Data loss prevention (DLP) tools are technologies that help to prevent unauthorized access, use, or transfer of personal data. DLP tools can monitor, detect, and block data leakage or exfiltration from various sources, such as endpoints, networks, cloud services, or email. DLP tools can also enforce data protection policies and compliance requirements, such as encryption, masking, or deletion of sensitive data. DLP tools can help to protect personal data from both internal and external threats, such as malicious insiders, hackers, or accidental exposure.
