Email DLP Importance

Email remains primary vector for data loss through misdirected messages, attachment errors, and malicious exfiltration. Email DLP inspects outbound email content and attachments, preventing sensitive data leakage while maintaining business communication.

Email DLP Capabilities

Email DLP scans message content and attachments for sensitive data, checks recipient domains and addresses, analyzes conversation context, enforces encryption for sensitive emails, and provides user notifications educating about violations.

Detection Methods

Email DLP uses content analysis (data type detection), attachment scanning including compressed files, image OCR for screenshots, contextual analysis of subject and body, and behavioral analysis flagging unusual sending patterns.

Enforcement Actions

Actions include user notifications requesting confirmation, manager approval workflows for sensitive data, automatic encryption of qualifying emails, blocking delivery and quarantine for policy violations, and logging for audit and investigation.

User Experience

Balance security with productivity through clear policy communication, educational notifications explaining violations, streamlined approval processes, and exceptions for trusted partners. Poor user experience leads to shadow IT bypassing controls.
