Data Loss Prevention (DLP)

A set of tools and processes designed to prevent unauthorized access, use, or transfer of sensitive data.

Understanding Data Loss Prevention (DLP)


DLP systems help organizations identify, classify, and protect sensitive information, such as personally identifiable information (PII), financial records, intellectual property, and trade secrets. These solutions are widely used to prevent insider threats, accidental data exposure, and cyber threats that aim to steal or manipulate sensitive data.

Key Components of DLP


  1. Content Inspection – Scans files, emails, and databases for sensitive information.

  2. Policy Enforcement – Blocks unauthorized transfers of classified files via email, USB, or cloud uploads.

  3. User Activity Monitoring – Tracks employee access and data-sharing behaviors.

  4. Data Encryption & Masking – Protects sensitive data with encryption, redaction, or tokenization.

Common Applications of DLP


  • Regulatory Compliance – Ensures adherence to GDPR, HIPAA, PCI-DSS, and SOX data protection laws.

  • Insider Threat Prevention – Detects unauthorized data transfers by employees.

  • Cloud Security – Monitors data shared with cloud-based storage (e.g., Google Drive, OneDrive).

  • Intellectual Property Protection – Prevents trade secrets or sensitive R&D data leaks.
