Which component is essential for the functioning of Mimecast Continuity Mode?

The essential component for the functioning of Mimecast Continuity Mode is Email Security. Continuity Mode ensures that organizations can maintain email services even during planned or unplanned outages of their primary email infrastructure. This mode functions within the Email Security framework, which provides a secure way to send and receive emails while ensuring that users have uninterrupted access to their messaging services.

Email Security plays a critical role by allowing emails to be sent and stored securely in the cloud. In the event of an outage, Mimecast can seamlessly deliver emails to end users directly from the cloud, ensuring business continuity. This capability relies heavily on the protocols, filtering, and security measures established within the Email Security component. Without it, the continuity service would lack the necessary infrastructure to maintain secure email exchange and access.

Other components, while important for various functionalities of the Mimecast platform, do not directly influence the operation of Continuity Mode as fundamentally as Email Security does.
