This article delves into why companies should adopt open-source CIAM solutions, compares some of the leading options, and highlights how they keep customer data safe and secure.

Understanding CIAM and Its Importance

Customer Identity and Access Management (CIAM) is a framework that enables organizations to securely capture and manage customer identity and profile data. It governs how customers access applications and services, ensuring that only authorized users can interact with sensitive information.

Key functions of CIAM include:

• User Authentication: Verifying user identities through credentials like passwords, biometrics, or multi-factor authentication.
• Authorization: Granting or restricting access to resources based on user roles and permissions.
• Profile Management: Handling customer data, preferences, and consent for data usage.
• Security and Compliance: Ensuring adherence to regulations like GDPR, CCPA, and HIPAA.

The importance of CIAM lies in its ability to provide a seamless and secure user experience while safeguarding sensitive customer data from unauthorized access and cyber threats.

The Risks of Third-Party Vendors

Relying on proprietary CIAM solutions from third-party vendors may seem convenient, but it introduces several risks:
