Which capability is essential for identifying threats through inspection at scale?

Cloud Browser Isolation is essential for identifying threats through inspection at scale because it allows organizations to segregate browsing activities from the internal network. This capability enables the analysis of web traffic in a controlled environment, effectively isolating potentially harmful web content before it can interact with the organizational systems.

By utilizing this technology, organizations can monitor and inspect web traffic for malware and other threats without risking exposure to their networks. This method creates a secure buffer, which not only enhances security but also provides detailed insights into browsing behavior, making it easier to detect patterns or anomalies that could indicate a security threat.

In contrast, the other options do not specifically focus on the real-time assessment of web content at scale. Data loss prevention primarily aims to prevent the unauthorized transfer of sensitive data rather than the active identification of external threats. VPN encryption emphasizes the secure transmission of data over the internet, but it does not inherently include extensive threat inspection capability. Meanwhile, incident response planning deals with the processes and strategies to respond to security incidents after they occur, rather than the proactive threat identification through real-time inspection.
