Configure Contrast Security SSO

To configure single sign-on on Contrast Security side, you need to send the App Federation Metadata Url to Contrast Security support team. They set this setting to have the SAML SSO connection set properly on both sides.

Create Contrast Security test user

In this section, a user called Britta Simon is created in Contrast Security. Contrast Security 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 Contrast Security, a new one is created after authentication.

Test SSO

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

SP initiated:

  • Click on Test this application, this will redirect to Contrast Security Sign on URL where you can initiate the login flow.

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

IDP initiated:

  • Click on Test this application, and you should be automatically signed in to the Contrast Security for which you set up the SSO.

You can also use Microsoft My Apps to test the application in any mode. When you click the Contrast Security tile in the My Apps, if configured in SP mode you would be redirected to the application sign on page for initiating the login flow and if configured in IDP mode, you should be automatically signed in to the Contrast Security for which you set up the SSO. For more information about the My Apps, see Introduction to the My Apps.

Once you configure Contrast Security 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.
