IAM – What Is It? Fundamentals of Identity & Access Management Systems

Identity & Access Management is the fundamental security framework that defines and controls who has access to which digital resources, when that access is granted, and under what specific conditions. IAM is far more than just a technical solution – it is the strategic nervous system of modern organizations, connecting security, productivity, and compliance while serving as an enabler for digital transformation.
