-On acts as an identity provider (IdP), authenticating your users using existing on-premises Active Directory (AD) or any SAML 2.0 IdP and prompting for two-factor authentication before permitting access to Cisco Umbrella.

Duo Single Sign-On is available in Duo Beyond, Duo Access, and Duo MFA plans, which also include the ability to define policies that enforce unique controls for each individual SSO application. For example, you can require that Salesforce users complete two-factor authentication at every login, but only once every seven days when accessing Cisco Umbrella. Duo checks the user, device, and network against an application's policy before allowing access to the application.

Configure Single Sign-On

Before configuring Cisco Umbrella you'll first need to enable Duo Single Sign-On for your Duo account and configure a working authentication source.

Once you have your SSO authentication source working, continue to the next step of creating the Cisco Umbrella application in Duo.

Create the Cisco Umbrella Application in Duo

  1. Log on to the Duo Admin Panel and navigate to Applications.

  2. Click Protect an Application and locate the entry for Cisco Umbrella with a protection type of "2FA with SSO hosted by Duo (Single Sign-On)" in the applications list. Click Protect to the far-right to start configuring Cisco Umbrella. See Protecting Applications for more information about protecting applications in Duo and additional application options. You'll need the information on the Cisco Umbrella page under Downloads later.

  3. Cisco Umbrella uses the Mail attribute when authenticating. We've mapped the <Email Address> bridge attribute to Duo Single Sign-On supported authentication source attributes as follows:

    Bridge Attribute Active Directory SAML IdP
    <Email Address> mail Email

    If you are using a non-standard email attribute for your authentication source, check the Custom attributes box and enter the name of the attribute you wish to use instead.

  4. You can adjust additional settings for your new SAML application at this time — like changing the application's name from the default value, enabling self-service, or assigning a group policy.

  5. Scroll to the bottom of the page and click the Save button.

Duo Universal Prompt

Duo's next-generation authentication experience, the Universal Prompt, is coming to web-based applications that display the current Duo Prompt in browsers.

Migration to Universal Prompt for your Cisco Umbrella application is a two-step process:

  • Update the Cisco Umbrella application to support the Universal Prompt.
  • Enable the Universal Prompt experience for users of that Cisco Umbrella application (when the Universal Prompt becomes available)

We've already updated the Duo Cisco Umbrella application to support the Universal Prompt when it's ready, so there's no action required on your part to update. The "Universal Prompt" section of this application's details page in the Admin Panel reflects this status today as "New Prompt Ready".

Universal Prompt Info - Application Updated

When the Universal Prompt becomes available, you'll return here to activate it for users of this application.

Click the See Update Progress link to view the Universal Prompt Update Progress report. This report shows the update availability and migration progress for all your Duo applications in-scope for Universal Prompt support.

Read the Universal Prompt Update Guide for more information about the update process to support the new prompt, and watch the Duo Blog for future updates about the Duo Universal Prompt.

Configure Cisco Umbrella SSO

Configure Duo Single Sign-On as a new SSO provider in Cisco Umbrella.

  1. Log on to Cisco Umbrella as an administrative user and navigate to AdminAuthentication and under "SAML Dashboard User Configuration" click on Enable SAML.

  2. When asked "Which SAML based SSO Service would you like to use?" click Other and then click Next.

  3. On the Umbrella Metadata page click Next.

  4. Click Download XML next to "XML file" under Downloads on your Cisco Umbrella application's details page in the Duo Admin Panel to download the Duo Single Sign-On XML metadata file. On the Cisco Umbrella Upload and Verify Other Metadata page under "XML File Upload" click Or select a file... and select the XML metadata file.

  5. Click Test Configuration. A pop-up will appear and redirect to the Duo Single Sign-On login page. Enter your primary directory logon information and approve Duo two-factor authentication. You will see a "Success" message. Close this window, return to the configuration page, and click Next

Log in with SSO

Navigate to the Cisco Umbrella login page and click the Single sign on link. Enter your email address and click Sign In. This redirects to the Duo Single Sign-On login page. Enter your primary directory logon information, approve Duo two-factor authentication, and get redirected back to the Cisco Umbrella site after authenticating.

Duo Single Sign-On Login and Authentication Prompt

Congratulations! Your Cisco Umbrella users now authenticate using Duo Single Sign-On.

Enable Remembered Devices

To minimize additional Duo two-factor prompts when switching between Cisco Umbrella and your other Duo Single Sign-On SAML applications, be sure to apply a shared "Remembered Devices" policy to your SAML applications.
