Managing identities and access has become one of the most critical aspects of cybersecurity and user experience. However, not all identity management systems are created equal.
To truly understand how organizations protect their resources and serve their users, we need to explore two fundamental approaches: Identity and Access Management (IAM) and Customer Identity and Access Management (CIAM).
