Which feature of Mimecast allows administrators to manage user access?

The feature that enables administrators to manage user access is Role-Based Access Control. This system assigns specific roles to users based on their job functions, allowing for customized access levels to various parts of the Mimecast platform. By defining roles, administrators ensure that users have the appropriate permissions required to perform their duties while also maintaining security protocols.

Role-Based Access Control enhances security by limiting user access to only those features and data necessary for their work, thereby reducing the risk of unauthorized access or accidental changes to critical settings. With this approach, organizations can effectively manage user permissions centrally, streamline user management, and ensure compliance with internal or external regulations regarding data protection and user access.

In contrast, user permissions on their own may not provide the robust structure that role-based systems offer. Content filtering pertains to managing email content rather than user access, and service monitoring focuses on tracking the performance and status of Mimecast services rather than handling user roles and permissions. Thus, Role-Based Access Control is the correct choice for managing user access in Mimecast.
