Tutorial: Azure AD SSO integration with HackerOne

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

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

Prerequisites

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.
  • HackerOne single sign-on (SSO) enabled subscription.

Scenario description

In this tutorial, you configure and test Azure AD single sign-on in a test environment.

  • HackerOne supports SP initiated SSO.
  • HackerOne supports Just In Time user provisioning.

Note

Identifier of this application is a fixed string value so only one instance can be configured in one tenant.

To configure the integration of HackerOne into Azure AD, you need to add HackerOne 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 HackerOne in the search box.
  6. Select HackerOne 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 HackerOne

Configure and test Azure AD SSO with HackerOne 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 HackerOne.

To configure and test Azure AD SSO with HackerOne, 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 HackerOne SSO - to configure the single sign-on settings on application side.
    1. Create HackerOne test user - to have a counterpart of B.Simon in HackerOne 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 HackerOne application integration page, find the Manage section and select single sign-on.

Create HackerOne test user

In this section, a user called Britta Simon is created in HackerOne. HackerOne supports just-in-time user provisioning, which is enabled by default. There is no action item for you in this section. If a user doesn't already exist in HackerOne, a new one is created after authentication.

Test SSO

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

  • Click on Test this application in Azure portal. This will redirect to HackerOne Sign-on URL where you can initiate the login flow.

  • Go to HackerOne Sign-on URL directly and initiate the login flow from there.

  • You can use Microsoft My Apps. When you click the HackerOne tile in the My Apps, this will redirect to HackerOne Sign-on URL. For more information about the My Apps, see Introduction to the My Apps.

Once you configure HackerOne 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.
