Which of the following is a common feature of a Cloud Email Gateway?

Centralized management of policies is a fundamental feature of a Cloud Email Gateway. This functionality allows administrators to manage, configure, and enforce email security policies from a single point of control, streamlining the process of maintaining security measures across an organization. By having a centralized system, it becomes significantly easier to implement consistent policies, monitor traffic, and quickly respond to threats or compliance issues.

This centralized approach enhances operational efficiency and ensures that all users are protected according to the same set of standards. It also simplifies reporting and auditing, allowing organizations to demonstrate compliance with regulations and security best practices.

In contrast, local database storage is not typical of Cloud Email Gateways since they rely primarily on cloud infrastructure for data management and processing, facilitating scalability and accessibility. Installation on physical servers only contradicts the cloud-based model of these gateways, which are designed for deployment in cloud environments. Limited integration with other services is also not characteristic of a Cloud Email Gateway, as these solutions generally support extensive APIs and interoperability with a variety of third-party applications to enhance email security and management functionalities.
