What is the role of Browser Isolation in Zscaler's security strategy?

Browser Isolation is a crucial component of Zscaler's security strategy, particularly in managing how users interact with the web. The primary function of Browser Isolation is to prevent access to suspicious websites effectively.

By isolating the browsing activity, Zscaler creates a safe environment where users can access potentially risky content without exposing their internal systems to threats such as malware or phishing attacks. This isolation allows for a secure browsing experience by ensuring that if a user visits a site deemed suspicious, any malicious content is contained within the isolated session, not allowing it to interact with the user's actual device or corporate network.

This capability is particularly important in today's landscape where threats can come from legitimate-looking websites that may be compromised or designed to breach security. Through this mechanism, Zscaler can protect users from threats while allowing them to benefit from the information available on the broader internet.

The other provided options do not encapsulate the complete role of Browser Isolation. Blocking all web traffic to unknown sites may be overly restrictive and not practical for user productivity. Offering unrestricted browsing for privileged users contradicts the very purpose of isolating potential risks. Lastly, while securing user data is essential, it is not the primary focus of Browser Isolation, which centers on creating a safe browsing context.
