What capability does Browser Isolation provide in the context of Zero Trust Exchange?

Browser Isolation is a critical feature within the Zero Trust Exchange framework, primarily designed to enhance security by protecting users from browser-based threats. It achieves this by isolating web browser sessions so that any malicious content encountered during browsing does not affect the user's device or network. This capability ensures that potentially harmful code or exploits encountered on the internet are kept within an isolated environment, significantly reducing the risk of data breaches and other security incidents.

By focusing on safeguarding users from threats that can arise directly from the browser, Browser Isolation allows organizations to maintain a secure environment while enabling users to access the web freely. This protective measure is essential in a Zero Trust context, where trust is never assumed, and security is prioritized at every point of access.

The other options do not accurately describe the primary function of Browser Isolation; for example, while it may enhance security, it does not specifically focus on improving browsing speed or providing access to dedicated search engines. Additionally, it does not limit isolation to external networks, as threats can also arise from internal sources or legitimate sites.
