How does cloud browser isolation protect against watering hole attacks?

Cloud browser isolation protects against watering hole attacks by isolating web content in a secure environment to block malicious code. This method creates a separation between the end user and potentially harmful web content. When users visit a compromised or malicious website, any scripts or harmful code present on that site run in the isolated environment rather than on the user's device. This means that any attempts by the malicious code to exploit the user’s device or steal sensitive data are thwarted, as the code is effectively contained within the isolated browser session.

This form of security is especially effective against watering hole attacks, where attackers compromise a legitimate website to target specific users. By preventing harmful code from executing on the user’s actual browser or operating system, cloud browser isolation significantly reduces the risk of exploitation and data breaches.

The other options do not address the specific mechanics of how watering hole attacks occur or how isolation directly counters them. Limiting user access might help in a broad sense, but it does not isolate threats. Enhancing browser speed is unrelated to security against such attacks, and allowing downloads from any site undermines the protective measures intended by isolation.
