Which type of DLP system prevents the transfer of outgoing data on the network?

Network-Based Data Loss Prevention (DLP) systems are designed specifically to monitor and control data flows over a network. This type of DLP system is effective at scanning network traffic in real-time and can detect sensitive information attempting to leave the network. By analyzing data packets as they travel through the network, it can identify potential breaches of policy related to data transfer, such as personal identification information, financial data, or intellectual property.

One of the primary functions of Network-Based DLP is to block or prevent the transmission of sensitive data outside the organization’s network perimeter. This capability is crucial for organizations that need to maintain strict compliance with regulations concerning data privacy and security.

In contrast, other types of DLP systems have different focal points. For instance, Cloud-Based DLP focuses on protecting sensitive data stored in cloud services, while Endpoint-Based DLP targets data at the individual devices through which the data is accessed or created. Therefore, while all these systems play important roles in a comprehensive data protection strategy, the specific capability to prevent the transfer of outgoing data directly on the network is uniquely associated with Network-Based DLP.
