The feature that directly helps in preventing data loss is Data Loss Prevention (DLP). DLP is specifically designed to monitor, detect, and respond to the unauthorized sharing or transmission of sensitive data. This includes personal information, payment details, and confidential business documents. By implementing DLP strategies, organizations can establish rules and policies that restrict the movement of this critical information, ensuring it is not sent outside the network without proper authorization.

In contrast, while encryption of network traffic enhances data security during transmission, it does not actively prevent data loss; instead, it protects data from being intercepted. Regular password updates improve security by making it harder for unauthorized users to gain access, but they do not directly address the issue of data leakage. Antivirus scanning is essential for detecting and removing malicious software but does not focus on safeguarding sensitive data from being lost or improperly accessed.
