Tenable One: Microsoft Entra ID IdP

One of the most common IdPs used to configure SAML with Tenable One is Microsoft Entra ID. The following steps guide you through the configuration process from start to finish.

Manual configuration requires the following:

  • Reply URL: A custom URL provided by Tenable in the following format:

    https://cloud.tenable.com/saml/login/PLACEHOLDER

  • Identifier (Entity ID): A custom ID provided by Tenable during SAML configuration in the following format:

    TENABLE_IO_PLACEHOLDER

  • A certificate within the SAML metadata object that matches the data originally sent to Tenable.

    Note: Tenable does not support the use of multiple certificates and only extracts the first certificate from the metadata object. If the object includes multiple certificates, you must specify which certificate to use if it is not the first one listed.

Optional: Configure One or More User Groups to Automatically Add a User upon SAML Login

User groups allow you to manage user permissions for various resources in Tenable One. When you assign users to a group, the users inherit the permissions assigned to the group. When you enable the Managed by SAML option for a user group, Tenable One allows you to automatically add any user that logs in via SAML to that group.

Important: For this option to work successfully, you must also configure the related group claim within your IdP. View the final IdP configuration steps for more information.

Before you begin:

Ensure you've enabled the Group Management Enabled toggle when configuring the SAML settings within Tenable One.

To enable the Managed by SAML option:

  1. In Tenable Vulnerability Management, in the upper-left corner, click the button.

Microsoft Entra ID: Configure Final Application and Upload Metadata

Now that you have downloaded the completed metadata file, you can upload that file to your Tenable application in Microsoft Entra ID.

  1. In your browser, navigate to the Azure Admin portal.

  2. In the navigation menu, navigate to All services > Enterprise Applications.

    The application gallery appears.

  3. Select the newly created application.

    The application overview appears.

  4. In the left navigation menu, click Manage > Single sign-on.

    The SAML-based Sign-on options appear.

  5. Click Upload Metadata file.

  6. In your file manager, select the Service Provider metadata.xml file that you downloaded from Tenable Vulnerability Management.

    Microsoft Entra ID imports the metadata from the file, including the Reply URL and Identifier specific to the SAML configuration.

  7. Click Save.

    Microsoft Entra ID saves your changes to the permanent application, and your SAML configuration is ready for use.

Optional: Finalize Configuration for Managed by SAML Group Option

If you configured the Managed by SAML option to automatically add any user that logs in via SAML to a user group, then you must configure a related group claim within the Microsoft Entra ID IdP.

To configure the IdP group claim:

  1. In your browser, navigate to the Azure Admin portal.

  2. In the navigation menu, navigate to All services > Enterprise Applications.

    The application gallery appears.

  3. Select the newly created application.

    The application overview appears.

  4. In the left navigation menu, click Manage > Single sign-on.

    The SAML-based Sign-on options appear.

  5. On the Attributes & Claims tile, click the Edit button.

    The Attributes & Claims page appears.

  6. Click Add a group claim.

    The Group Claims pane appears.

  7. Do one of the following:

      1. Select the Groups assigned to the application radio button.

      2. In the Source attribute drop-down, select the best option based on your environment, such as Group ID.

        Tip: The source attribute options available vary based on the selected groups. For example, the Group ID source attribute does not divulge a group’s Display Name (for example, Developers), but rather its Object ID (for example, 11111111-2222-3333-4444-555555555555). As such, if you select Group ID, you must ensure that the name of the associated group configured within Tenable One matches the ID of the group listed within the Microsoft Entra ID portal (Home > Groups > All Groups).



        Where available, you may instead choose to select Cloud-only group display names. If you sync with Active Directory, there are other available options within the Source Attribute drop-down.

        Alternatively, you could create a custom claim using groups as the claim name and setting the group’s readable name (for example, Developers) as the source attribute.

        This allows mapping to readable names within Tenable One, instead of IDs, while not accounting for groups assigned to an application within Microsoft Entra ID. To maximize your configurations and make sure that you’re familiar with all caveats, see Configure group claims for applications by using Microsoft Entra ID.

      1. Select the radio button for the option that best suits your environment, for example, Security Groups.

      2. In the Source attribute drop-down, select the best option based on your environment, such as Group ID.

        Tip: The source attribute options available vary based on the selected groups. For example, the Group ID source attribute does not divulge a group’s Display Name (for example, Developers), but rather its Object ID (for example, 11111111-2222-3333-4444-555555555555). As such, if you select Group ID, you must ensure that the name of the associated group configured within Tenable One matches the ID of the group listed within the Microsoft Entra ID portal (Home > Groups > All Groups).



        Where available, you may instead choose to select Cloud-only group display names. If you sync with Active Directory, there are other available options within the Source Attribute drop-down.

        To maximize your configurations and make sure that you’re familiar with all caveats, see Configure group claims for applications by using Microsoft Entra ID.

  8. Select Advanced > Customize the name of the group claim check box.

  9. In the Name text box, type groups.

  10. Click Save. Any time a user logs in via your SAML configuration, Tenable One automatically adds them to the specified user group in Tenable One.

Optional: Configure Managed by SAML Role Option

Roles allow you to manage privileges for major functions in Tenable One and control which Tenable One resources users can access. If you toggled on the SAML configuration options IdP Assigns User Role at Provisioning and/or IdP Resets User Role at Each Login (to automatically add and/or assign any user that logs in via SAML to a user role), then you must complete the following steps in Microsoft Entra ID:

To configure Managed by SAML role option:

  1. In your browser, navigate to the Azure Admin portal.

  2. In the navigation menu, navigate to All services > Enterprise Applications.

    The application gallery appears.

  3. Select the newly created application.

    The application overview appears.

  4. In the left navigation menu, click Manage > Single sign-on.

    The SAML-based Sign-on options appear.

  5. On the Attributes & Claims tile, click the Edit button.

    The Attributes & Claims page appears.

  6. Do one of the following:

      1. Click Add new claim.

        The Manage claim pane appears.

      2. In the Name text box, type userRoleUuid.

      3. In the Source attribute text box, type the UUID of the Tenable user role.

        Tip: Tenable user role UUIDs can be found in Tenable Vulnerability Management, in the Settings > Access Control > Roles table.

    • If each user should be assigned their own unique role, you can define their role with user attributes. Based on your level of experience with Microsoft Entra ID and Microsoft Graph, you may be most comfortable with one option or another. Some examples include:

      • Leverage extension attribute: Microsoft Entra ID offers a set of 15 extension attributes with predefined names, which can be edited with Microsoft Graph. You can learn to add and read these extension attributes by visiting Add Custom data to Resources Using Extensions.

        1. Using Microsoft Graph, identify an available (unused) extension attribute.

        2. For each user within the organization, update the selected extension attribute with the UUID of the Tenable user role.

          Tip: Tenable user role UUIDs can be found in Tenable Vulnerability Management, in the Settings > Access Control > Roles table.

          1. For example, you can modify the attribute using the PATCH method:

          2. Then confirm the change using the GET method:

        3. Within the Attributes & Claims page of the newly created app, click Add new claim.

          The Manage claim pane appears.

        4. In the Name text box, type userRoleUuid.

        5. In the Source attribute text box, find and select the appropriate extension attribute (for example, user.extensionattribute1).

      • Leverage existing attributes: You may opt to modify an existing and available (unused) attribute (for example, Fax Number). This can be useful for testing, small scale deployments, or until extension attributes can be leveraged.

        1. Navigate to Home > Users.

        2. For each user in scope, select Properties.

          The Properties pane appears.

        3. Select an available existing attribute and edit the value with the UUID of the Tenable user role.

          Tip: Tenable user role UUIDs can be found in Tenable Vulnerability Management, in the Settings > Access Control > Roles table.

        4. Within the Attributes & Claims page of the newly created app, click Add new claim.

          The Manage claim pane appears.

        5. In the Name text box, type userRoleUuid.

        6. In the Source attribute text box, and and select the appropriate extension attribute (for example, user.facsimiletelephonenumber).

    • If users of a specific user group within Microsoft Entra ID should all be assigned the same role within Tenable One, (for example, Administrators), then you can leverage their existing group membership:

      1. Click Add new claim.

        The Manage claim pane appears.

      2. In the Name text box, type userRoleUuid.

      3. For each required role:

        1. Under Claim conditions, in the User type drop-down, select the best option based on your environment, such as Members.

        2. Click Select groups and then select the relevant user group.

        3. In the Source drop-down, select Attribute.

      4. In the Value text box, type the UUID of the Tenable user role.

        Tip: Tenable user role UUIDs can be found in Tenable Vulnerability Management, in the Settings > Access Control > Roles table.

  7. Click Save. Any time a user logs in via your SAML configuration, Tenable One automatically adds them the specified user role in Tenable One.

    Tip: Alternatively, you can create separate applications in Microsoft Entra ID: one for each role and/or each user group (along with separate SAML integrations within Tenable One), where each user is assigned to an application based on their expected role/group mapping.
