Identity and Access Management (IAM) is the discipline that enables the right individuals or non-person entities to access the right resources at the right times for the right reasons. Done right, it aligns access rights with the needs of the business, guaranteeing that members of the organization obtain the permissions they need when they need them. The IDAM market is segmented into Access Management / Single Sign-On (SSO) / Privileged Access Management, Identity Governance and Administration (IGA), and Internet of Things (IoT)-driven IAM solutions.”]
