Authentication & Access Control encompasses technologies and processes that verify user identities and regulate permissions to digital resources within an organization. This category addresses the foundational requirement of ensuring that only authorized individuals or systems can access specific data, applications, or network assets. Core capabilities include user authentication methods such as passwords, biometrics, multi-factor authentication, and single sign-on, as well as access control mechanisms like role-based access control (RBAC), attribute-based access control (ABAC), and policy enforcement. These solutions often integrate with directory services and identity providers to centralize and streamline identity management across diverse environments. Typical users of authentication and access control solutions include IT administrators, security teams, and compliance officers in organizations of all sizes. Their primary objectives are to reduce unauthorized access risks, support regulatory compliance, and manage user privileges efficiently. This category is distinct from broader identity and access management (IAM) solutions, which may also cover identity lifecycle management, provisioning, and governance.
