What technology can be used to prevent unauthorized data exfiltration?

Data Loss Prevention (DLP) technology specifically focuses on safeguarding sensitive information from being accessed, misused, or transferred outside an organization without authorization. DLP solutions monitor and control data in use, in motion, and at rest. By implementing policies that detect unauthorized attempts to transfer data across various channels, such as email, web uploads, or removable storage devices, DLP solutions help ensure that proprietary or sensitive data does not leave the organization's network without proper authorization.

In contrast to DLP, other technologies like firewalls primarily act as barriers to control network traffic based on security rules but do not actively monitor for specific data exfiltration behaviors. Virtual Private Networks (VPNs) secure data in transit and protect against eavesdropping but do not prevent the actual unauthorized transfer of sensitive information. Intrusion Detection Systems (IDS) monitor network traffic for suspicious activities and alert administrators but do not take preventative measures against data exfiltration itself. Thus, DLP stands out as the most effective choice for preventing unauthorized data exfiltration by actively identifying and stopping improper data transfers based on defined security policies.
