How do Zscaler's Cloud Sandbox and Cloud Browser Isolation function?

Zscaler's Cloud Sandbox and Cloud Browser Isolation are designed to enhance security by analyzing potential threats in a controlled environment. The correct answer focuses on the key function of the Cloud Sandbox, which involves analyzing files in a sandbox environment before they can interact with the internal network or user devices.

When files are downloaded from the internet, they can contain malware or other harmful elements. By utilizing the Cloud Sandbox, Zscaler can execute and examine these files in an isolated environment, ensuring that any potential threats are identified and neutralized before the files are delivered to the end user. This proactive measure helps organizations safeguard their assets and users by minimizing the risk of malware infiltration.

The other options don't accurately reflect the functionalities of Zscaler's services. For example, blocking all external file downloads is an overly aggressive approach that could hinder legitimate business activities. Providing live streaming access to secure content does not pertain to the security features of analyzing files, nor does allowing unrestricted file sharing contribute to threat detection and prevention. Thus, the focus on analyzing files in a sandbox environment is the essence of Zscaler’s security approach.
