Enhancing Security and Efficiency: Azure AD and SSO Implementation in Hybrid Systems

Organization

Our client is a prominent nonprofit organization supporting over 55,000 churches and faith-based organizations across North America. With a history spanning more than four decades, the organization delivers integrated solutions for people and donor management, digital giving, websites, communication, event planning, and employee/volunteer background screenings.

Scale of Operations:

• Serves more than 1 million end-users, including church staff, volunteers, and donors.
• Manages over 500 applications across on-premises and cloud environments.
• Supports thousands of daily logins, emphasizing the need for secure, efficient identity management.

CHALLENGE

The organization sought to enhance its identity and access management capabilities by adopting Azure Active Directory (AD) and implementing Single Sign-On (SSO) across its on-premises and cloud-based applications. The project posed several challenges:

• Hybrid Identity Complexity: Managing both on-premises and cloud-based identities during migration required a hybrid solution. Ensuring no credentials were lost or compromised during the transition was critical.
• Application Compatibility: Legacy applications that did not support modern authentication protocols, such as SAML or OAuth, required custom configurations and additional effort to integrate with Azure AD.
• Security and Compliance: As the organization manages sensitive user data, maintaining compliance with data protection regulations (e.g., GDPR, CCPA) and implementing robust security measures were non-negotiable.
• Streamlined Access: The goal was to enable seamless, secure access to resources across a variety of devices and locations while maintaining role-based access controls.
• User and Group Management: Simplifying user lifecycle management and ensuring access was consistently aligned with organizational roles demanded automated solutions.

SOLUTION

XTIVIA collaborated with the organization to design and implement an Azure AD and SSO solution tailored to their unique requirements. The solution addressed the key challenges while ensuring scalability and security for future needs.

Azure AD Integration

• Hybrid Environment Setup: XTIVIA configured Azure AD Connect to synchronize the client’s on-premises Active Directory (AD) with Azure AD. This hybrid setup enabled a smooth transition phase while ensuring continuity for users during migration.
• Identity Federation: Federated Azure AD with Microsoft 365 and other enterprise applications. Password synchronization between on-prem and cloud environments allowed users to maintain a unified login experience.
• Dynamic Group Management: The directory structure was reorganized in Azure to create dynamic groups aligned with departments, roles, and permissions. These groups synchronized with existing on-prem AD groups to maintain consistency and improve management.

Single Sign-On (SSO) Implementation

• Enterprise Applications Configuration: Configured SSO for various cloud-based applications, including Salesforce, GitHub, Microsoft 365, and Monday.com. XTIVIA utilized SAML, OAuth, and OpenID Connect protocols based on each application’s requirements.
• Custom Application Integrations: Created custom integrations for in-house applications using Azure AD’s App Registrations, ensuring legacy applications could securely use modern authentication protocols like OAuth 2.0 or SAML 2.0.
• Unified Login Experience: Employees accessed integrated applications through the Azure AD MyApps portal, which provided a user-friendly dashboard for seamless navigation.

Azure AD Integration Security Enhancements

• Multi-Factor Authentication (MFA): XTIVIA enabled Azure MFA for all users, adding a second layer of security via mobile app notifications, phone calls, or text messages. This mitigated risks associated with compromised passwords.
• Conditional Access Policies: Conditional Access was configured to enforce security requirements based on context. For instance:
  • Users accessing sensitive data from untrusted networks were required to verify their identity with MFA.
  • Device compliance checks ensured that only secure, managed devices could access corporate resources.

Azure AD Integration User and Group Management

• Automated User Provisioning: Integrated Azure AD Identity Governance with the client’s HR system to automate user account creation, updates, and deactivations. This eliminated manual processes, ensuring users’ access remained aligned with their roles.
• Role-Based Access Control (RBAC): XTIVIA leveraged Azure AD’s RBAC to grant permissions tailored to job roles, ensuring sensitive resources were accessible only to authorized users. This streamlined user management and improved security.

Comprehensive Testing and Deployment Support

• Compatibility Testing: XTIVIA ensured the solution worked across various devices and browsers, validating cross-platform compatibility.
  
• Deployment Assistance: Delivered a detailed checklist and implementation plan to streamline the deployment process.
  
• Post-Implementation Support: XTIVIA provided ongoing monitoring and support to address issues promptly and ensure optimal system performance.

This comprehensive solution not only met the client’s immediate needs but also established a scalable and secure framework to support future growth and innovation.

BUSINESS RESULT

The Azure AD and SSO implementation delivered measurable benefits for the organization:
