Tutorial: Azure Active Directory single sign-on (SSO) integration with PerimeterX

In this tutorial, you'll learn how to integrate PerimeterX with Azure Active Directory (Azure AD). When you integrate PerimeterX with Azure AD, you can:

  • Control in Azure AD who has access to PerimeterX.
  • Enable your users to be automatically signed-in to PerimeterX with their Azure AD accounts.
  • Manage your accounts in one central location - the Azure portal.


To get started, you need the following items:

  • An Azure AD subscription. If you don't have a subscription, you can get a free account.
  • PerimeterX single sign-on (SSO) enabled subscription.

Scenario description

In this tutorial, you configure and test Azure AD SSO in a test environment.

  • PerimeterX supports IDP initiated SSO

To configure the integration of PerimeterX into Azure AD, you need to add PerimeterX from the gallery to your list of managed SaaS apps.

  1. Sign in to the Azure portal using either a work or school account, or a personal Microsoft account.
  2. On the left navigation pane, select the Azure Active Directory service.
  3. Navigate to Enterprise Applications and then select All Applications.
  4. To add new application, select New application.
  5. In the Add from the gallery section, type PerimeterX in the search box.
  6. Select PerimeterX from results panel and then add the app. Wait a few seconds while the app is added to your tenant.

Alternatively, you can also use the Enterprise App Configuration Wizard. In this wizard, you can add an application to your tenant, add users/groups to the app, assign roles, as well as walk through the SSO configuration as well. Learn more about Microsoft 365 wizards.

Configure and test Azure AD SSO for PerimeterX

Configure and test Azure AD SSO with PerimeterX using a test user called B.Simon. For SSO to work, you need to establish a link relationship between an Azure AD user and the related user in PerimeterX.

To configure and test Azure AD SSO with PerimeterX, perform the following steps:

  1. Configure Azure AD SSO - to enable your users to use this feature.
    1. Create an Azure AD test user - to test Azure AD single sign-on with B.Simon.
    2. Assign the Azure AD test user - to enable B.Simon to use Azure AD single sign-on.
  2. Configure PerimeterX SSO - to configure the single sign-on settings on application side.
    1. Create PerimeterX test user - to have a counterpart of B.Simon in PerimeterX that is linked to the Azure AD representation of user.
  3. Test SSO - to verify whether the configuration works.

Configure Azure AD SSO

Follow these steps to enable Azure AD SSO in the Azure portal.

  1. In the Azure portal, on the PerimeterX application integration page, find the Manage section and select single sign-on.

  2. On the Select a single sign-on method page, select SAML.

  3. On the Set up single sign-on with SAML page, click the edit/pen icon for Basic SAML Configuration to edit the settings.

    Edit Basic SAML Configuration

  4. On the Basic SAML Configuration section, the application is pre-configured and the necessary URLs are already pre-populated with Azure. The user needs to save the configuration by clicking the Save button.

  5. PerimeterX application expects the SAML assertions in a specific format, which requires you to add custom attribute mappings to your SAML token attributes configuration. The following screenshot shows the list of default attributes.


  6. In addition to above, PerimeterX application expects few more attributes to be passed back in SAML response which are shown below. These attributes are also pre populated but you can review them as per your requirements.

    Name Source Attribute
    firstName user.givenname
    lastName user.surname
  7. On the Set up single sign-on with SAML page, in the SAML Signing Certificate section, find Certificate (Base64) and select Download to download the certificate and save it on your computer.

  8. On the Set up PerimeterX section, copy the appropriate URL(s) based on your requirement.

    Copy configuration URLs

Create an Azure AD test user

In this section, you'll create a test user in the Azure portal called B.Simon.

  1. From the left pane in the Azure portal, select Azure Active Directory, select Users, and then select All users.
  2. Select New user at the top of the screen.
  3. In the User properties, follow these steps:
    1. In the Name field, enter B.Simon.
    2. In the User name field, enter the username@companydomain.extension. For example, B.Simon@contoso.com.
    3. Select the Show password check box, and then write down the value that's displayed in the Password box.
    4. Click Create.

Assign the Azure AD test user

In this section, you'll enable B.Simon to use Azure single sign-on by granting access to PerimeterX.

  1. In the Azure portal, select Enterprise Applications, and then select All applications.
  2. In the applications list, select PerimeterX.
  3. In the app's overview page, find the Manage section and select Users and groups.
  4. Select Add user, then select Users and groups in the Add Assignment dialog.
  5. In the Users and groups dialog, select B.Simon from the Users list, then click the Select button at the bottom of the screen.
  6. If you are expecting a role to be assigned to the users, you can select it from the Select a role dropdown. If no role has been set up for this app, you see "Default Access" role selected.
  7. In the Add Assignment dialog, click the Assign button.

Configure PerimeterX SSO

  1. Login to your PerimeterX console with Admin permissions.

  2. Navigate to Admin > ACCOUNTS

  3. Click Edit

  4. In the Edit Account dialog, perform the following steps.

    PerimeterX sso edit account

    a. Check Enable Single Sign-On (SSO)

    b. Select Azure SAML.

    c. In the SAML Endpoint textbox, paste the Login URL value you copied the Azure portal.

    d. In the Issuer textbox, Paste the Azure AD Identifier value copied from the Azure portal.

    e. Open the downloaded Certificate (Base64) from the Azure portal into Notepad and paste the content into the X.509 Certificate textbox.

    f. Click on Save Changes

Create PerimeterX test user

Please refer to the PerimeterX Managing Users Guide for instructions on how to create the PerimeterX test user.

Test SSO

In this section, you test your Azure AD single sign-on configuration with following options.

  1. Click on Test this application in Azure portal and you should be automatically signed in to the PerimeterX for which you set up the SSO

  2. You can use Microsoft Access Panel. When you click the PerimeterX tile in the Access Panel, you should be automatically signed in to the PerimeterX for which you set up the SSO. For more information about the Access Panel, see Introduction to the Access Panel.

Next Steps

Once you configure PerimeterX you can enforce session control, which protects exfiltration and infiltration of your organization’s sensitive data in real time. Session control extends from Conditional Access. Learn how to enforce session control with Microsoft Defender for Cloud Apps.
