DLP technologies are designed to prevent the unauthorized transmission or leakage of sensitive data, such as PII, intellectual property, or financial information, by employees or other insiders. DLP technologies can monitor, detect, and block data in motion, data at rest, and data in use across various channels, such as email, web, cloud, or removable devices. DLP technologies can also help enforce data security policies and compliance requirements.
