What is Data Loss Prevention in Cybersecurity?
Technology and policies that detect and prevent unauthorized transmission of sensitive data outside an organization. DLP tools monitor email, web uploads, USB transfers, and cloud storage for patterns matching credit card numbers, Social Security numbers, intellectual property, and other protected information.
Why Data Loss Prevention Matters for Your Cybersecurity Career
DLP is a major cybersecurity control for compliance with HIPAA, PCI DSS, GDPR, and other regulations. GRC analysts define DLP policies based on data classification requirements. Security engineers deploy and tune DLP systems to catch real data leaks without excessive false positives. CISOs justify DLP investments by tying them to regulatory risk reduction.
