Which feature of Sophos is designed to detect and prevent data breaches?

The feature designed specifically to detect and prevent data breaches is Data Loss Prevention (DLP). DLP solutions focus on identifying when sensitive information is being accessed, used, or transmitted in an unauthorized manner. This involves monitoring data movement both within and outside the organization's network, ensuring that confidential data doesn't leave the organization without proper authorization. DLP employs various methods such as content inspection, contextual analysis, and predefined policies to safeguard against data leakage.

While other options like Cloud Security, Network Access Control, and Web Application Firewalls contribute to an organization's overall security posture, they do not primarily focus on the detection and prevention of data breaches in the same targeted manner as DLP. Cloud Security primarily protects data stored in cloud environments, Network Access Control restricts and manages access to network resources, and Web Application Firewalls protect web applications from threats and attacks. These functionalities are essential for security but do not specifically address the prevention of unauthorized data exposures like DLP does.
